| 摘 要： | 为了获取整个球面全景图像,提出了全方位视觉传感器(omni-directional vision sensor,ODVS)的二次折反射的成像原理并设计了折反射镜面.利用4阶Runge-Kutta算法求得了镜面曲面的数值解,通过组合镜头的设计实现ODVS与广角镜头的集成以消除ODVS的固有死角,然后,将两台无死角的ODVS装置以背靠背的方式进行连接,并将所获取的全景视频图像进行展开及无缝拼接得到360°* 360°视频图像.实验结果表明,所设计的ODVS装置可以获取全球面的视场范围,在视频监控领域有重要的应用价值.

| Abstract: | In order to obtain a panoramic image with a full sphere view,this paper presents the two-catadioptric imaging princi- ple of omni-directional vision sensor(ODVS),by which catadioptric mirrors can be made .The reflectors curvilinear nu- meric solutions of the catadioptric mirrors are obtained by means of the fourth order Runge-Kutta algorithm.the problem of dead angle existing in current ODVSs is solved through designing the combination lens,in which ODVSs and wide-an- gle lens are put together.In addition,t... |
