Design of Video Collection and Processing System for Opto-electronic Target Based on TMS320DM642

Video collection and processing of opto-electronic target is an important branch for video target tracking.According to the need of actual project,a video collection and processing system of opto-electronic target is designed with TMS320DM642 processor as the core and with some simple peripheral circuit and video codic chip.The block hardware design diagram of the system is discussed,and algorithm flow diagram as well as detialed software processing algorithm is described.It is proved by experiment that this system can collect and process the video with the rate of 25 f/s.It can pick-up the spot location information of the target stably in the situation of some background interference,and output the information through synchronous serial port.
