摘　　要：宽视场图像在视频压缩、虚拟现实和传输等领域有着广泛的应用。虽然利用广角镜头也可得到宽视场图像,但广角镜头的边缘会产生难以避免的扭曲变形。为了在普通成像系统的基础上获得宽视场图像,产生了图像拼接技术。分析了双路视场拼接系统的光学及机械原理,讨论了基于相位相关的视场拼接算法优劣,提出了建立基于SOPC的双视场拼接思想,介绍了双视场拼接系统的设计与实现。Wide-field images have been widely applied in many areas, such as video compression, virtual reality and transportation science. Even though people can obtain wide-field images through wide-angle hens, the lens will inevitably engender torsional deformation. This paper analyzes the Optical and mechanical principles of panoramic mosaic camera and discusses the advantages and disadvantages of phase correlation algorithm based on such extraordinary circumstances. It also puts forward the idea of view mosaic. Finally the design and implementation of panoramic mosaic camera are introduced.

关 键 词：视场拼接 SOPC 傅里叶算法
