| Abstract: | Some important theoretical issues of catadioptric omnidirectional systems for the spherical mirror are researched. The projection model of the spherical system and its vertical angle of field-of-view are deducted. A back-projection unwarp algorithm of omnidirectional images are developed. An experimental system is set up which is used to verify the significance of the spherical system. |
