METHODS AND SYSTEMS FOR PARKING ZONE MAPPING AND VEHICLE LOCALIZATION USING MIXED-DOMAIN NEURAL NETWORK WITH ALTITUDE COMPENSATION
Methods and systems for assisting a vehicle to park using mixed-domain image data. Image-domain data is generated based on raw image data received from a plurality of cameras mounted on a vehicle. A bird's-eye-view (BEV) image is generated based on the raw image data. BEV-domain data associated with the BEV image is generated, which includes data associated with parking landmarks in the parking zone. A tri-perspective view (TPV) and associated data can be generated. A computing system localizes the vehicle within the parking zone based on the BEV-domain data, the image-domain data, and the TPV-domain data to generate localization data. The computing system performs mapping of the parking zone based on all three image-domain data and the localization data. A motion sensor such as an inertial measurement unit (IMU) can generate data that is used to compensate the various domain data.
A method includes obtaining image frames from each camera disposed along a vehicle, where each image frame corresponds to a same timestamp. The method further includes constructing a first birds-eye view (BEV) image from each image frame with a first BEV module and constructing a second BEV image from each image frame by Inverse Perspective Mapping (IPM) with a second BEV module. The first BEV module extracts features of an external environment of the vehicle from each image frame, transforms the features to a three-dimensional space, and projects the three-dimensional space onto an overhead two-dimensional plane. Subsequently, a merging module merges the first and second BEV images to produce a hybrid BEV image. Features of an external environment of the vehicle within the hybrid BEV image are detected by a deep learning neural network and the hybrid BEV image is displayed to a user in the vehicle.

The invention relates to a vehicle device (1 ) comprising a housing (2), in which at least one printed circuit board (7) is arranged, and comprising a fan (3), which is arranged outside the housing (2), and with an electric cable (11), which is laid through a cable opening (13) in the housing (2) and extends outside and inside the housing (2), wherein the cable (11 ) is connected to electric connection (9) of the fan (4) and which is connected to the printed circuit board (7), wherein the cable (11) outside the housing (2) is arranged on a guiding element (12) arranged adjacent to the cable opening (13), and is laid bent by the guiding element (12) of the vehicle device (1) towards the cable opening (13), wherein the cable opening (13) is arranged at a height position viewed in the height direction (y) of the vehicle device (1), which is higher than a lowest point (14) of the guiding element (12) contacted by the cable (11).
According to a method for automatic visual perception, first feature maps (17) are generated from a camera image (7) by a first encoder module (11) of a neural network (6) and the first feature maps (17) are transformed into a top view perspective. An ultrasonic pulse is emitted into the environment and an ultrasonic sensor signal (8) is generated depending on reflected portions of the emitted ultrasonic pulse. A spatial ultrasonic map (9) is generated depending on the ultrasonic sensor signal (8) and second feature maps (22) are generated from the ultrasonic map (9) by a second encoder module (12) of the neural network (6). The transformed first feature maps (20) and the second feature maps (22) are fused and a visual perception task is carried out by a decoder module (15a, 15b, 15c) of the neural network (6) depending on the fused feature maps.
