Abstract
Depth imaging methods and systems with edge and baseline angle correction are disclosed. The system includes an angle-sensitive optical encoder and an image sensor disposed behind the encoder and having orthogonal pixel axes. The system captures image data including two images representing two scene viewpoints separated from each other by an encoder-defined baseline that is obliquely offset relative to a nominal baseline direction parallel to one of the pixel axes. The method can include steps of identifying an edge present in the two images; determining an angle of the edge; determining a parallel disparity, measured along one of the pixel axes, between the edge as viewed in each of the two images; and determining depth information about the edge based on the parallel disparity, the edge angle, and calibration data relating vectorial disparity information to object distance and edge angle information.
