A Cylindrical Virtual Space Based Catadioptric Real-time Panorama Imaging System

摘要

Since it has small field of view and only records the light intension of scene, the regular optical imaging system is short of immersion and stereo vision. The needs for stereo apperception and recurrence of large field of view scene are emerging due to the development of robot navigation technology and virtual reality technology. Some panoramic stereo imaging technologies have been developed under the drive of optoelectronics and computer vision and graphics. In this paper, a new method to construct cylindrical image-based virtual space (IBVS) automatically with smooth quadric convex curved mirror catadioptric imaging is proposed, and the projection transformation with conic reflection surface and telecentric lens is described in detail. The method to transform pixel point at image plane taken by camera into field of view image along gaze direction in cylindrical IBVS is given. The prototype instrument of system is designed, and its hardware implementation is given. The experiment result shows that the instrument can construct real-time IBVS that has wide field of view and better imaging effect. The method would enhance the capability of surveillance and reconnaissance and self defense in battlefield
