Visual object recognition systems and visual robot guidance systems, namely, recorded computer software and computer hardware for use in providing image recognition and controlling the movements of a robotic arm

Abstract

A system for generating a depth map for an object in a three-dimensional (3D) scene includes an image capture sensor and a processor. The image capture sensor is configured to capture a plurality of images of the object at a plurality of different focal planes. The processor is configured to calculate a plurality of variance values for a plurality of image locations for each image captured by the image capture sensor. The processor is also configured to determine a peak variance value for the plurality of image locations based on the calculated variance values associated with the same image location for each of the plurality of images of the object at the plurality of different focal planes. The processor is also configured to generate the depth map for the object based on the determined peak variance value for each image location and the plurality of different focal planes.

Abstract

An industrial robot system includes an end effector connectable to a robot arm, a drive assembly, and a controller. The end effector includes a distal housing, a spindle assembly rotatable about a rotational axis, a drill bit rotatable about the rotational axis, and a sensor assembly. The sensor assembly includes a first light source, a second light source, and a photosensitive array. The first light source produces a first fan of light which is projected as a first line of light on the object surface. The second light source produces a second fan of light, which is projected as a second line of light on the object surface. The photosensitive array detects a first reflection line corresponding to the first line of light and a second reflection line corresponding to the second line of light.

Abstract

Disclosed herein are embodiments and methods of a visual guidance and recognition system requiring no calibration. One embodiment of the system comprises a servo actuated manipulator configured to perform a function, a camera mounted on the face plate of the manipulator, and a recognition controller configured to acquire a two dimensional image of the work piece. The manipulator controller is configured to receive and store the face plate position at a distance “A” between the reference work piece and the manipulator along an axis of the reference work piece when the reference work piece is in the camera's region of interest. The recognition controller is configured to learn the work piece from the image and the distance “A”. During operation, a work piece is recognized with the system, and the manipulator is accurately positioned with respect to the work piece so that the manipulator can accurately perform its function.
