Abstract:
The present invention generally provides a method of performing dynamic calibration of a stereo vision system using a specific stereo disparity algorithm adapted to provide for the determination of disparity in two dimensions, X and Y. In one embodiment of the present invention, an X/Y disparity map may be calculated using this algorithm without having to perform pre-warping or first finding the epipolar directions. Thus information related to camera misalignment and/or distortion can be preserved in the resulting X/Y disparity map and later extracted.
