Abstract
The present invention is embodied in a system and method for computing rectifying homographies for stereo vision processing of three dimensional (3D) objects. In general, the system and method of the present invention computes 2D projective transforms or homographies derived from specialized projective and affine transforms or components. The affine transform is comprised of a similarity transform and an optional shearing transform for image rectification. During image rectification of the present invention, optimization techniques are used for reducing the distortion.
