On the basis of object's information processing mechanism with frog's eyes, this paper discussed a bionic detection
technology which suitable for object's information processing based on frog's vision. First, the bionics detection theory
by imitating frog vision is established, it is an parallel processing mechanism which including pick-up and pretreatment
of object's information, parallel separating of digital image, parallel processing, and information synthesis. The
computer vision detection system is described to detect moving objects which has special color, special shape, the
experiment indicates that it can scheme out the detecting result in the certain interfered background can be detected. A
moving objects detection electro-model by imitating biologic vision based on frog's eyes is established, the video
simulative signal is digital firstly in this system, then the digital signal is parallel separated by FPGA. IN the parallel
processing, the video information can be caught, processed and displayed in the same time, the information fusion is
taken by DSP HPI ports, in order to transmit the data which processed by DSP. This system can watch the bigger visual
field and get higher image resolution than ordinary monitor systems. In summary, simulative experiments for edge
detection of moving object with canny algorithm based on this system indicate that this system can detect the edge of
moving objects in real time, the feasibility of bionic model was fully demonstrated in the engineering system, and it laid a solid foundation for the future study of detection technology by imitating biologic vision.
