摘要
模仿昆虫复眼结构形状,设计了一种仿生复眼测量系统。该系统由七个CCD摄像机按照复眼最小单元排列组成,利用多个DSP处理板对七路视频信号进行同步处理,模拟实现了复眼的功能。与传统的视觉测量系统相比,该系统具有更宽的视场和更高的运动灵敏度。本文利用改进的相关性方法实现视频图像的拼接,生成全景图,并提出了新的方法,较好地消除了因图像局部不齐和图像灰度不一致带来的人为拼接痕迹。
Imitating the structure and shape of compound eye of insects, a bionic compound eye measurement system is designed. It is similar to the smallest cell of compound eye and composed of 7 CCD cameras. Several DSP processors are used to process 7 video signals synchronously to simulate the functions of compound eye. Comparing with the traditional vision measuring system, the bionic compound eye system designed has larger view and higher motion sensitivity. The improved relativity method is used to joint the video images to make a panoramic image. It has advantage of eliminating artificial connecting mark preferably caused by differences in local image coordinate and gray level.
