摘要 光电目标跟踪视频的采集及处理是视频目标跟踪中一个非常重要的分支。根据项目实际需求,以TMS320DM642为核心,搭配简单外围电路及视频编解码芯片,设计了光电目标跟踪视频采集及处理系统。重点论述了系统硬件设计框图,给出了系统算法执行流程及详细的软件处理算法。经实验证实,该系统能稳定采集CCD输出的25 f/s的视频流,结合一定的处理算法,能在某些背景干扰下稳定提取目标光斑位置信息,并能将信息通过异步串行口输出。 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.
