Design Of Omni-directional Vision System And Research Of Image Processing

The viewing field of traditional vision environment perceptual system is limited. As in one hand, the append of a nest of servo system in order to lock in target will increase the whole system's volume and weight thus lower the efficiency. In the other hand, traditional vision environment perceptual system can only grasp local viewing field information of surrounded environment at one time while most of viewing field information has been abandoned. The limitation of viewing field can't afford all-oriented decision-making information. Panoramic vision environment perceptual system's imaging viewing field is bigger than hemispherical viewing field (360°×180°), and can even be close to spherical viewing field (360°×360°), its technical advantage is obvious. This paper did mainly research in panoramic vision environment perceptual system.The paper firstly expatiated some correlative optical knowledge related to panoramic vision, based on which the paper discussed panoramic vision imaging theory deeply and attained several applicable panoramic reflector curve.On the foundation of this, the paper designed a hyperboloid reflector based panoramic vision system and put it into practice, and designed a scheme on specified problems of hyperboloid reflector and panoramic vision system.The paper put emphasis on research of image revert arithmetic of panoramic vision system and proposed several practicable arithmetic and compared them on the operation speed and fidelity.In the end, the paper applied time difference method in the research of target tracking technology of panoramic vision system under the lab environment and did the experiment of single-target and double-target tracking successfully.
