A localization approach uses a 3D map for an area made up of 3D points. A mobile device downloads the 3D map and localizes itself against the 3D map by comparing images captured by a camera on the mobile device to the 3D map. On-device localization obviates the need to send keyframes to the server and greater localization accuracy may be achieved as a larger number of images (e.g., all of the images captured by the device's camera) may be compared to the map. Tracking may also be performed on-device by comparing additional image captured by a camera on the mobile device to the 3D map in view of sensor data (e.g., inertial data).

ON-DEVICE LOCALIZATION AND TRACKING WITHOUT KEYFRAMES
A localization approach uses a 3D map for an area made up of 3D points. A mobile device downloads the 3D map and localizes itself against the 3D map by comparing images captured by a camera on the mobile device to the 3D map. On-device localization obviates the need to send keyframes to the server and greater localization accuracy may be achieved as a larger number of images (e.g., all of the images captured by the device's camera) may be compared to the map. Tracking may also be performed on-device by comparing additional image captured by a camera on the mobile device to the 3D map in view of sensor data (e.g., inertial data).
The present disclosure describes an online system that applies template-based facial augmentations to images as part of an augmented reality experience. A facial augmentation template is a template for an augmented reality (AR) modification to apply to a user's face. These templates include a structure for how the augmentation should be applied to the face and display parameters that a user can set for how the templates should be rendered (e.g., color, specularity, or opacity). The online system identifies feature points on a 3D model of the user's face that correspond to features on the user's actual face, and localizes the template relative to the 3D model by mapping anchor points of the template to corresponding feature points on the 3D model. The online system renders the facial augmentation template at the localization to generate an augmented image of the user's face.
An online computing system generates and uses usability heatmaps to ensure that AR content is presented in suitable locations within geographic areas. To generate a usability heatmap, the online system accesses geographic data describing a geographic area for which the online system provides AR content services and identifies a set of portions of the geographic area. The online system identifies subsets of the geographic data for each of the portions of the geographic area and computes a usability score for each of the portions. The online system generates a usability heatmap based on the computed usability scores for the portions of the geographic area and stores the heatmap in a heatmap database that stores usability heatmaps for different geographic areas. The online system may use the heatmaps in the database to generate AR content when requested by client devices.
An online system uses a pose prior model and a pose objective function to estimate the pose of a client device. A pose prior model is a model for prior information known about client devices and their poses without reference to a particular client device and its pose data. The online system receives pose data from a client device and computes an estimated pose for the client device based on the received pose data, the pose prior model, and a generated initial candidate pose for the client device. The online system uses these as inputs to a pose objective function and optimizes the pose objective function to estimate a pose for the client device. The online system transmits this estimated pose to the client device, and may use the estimated pose as the pose for the client device for the purposes of delivering content to the user.

A set of code syntax is parsed to identify relevant resources rather than being executed or compiled. The syntax serves as a domain-specific language in that it can be used only to obtain resources that have been validated and included in the syntax. Developers write code to implement their components in a browser-based development environment. The development environment provides a library of user interface components that may be used and manipulated by developers. The studio parses the developer's code and syntax statements to infer a set of the user interface components that allows other developers to configure these components using the development environment's user interface.
A development system provides an editor and a simulator between which changes are bi-directionally synchronized. As the simulator runs the application logic, objects may be spawned and destroyed. Object properties (e.g., colors, positions, behaviors, etc.) can also change as time passes. The developer can see these changes in the editor view in real time. The developer can make changes in the editor view that persist and are synchronized in real time to the simulator.
A system may provision an application-specific cloud account for a backend component of a software application. The system may receive a request from a client system executing a client side component of the software application, the request including authorization credentials and a version identifier for the backend component. The system may validate the authorization credentials to determine the client system is authorized to access the requested virtual reality content. The system may identify a backend version of the backend component associated with the version identifier in the request. The system may load, into the cloud account, the backend component corresponding to the identified backend version. The system may execute the loaded backend component to process the request and generate the requested virtual reality content. The system may return the requested virtual reality content to the client system.
A depth estimation model leverages a geometry-rendered depth map from a low-cost geometry model to provide depth hints. The model is trained and configured to input a time series of frames including a target frame. The time series of images are captured as monocular video data by a camera assembly. Applying the model includes: applying a feature encoder to extract visual features forming a feature map for each frame, matching features across the features maps forming a cost volume, obtaining a geometry-rendered depth map from the low-cost geometry model of the scene based on a pose of the target frame, modifying the cost volume based on the geometry-rendered depth map, and applying a depth decoder to the modified cost volume to generate the depth map for the target frame. A client device implementing the model may generate virtual content using the depth map to display the target frame of the scene augmented with the virtual content.
A machine learning model classifies points of interest in a parallel reality game hosted by a server. The server generates training data sets that include verified properties for points of interest. The machine learning model may predict unverified properties for points of interest. Players in the parallel reality game may input properties for the points of interest. The machine learning model use the received properties from players as inputs to the machine learning model to verify unverified properties or generate new properties for the points of interest. The server may classify the points of interest as suitable for particular activities, and the server may use the classifications for future activities within the parallel reality game.

MAGNETIC FIELD VECTOR MAP FOR ORIENTATION DETERMINATION
The present disclosure describes a method for estimating a pose of a client device using a magnetic field vector map. The method includes receiving a plurality of magnetic field measurements from a plurality of client devices, each magnetic field measurement describing a magnetic field vector at a geographic location. The method further includes grouping the magnetic field measurements into one or more region groups, aggregating the magnetic field measurements in each region group to generate a probability distribution of magnetic field vectors associated with the geographic region, determining a magnetic field vector within each geographic region, and generating a magnetic field vector map. Based on the magnetic field vector map, the method may include estimating a pose of a client device based on a user location of the client device and received magnetic field vector from the client device.
A client device estimates an error in a heading component of a magnetometer measurement based on an error in a vertical component of the magnetometer measurement. The client device receives a three-dimensional measurement from a magnetometer including a heading and a vertical component. The client device identifies an expected vertical component based on a position of the client device and a magnetic map. The client device generates an error estimate based on the vertical component of the three-dimensional measurement and the expected vertical component. The client device compares the error to an error threshold and, in response to the error estimate being less than an error threshold, determines a pose of the client device based on the heading. The client device displays augmented reality content to the user using the pose.
A method for determining a metric relative pose between a target image and a reference image is disclosed. The method includes receiving the target image depicting a scene captured by a camera assembly of a client device. The method includes applying a machine-learning model to the target image to determine a metric relative pose between the target image and a reference image, wherein the metric relative pose represents a transformation from a pose of the reference image to a pose of the target image that is scaled to physical dimensions of the scene. The machine-learning model may include a keypoint network for determining a keypoint distribution including the spatial coordinates of keypoints extracted from each image. The machine-learning model may establish correspondences between the keypoint distribution of the target image and the keypoint distribution of the reference image. Based on the identified correspondences, the machine-learning model may regress the metric relative pose. With the metric relative pose, augmented reality content may be generated and displayed informed by the physical dimensions of the scene described by the metric relative pose.

A message router partially decodes messages to determine how to route the messages. The message router receives a message and identifies a field of the message as a candidate field for including an envelope identifier that indicates an envelope type of the message. The envelope type of the message indicates where information, such as where to route the message, is stored within the message. The message router attempts to decode the candidate field to determine whether the candidate field includes the envelope identifier, and responsive to the candidate filed including the envelope identifier, the message router determines the envelope type of the message. The message router routes the message according to the envelope type.
An image of a hand is captured by a camera. The captured image is rectified by establishing a canonical camera space and mapping predictions back to an original camera space. A set of 2D keypoints, a set of root-relative vertices, and a set of weights are predicted based on the rectified image. Using the set of root-relative vertices, a set of 3D keypoints that correspond to the set of 2D keypoints are obtained. A global camera space hand mesh prediction is generated in 3D space based on the set of 2D keypoints, the set of weights, and the set of 3D keypoints. A virtual element is output in a virtual space based on the generated global camera space hand mesh prediction.
Depth maps are generated based on a sequence of posed images captured by a camera, the depth maps are fused into a truncated signed distance function (TSDF), and an initial estimate of 3-dimensional (3D) scene geometry is generated by extracting a 3D mesh via the TSDF. 3D embeddings are estimated for each vertex in the 3D mesh by mapping each vertex to a multi-view consistent plane embedding space such that vertices on a same plane map to nearly a same place in the embedding space. The vertices are clustered into 3D plane instances based on respective 3D embeddings and geometry information defined by the 3D mesh to create a planar representation of the scene. A location of a virtual element in a virtual world of an augmented reality game is determined based on the planar representation.

A user selects an object on the display of a mobile device and a corresponding coordinate in a 3D map including the object is selected. A bounding volume and center point of the object in 3D space is estimated based on segmenting the image to identify the object and the depth of pixels in the segmented region depicting the object. The user follows an approximately circular path around the object, pointing a camera at the object, and receives audio and/or haptic feedback regarding orientation of the camera, distance from the object, or speed of progression along the path. As the user moves the camera, a 3D scan of the object is generated. The center point of the object may be recalculated as the user progresses along the path.
This disclosure pertains to a scene-agnostic, map-relative pose regression method. The pose regressor is conditioned on a scene-specific map representation such that its pose predictions are relative to the scene map. This allows training of the pose regressor across multiple scenes to learn the generic relation between a scene-specific map representation and the camera pose. The map-relative pose regressor can then be applied to new map representations.

The present disclosure describes a method for calibrating a magnetic sensor of a client device. The method may include receiving a set of magnetic field measurements, each of which includes a device location, an orientation of the client device, and an observed magnetic field vector measured by the magnetic sensor. The method may include computing a device correction vector for the client device based on the set of magnetic field measurements. For each magnetic field measurement, the method includes determining a world magnetic field vector at the device location of the magnetic field measurement, computing an expected measured magnetic field vector at the device location, accessing an estimated device correction vector for the client device, computing an expected adjusted vector for the client device, comparing the observed magnetic field vector associated with the magnetic field measurement and the expected adjusted vector, and computing the device correction vector based on the comparison.
A relocalizer model for an environment is trained using an iterative process. To initialize the relocalizer model, an initial image is registered with its camera pose established as the reference. In each subsequent iteration of training, the relocalizer model is applied to additional images to predict pose estimates for the images. The images and their pose estimates are then leveraged in retraining of the relocalizer model. In general, the training of the relocalizer model entails extracting scene coordinates for pixels of a training image. The scene coordinates are then projected into a projection based on the pose estimate of the training image. A loss is calculated between the projection and the training image. And parameters of the relocalizer model are adjusted to minimize the loss. The iterative training may continue until an end condition is met. The trained relocalizer model is configured to input an image of the environment and to output the camera pose for the image.
An augmented reality system generates computer-mediated reality on a client device. The client device has sensors including a camera configured to capture image data of an environment and a location sensor to capture location data describing a geolocation of the client device. The client device creates a three-dimensional (3-D) map with the image data and the location data for use in generating virtual objects to augment reality. The client device transmits the created 3-D map to an external server that may utilize the 3-D map to update a world map stored on the external server. The external server sends a local portion of the world map to the client device. The client device determines a distance between the client device and a mapping point to generate a computer-mediated reality image at the mapping point to be displayed on the client device.
The present disclosure describes an online system that applies template-based facial augmentations to images as part of an augmented reality experience. A facial augmentation template is a template for an augmented reality (AR) modification to apply to a user's face. These templates include a structure for how the augmentation should be applied to the face and display parameters that a user can set for how the templates should be rendered (e.g., color, specularity, or opacity). The online system identifies feature points on a 3D model of the user's face that correspond to features on the user's actual face, and localizes the template relative to the 3D model by mapping anchor points of the template to corresponding feature points on the 3D model. The online system renders the facial augmentation template at the localization to generate an augmented image of the user's face.
An AR client device generates and uses a background model to identify portions of images that depict the sky. A background model is a model that represents where the sky is visible for the client device. To identify a sky background portion of an image, a client device can map an image onto the background model and thereby determine which portion of the image represents the sky. The client device can use the identified sky background portion to augment the image to include AR content in the sky. To generate the background model, the client device applies a background detection model to a set of images to generate background probability images. The background probability images are mapped onto a background model using orientation data captured by the client device to update the background model based on the background probability image.

STRUCTURE LINE GENERATION FOR USER DEVICE POSE PREDICTION
A client device, or an online system, uses structure lines that are generated based on an image to predict a pose of the client device. Structure lines are lines that delineate structures in the physical world depicted in the image. The client device also uses a structure model to predict its pose. A structure model is a model that represents structures in the physical world within an area. The client device predicts its pose based on the structure model and the structure lines by applying an objective function. The client device may then iteratively update the estimated pose and score the updated poses until the client device identifies an estimated pose at which the structure lines sufficiently fit the structure model.
A method, system, and computer-readable storage medium are disclosed for displaying virtual elements (e.g., AR content) in a physical environment by a client device using a virtual camera pose that is different from the pose of the physical camera used to capture images of the physical environment. The client device uses a three-dimensional (3D) map (e.g., a topographical mesh) of the physical environment to determine a pose (a position and orientation) of the camera of the client device. The 3D map can include geometry, colors, textures, or any other suitable information describing the physical environment.

A method of determining a position for a virtual object is described. A location of a client device is determined, and, based on the determined location a set of map segments is retrieved. A virtual object is determined to be displayed on the client device. Relation vectors between the virtual object and each map segment of the retrieved set of map segments are obtained. Each relation vector is weighted based on object parameters of the virtual object. A position to display the virtual object is determined based on the weighted relation vectors. The virtual object is provided for display on the client device as the determined position.

The present disclosure describes approaches for evaluating interest points for localization uses based on a repeatability of the detection of the interest point in images capturing a scene that includes the interest point. The repeatability of interest points is determined by using a trained repeatability model. The repeatability model is trained by analyzing a time series of images of a scene and determining repeatability functions for each interest point in the scene. The repeatability function is determined by identifying which images in the time series of images allowed for the detection of the interest point by an interest point detection model.

EAR FEATURE DETECTION AND LOCATION FOR FACIAL AUGMENTED REALITY
A client device provides AR content to a user tracks features of the user's ears. The client device builds a model of the user's head that represents the distances between the user's facial features and features of the user's ears. The client device generates this user head model by identifying facial feature points in an image. The client device also applies an ear feature detection model to the image, which identifies 2D points in the image where ear features are depicted. The client device generates the model based on the 3D facial feature points and the 2D ear feature points. For example, the client device may use a feature relationship model that describes the general relationships between facial features and ear points. Once the client device has generated the user head model, the client device uses the user head model to estimate the position of the ear features in 3D.

A client device selects animations for an AR character by prompting a large language model (LLM) to select from a set of possible animations for the AR character. The client device captures an image of its environment using a camera and identifies objects that are depicted in the image. The client device generates a prompt for an LLM that instructs the LLM to select from a set of candidate actions for an AR character to perform based on the identified objects. The LLM returns a response to the client device and the client device extracts a set of selected actions from the LLM's response. The client device identifies a set of animations that correspond to the actions selected by the LLM and renders AR content that depicts the AR character performing those actions. The client device augments the captured image to include the AR content and displays the augmented image.
An augmented reality (“AR”) device applies smooth correction methods to correct the location of the virtual objects presented to a user. The AR device may apply an angular threshold to determine whether a virtual object can be moved from an original location to a target location. An angular threshold is a maximum angle by which a line from the AR device to the virtual object can change within a timestep. Similarly, the AR device may apply a motion threshold, which is a maximum on the distance that a virtual object's location can be corrected based on the motion of the virtual object. Furthermore, the AR device may apply a pixel threshold to the correction of the virtual object's location. A pixel threshold is a maximum on the distance that a pixel projection of the virtual object can change based on the virtual object's change in location.
An online system generates and stores virtual models of physical spaces. These virtual models represent physical objects within the physical spaces through 3D representations of those objects. A content development system can request a virtual model associated with a physical space and modify the virtual model to include virtual objects. The content development system transmits the modified virtual model to be stored by the online system. A client device requests the modified virtual model from the online system when the client device is posed near the physical space. The client device uses the modified virtual model to display a modified video feed that displays the virtual content generated by the content development system as an augmented reality experience.
A system determines an accuracy of a set containing a plurality of sensor location measurements of a client device and generating a set of sensor location measurements labeled with an associated accuracy estimate, is presented. The system receives a plurality of sensor location measurements of the client device generated by a location sensor. The system may determine the accuracy of a sensor location measurement by comparing the sensor location measurement to a reference location measurement, such as VIO location measurements computed using VIO data. The system computes a first set of location translations for the set of sensor location measurements and a second set of location translations for the set of VIO location measurements. The system may calculate a measurement difference between each corresponding pair of location translations from the first and second set, identify measurement differences that exceed a threshold, and label the corresponding sensor location measurement as inaccurate.

Magnetic field vector map for orientation determination
The present disclosure describes a method for estimating a pose of a client device using a magnetic field vector map. The method includes receiving a plurality of magnetic field measurements from a plurality of client devices, each magnetic field measurement describing a magnetic field vector at a geographic location. The method further includes grouping the magnetic field measurements into one or more region groups, aggregating the magnetic field measurements in each region group to generate a probability distribution of magnetic field vectors associated with the geographic region, determining a magnetic field vector within each geographic region, and generating a magnetic field vector map. Based on the magnetic field vector map, the method may include estimating a pose of a client device based on a user location of the client device and received magnetic field vector from the client device.
A system includes a first sensor system and a second sensor system. The first sensor system includes a first internal clock, a first sensor configured to generate data describing an environment, and a Universal Serial Bus (USB) module. The second sensor system includes a second internal clock and a controller configured to perform a precision time protocol (PTP) to synchronize the second internal clock with the first internal clock. The precision time protocol includes transmitting timestamped messages encoded in USB bulk messages between the first sensor system and the second sensor system. The timestamped messages may be encoded in USB musical instrument digital interface (MIDI) bulk messages.
An online system uses a visual positioning system (VPS) model to verify the location of a client device for anti-spoofing measures. The online system receives ostensible pose data and image data from the client device. This pose data and image data are ostensibly captured by the client device at the same time, or within some threshold time of each other. The online system determines whether they match according to a VPS model. The online system uses the VPS model to output candidate poses for the client device based on the received image data and compares those candidate poses to the pose in the received pose data. If the differences between the candidate poses and the pose from the received pose data exceed a threshold, the online system may determine that the received pose data and image data do not match and thus are likely being spoofed.

DETERMINING VISUAL OVERLAP OF IMAGES BY USING BOX EMBEDDINGS
An image matching system for determining visual overlaps between images by using box embeddings is described herein. The system receives two images depicting a 3D surface with different camera poses. The system inputs the images (or a crop of each image) into a machine learning model that outputs a box encoding for the first image and a box encoding for the second image. A box encoding includes parameters defining a box in an embedding space. Then the system determines an asymmetric overlap factor that measures asymmetric surface overlaps between the first image and the second image based on the box encodings. The asymmetric overlap factor includes an enclosure factor indicating how much surface from the first image is visible in the second image and a concentration factor indicating how much surface from the second image is visible in the first image.

Depth Image Generation Using a Graphics Processor for Augmented Reality
An AR device displays virtual objects to users as part of an AR experience by generating a depth image by rendering the depth image from a three-dimensional (3D) world model. The AR device receives an image from a camera and estimates its physical pose in the real world when the image was captured. The AR device accesses the 3D world model and estimates a virtual pose within a 3D world model that corresponds to the estimated physical pose in the real world. The AR device uses the virtual pose to render the depth image using the 3D world model. The AR device may use a graphics processor to render the depth image from a camera view corresponding to the virtual pose. The AR device uses the depth image to present content to the user over the image captured by the camera.
An online system uses a pose prior model and a pose objective function to estimate the pose of a client device. A pose prior model is a model for prior information known about client devices and their poses without reference to a particular client device and its pose data. The online system receives pose data from a client device and computes an estimated pose for the client device based on the received pose data, the pose prior model, and a generated initial candidate pose for the client device. The online system uses these as inputs to a pose objective function and optimizes the pose objective function to estimate a pose for the client device. The online system transmits this estimated pose to the client device, and may use the estimated pose as the pose for the client device for the purposes of delivering content to the user.

The disclosure describes a method for calibrating a magnetic sensor of a client device. The method may include receiving a set of magnetic field measurements, each of which includes a device location, an orientation of the client device, and an observed magnetic field vector measured by the magnetic sensor. The method may include computing a device correction vector for the client device based on the set of magnetic field measurements. For each magnetic field measurement, the method includes determining a world magnetic field vector at the device location of the magnetic field measurement, computing an expected measured magnetic field vector at the device location, accessing an estimated device correction vector for the client device, computing an expected adjusted vector for the client device, comparing the observed magnetic field vector associated with the magnetic field measurement and the expected adjusted vector, and computing the device correction vector based on the comparison.
A method for training a depth estimation model and methods for use thereof are described. Images are acquired and input into a depth model to extract a depth map for each of the plurality of images based on parameters of the depth model. The method includes inputting the images into a pose decoder to extract a pose for each image. The method includes generating a plurality of synthetic frames based on the depth map and the pose for each image. The method includes calculating a loss value with an input scale occlusion and motion aware loss function based on a comparison of the synthetic frames and the images. The method includes adjusting the plurality of parameters of the depth model based on the loss value. The trained model can receive an image of a scene and generate a depth map of the scene according to the image.
A machine learned model may calculate a relative pose between a pair of overlapping images of a scene. The model may be applied to predict one or more errors (e.g., translation error and/or rotation error) in the relative pose between the pair of overlapping images. The model may leverage epipolar geometry to compare features of the overlapping images in a dense manner. For example, the two-view geometry model may incorporate the epipolar geometry into an attention layer of a neural network for one or more different fundamental matrix hypotheses. The model may output one or more predicted errors for the pair of images along with a proposed fundamental matrix hypothesis. A client device may select a fundamental matrix associated with the lowest predicted one or more errors. The client device may then display content that accounts for the predicted one or more errors.

The present disclosure describes approaches to camera re-localization that improve the accuracy of re-localization determinations by performing simulated consistency checks for three-dimensional maps. Client devices associated with users of a location-based application transmit image scans to a game server, which divides the received scan data into mapping sets used to generate 3D maps of environments and validation sets used to test the accuracy of the maps. To perform the testing, the game server identifies query scans in the validation set having GPS coordinates within a threshold distance of the mapped location and uses the 3D map of the environment to generate a pose estimate for each frame. The results of the localization queries are analyzed by comparing differences between the localization pose estimates and differences between the poses of independent pairs of frames in the query scan to evaluate the accuracy of the 3D map.

The present disclosure describes a location-based application in which users can attach media content to geographic locations. Other users can later experience the media content when in proximity to the geographic content or via a map interface displaying indications of media content in the vicinity of the viewing user. When users experience media content attached to a geographic location they may initiate communication with the creator of the media content. Additionally, the creator or viewer of a video or photograph of a geographic location may select an object depicted in the video or photograph to create a 2D or 3D virtual object representing the depicted object. This virtual object may be held by the user (e.g., in a virtual bag) or dropped at the same or a different geographic location where it may be viewed and interacted with by other users in an augmented reality environment.
Methods and systems for creating accurate three-dimensional representations of environments using neural radiance fields regularized by denoising diffusion models are disclosed. Receiving a plurality of images representing an environment, a scene representation model is trained to create the three-dimensional model of the environment. Using these images, the virtual rays are sampled from training viewpoints within the environment. The scene representation model is then applied to these rays to generate simulated images of the environment from the training viewpoints. These simulated images undergo a regularization process that uses a denoising diffusion model to determine color gradients and depth gradients in each simulated image. The scene representation model is trained with this data to create the final three-dimensional model of the environment. This model is provided to the requesting client device to generate the three-dimensional representation and create a virtual object within the environment.

An augmented reality system generates computer-mediated reality on a client device. The client device has sensors including a camera configured to capture image data of an environment. The augmented reality system generates a first 3D map of the environment around the client device based on captured image data. The server receives image data captured from a second client device in the environment and generates a second 3D map of the environment. The server links the first and second 3D together in a singular 3D map. The singular 3D map may be a graphical representation of the real world using nodes that represent 3D maps generated by image data captured at client devices and edges that represent transformations between the nodes.

The present disclosure describes approaches to camera re-localization that improve the speed and accuracy with which pose estimates are generated by fusing output of a computer vision algorithm with data from a prior model of a geographic area in which a user is located. For each candidate pose estimate output by the algorithm, a game server maps the estimate to a position on the prior model (e.g., a specific cell on a heatmap-style histogram) and retrieves a probability corresponding to the mapped position. A data fusion module fuses, for each candidate pose estimate, a confidence score generated by the computer vision algorithm with the location probability from the prior model to generate an updated confidence score. If an updated confidence score meets or exceeds a score threshold, a re-localization module initiates a location-based application (e.g., a parallel reality game) based on the associated candidate pose estimate.

Accelerated Coordinate Encoding: Learning to Relocalize in Minutes Using RBG and Poses
A set of training images of one or more environments and corresponding metadata are received. The metadata includes camera pose and intrinsics. A relocalizer model is trained using the set of training images and the corresponding metadata to generate predict scene coordinates corresponding to pixels in an image of an environment. The relocalizer model includes a scene-agnostic convolutional network and a scene-specific regression network. A set of query images of an environment is received and the trained relocalizer model is applied to the set of query images of the environment to generate predicted scene coordinates corresponding to the pixels in a query image. A pose solver algorithm is applied to the predicted scene coordinates to generate a camera pose.
A system generates augmented reality content by generating an occlusion mask via implicit depth estimation. The system receives input image(s) of a real-world environment captured by a camera assembly. The system generates a feature map from the input image(s), wherein the feature map comprises abstract features representing depth of object(s) in the real-world environment. The system generates an occlusion mask from the feature map and a depth map for the virtual object. The depth map for the virtual object indicates a depth of each pixel of the virtual object. The occlusion mask indicates pixel(s) of the virtual object that are occluded by an object in the real-world environment. The system generates the composite image based on a first input image at a current timestamp, the virtual object, and the occlusion mask. The composite image may then displayed on an electronic display.
A machine learning model classifies points of interest in a parallel reality game hosted by a server. The server generates training data sets that include verified properties for points of interest. The machine learning model may predict unverified properties for points of interest. Players in the parallel reality game may input properties for the points of interest. The machine learning model use the received properties from players as inputs to the machine learning model to verify unverified properties or generate new properties for the points of interest. The server may classify the points of interest as suitable for particular activities, and the server may use the classifications for future activities within the parallel reality game.

Location determination and mapping with 3D line junctions
A system and method for determining a location of a client device is described herein. In particular, a client device receives images captured by a camera at the client device. The client device identifies features in the images. The features may be line junctions, lines, curves, or any other features found in images. The client device retrieves a 3D map of the environment from the map database and compares the identified features to the 3D map of the environment, which includes map features such as map line junctions, map lines, map curves, and the like. The client device identifies a correspondence between the features identified from the images and the map features and determines a location of the client device in the real world based on the correspondence. The client device may display visual data representing a location in a virtual world corresponding to the location in the real world.

Smooth object correction for augmented reality devices
An augmented reality (“AR”) device applies smooth correction methods to correct the location of the virtual objects presented to a user. The AR device may apply an angular threshold to determine whether a virtual object can be moved from an original location to a target location. An angular threshold is a maximum angle by which a line from the AR device to the virtual object can change within a timestep. Similarly, the AR device may apply a motion threshold, which is a maximum on the distance that a virtual object's location can be corrected based on the motion of the virtual object. Furthermore, the AR device may apply a pixel threshold to the correction of the virtual object's location. A pixel threshold is a maximum on the distance that a pixel projection of the virtual object can change based on the virtual object's change in location.
The present disclosure describes approaches to camera re-localization that improve the accuracy of re-localization determinations by performing simulated consistency checks for three-dimensional maps. Client devices associated with users of a location-based application transmit image scans to a game server, which divides the received scan data into mapping sets used to generate 3D maps of environments and validation sets used to test the accuracy of the maps. To perform the testing, the game server identifies query scans in the validation set having GPS coordinates within a threshold distance of the mapped location and uses the 3D map of the environment to generate a pose estimate for each frame. The results of the localization queries are analyzed by comparing differences between the localization pose estimates and differences between the poses of independent pairs of frames in the query scan to evaluate the accuracy of the 3D map.
An image matching system for determining visual overlaps between images by using box embeddings is described herein. The system receives two images depicting a 3D surface with different camera poses. The system inputs the images (or a crop of each image) into a machine learning model that outputs a box encoding for the first image and a box encoding for the second image. A box encoding includes parameters defining a box in an embedding space. Then the system determines an asymmetric overlap factor that measures asymmetric surface overlaps between the first image and the second image based on the box encodings. The asymmetric overlap factor includes an enclosure factor indicating how much surface from the first image is visible in the second image and a concentration factor indicating how much surface from the second image is visible in the first image.

A method of determining a position for a virtual object is described. A location of a client device is determined, and, based on the determined location a set of map segments is retrieved. A virtual object is determined to be displayed on the client device. Relation vectors between the virtual object and each map segment of the retrieved set of map segments are obtained. Each relation vector is weighted based on object parameters of the virtual object. A position to display the virtual object is determined based on the weighted relation vectors. The virtual object is provided for display on the client device as the determined position.

Refining camera re-localization determination using prior pose model
The present disclosure describes approaches to camera re-localization that improve the speed and accuracy with which pose estimates are generated by fusing output of a computer vision algorithm with data from a prior model of a geographic area in which a user is located. For each candidate pose estimate output by the algorithm, a game server maps the estimate to a position on the prior model (e.g., a specific cell on a heatmap-style histogram) and retrieves a probability corresponding to the mapped position. A data fusion module fuses, for each candidate pose estimate, a confidence score generated by the computer vision algorithm with the location probability from the prior model to generate an updated confidence score. If an updated confidence score meets or exceeds a score threshold, a re-localization module initiates a location-based application (e.g., a parallel reality game) based on the associated candidate pose estimate.

MAPPING TRAVERSABLE SPACE IN A SCENE USING A THREE-DIMENSIONAL MESH
A parallel-reality game uses a virtual game board having tiles placed over an identified traversable space corresponding to flat regions of a scene. A game board generation module receives one or more images of the scene captured by a camera of a mobile device. The game board generation module obtains a topographical mesh of the scene based on the received one or more images. The game board generation module then identifies a traversable space within the scene based on the obtained topographical mesh. The game board generation module determines a location for each of a set of polygon tiles in the identified traversable space. The game board generation module also allows for queries to identify parts of the game board that meet one or more provided criterion.

Efficient GPU/CPU pipeline for providing augmented reality content
Implementations generally relate to providing augmented reality in a web browser. In one implementation, a method includes capturing images of a physical scene with a camera of a device. The method further includes determining motion of the camera using six degrees of freedom (6DoF) markerless tracking. The method further includes overlaying virtual three-dimensional (3D) content onto a depicted physical scene in the images, resulting in augmented reality (AR) images. The method further includes rendering the AR images in a browser of the device.
A scene reconstruction model is disclosed that outputs a heightfield for a series of input images. The model, for each input image, predicts a depth map and extracts a feature map. The model builds a 3D model utilizing the predicted depth maps and camera poses for the images. The model raycasts the 3D model to determine a raw heightfield for the scene. The model utilizes the raw heightfield to sample features from the feature maps corresponding to positions on the heightfield. The model aggregates the sampled features into an aggregate feature map. The model regresses a refined heightfield based on the aggregate feature map. The model determines the final heightfield based on a combination of the raw heightfield and the refined heightfield. With the final heightfield, a client device may generate virtual content augmented on real-world images captured by the client device.

Controlling Augmented Reality Content Via Selection of Real-World Locations or Objects
A client device and a controller allow a user to control AR content by selecting real-world locations or objects. The client receives position data indicating a position and orientation of the controller, the position data defining an axis of the controller. The client device performs ray casting to determine a location in a 3D map of a real world that intersects the axis. The client device receives a selection indication (e.g., a user pressing a button on the controller). The client device selects, subsequent to the selection indication, the location in the 3D map that intersects the axis as a waypoint. The client device defines a route for a virtual object based on the waypoint.

Systems and methods for providing a shared augmented reality environment are provided. In particular, the latency of communication is reduced by using a peer-to-peer protocol to determine where to send datagrams. Datagrams describe actions that occur within the shared augmented reality environment, and the processing of datagrams is split between an intermediary node of a communications network (e.g., a cell tower) and a server. As a result, the intermediary node may provide updates to a local state of a client device when a datagram is labelled peer-to-peer, and otherwise provides updates to the master state on the server. This may reduce the latency of communication and allow users of the location-based parallel reality game to see actions occur more quickly in the shared augmented reality environment.

Data hierarchy protocol for data transmission pathway selection
A dataflow hierarchy protocol is implemented by one or more devices to optimize how the one or more devices process datagrams for network communications. The dataflow hierarchy considers various available network pathways for dataflow. A device implementing the dataflow hierarchy selects one or more of the available network pathways to provide low latency in data communication with other devices. The device may sample various available network pathways to determine pathway metrics (e.g., latency) and select one or more network pathways based on the metrics. The available network pathways can include pathways through one or more intermediary nodes, such as pathways through a game server, pathways through a cell tower, and pathways through a network.

A message router partially decodes messages to determine how to route the messages. The message router receives a message and identifies a field of the message as a candidate field for including an envelope identifier that indicates an envelope type of the message. The envelope type of the message indicates where information, such as where to route the message, is stored within the message. The message router attempts to decode the candidate field to determine whether the candidate field includes the envelope identifier, and responsive to the candidate filed including the envelope identifier, the message router determines the envelope type of the message. The message router routes the message according to the envelope type.
A depth prediction model for predicting a depth map from an input image is disclosed. The depth prediction model leverages wavelet decomposition to minimize computations. The depth prediction model comprises a plurality of encoding layers, a coarse prediction layer, a plurality of decoding layers, and a plurality of inverse discrete wavelet transforms (IDWTs). The encoding layers are configured to input the image and to downsample the image into feature maps including a coarse feature map. The coarse depth prediction layer is configured to input the coarse feature map and to output a coarse depth map. The decoding layers are configured to input the feature maps and to predict wavelet coefficients based on the feature maps. The IDWTs are configured to upsample the coarse depth map based on the predicted wavelet coefficients to the final depth map at the same resolution as the input image.
Processing of actions within a shared augmented reality experience is split between an edge node of a communications network (e.g., a cell tower) and a server. As a result, computation of the current state may be sharded naturally based on real-world location, with state updates generally provided by the edge node and the server providing conflict resolution based on a master state (e.g., where actions connected to different edge nodes potentially interfere with each other). In this way, latency may be reduced as game actions are communicated between clients connected to the same edge node using a peer-to-peer (P2P) protocol without routing the actions via the game server.

Cloud assisted generation of local map data using novel viewpoints
An augmented reality system generates computer-mediated reality on a client device. The client device has sensors including a camera configured to capture image data of an environment and a location sensor to capture location data describing a geolocation of the client device. The client device creates a three-dimensional (3-D) map with the image data and the location data for use in generating virtual objects to augment reality. The client device transmits the created 3-D map to an external server that may utilize the 3-D map to update a world map stored on the external server. The external server sends a local portion of the world map to the client device. The client device determines a distance between the client device and a mapping point to generate a computer-mediated reality image at the mapping point to be displayed on the client device.
