ABSTRACT
This thesis details the development of an accurate and e cient wide-angle stereo
vision system. Wide-angle or sheye stereo is desired because it provides the capa-
bility to recover depth information for a large scene from a single stereo image pair.
However, nonlinear image distortions caused by the camera optics complicate the
necessary stereo processes of camera modeling and disparity analysis. The charac-
terization and removal of these lens distortions therefore is considered vital to stereo
evaluation of sheye images. Existing wide-angle stereo systems have maintained
