Abstract: A new type of binocular stereo Omni-Directional Vision Sensor (ODVS) is designed, in which the mirror of catadioptric is designed by using secondary catadioptric imaging principle. Then solution of the catadioptric mirror is obtained by the fourth order Runge-Kutta algorithm. Finally the two ODVS with the same parameters of the average angle becomes a binocular stereo ODVS which is composed by back-to-back manner. To avoid conversions of coordinates during three-dimensional measurement and reconstruction, Gaussian coordinates is used during the processing of the video data capturing, information processing and presentation. ODVS can align the azimuth of feature point easily. Through this character, ODVS can simplify camera calibration, feature points matching, and other cumbersome steps easily. The results of experiment show that the device can simplify computing complexity of three-dimensional visual measurement and facilitate three-dimensional image matching.


Keywords: Stereo vision, ODVS, Average angle resolution, Stereo image matching
