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.
