摘　　要：单视点折反射全景成像系统存在成像透镜昂贵或安装精度要求高等不足,本文结合抛物反射面和常规成像相机实现了一种无需昂贵的远心透镜且安装精度要求不高的多视点折反射全景成像系统,并对其视点分布情况进行了分析,在此基础上,设计了视点分布较为集中的系统结构,使得成像系统拍摄的环状全景图像可以基于传统的单视点柱面展开方法进行近似展开得到效果良好的近似柱面全景图像。A single viewpoint catadioptric omnidirectional imaging system has some deficiencies, such as requiring expensive imaging lens or high precision installation, and so on. A multi-viewpoint catadioptric omnidirectional imaging model was proposed using paraboloidal reflecting mirror and conventional digital camera without expensive teleeentric lens and high precision installation. The viewpoint loci of this model was analyzed and then the multi-viewpoint catadioptric omnidirectional imaging system was designed to make the viewpoint loci more concentrated, so cricoid panoramic image shot by this system may be approximately transformed into cylinder panoramic image according to conventional single cylinder unwrapping algorithm.
