ABSTRACT:
A range finding apparatus includes a pair of spaced apart cameras which provide signals that are digitalized, stored in frame buffers, and provided to a computer that provides a range map of a target object viewed by the cameras. The computer optimizes a disparity function by minimizing a cost functional, thereby finding the range at different points on the surface of the target object based on variations in illumination, reflectivity, and texture.
