摘　　要：针对某型导弹指令检测系统的需求,设计了基于SOPC(system on a programmable chip)的视频采集处理系统。本系统通过装备预留的视频采集口进行视频采集,然后对采集到的视频进行弹标的提取,并进行视频压缩存储以便实现视频的回放。重点介绍了基于SOPC的视频采集系统设计方案和图像预处理算法的FPGA实现。经过仿真分析,设计的系统可以实现视频采集功能,并能够实时地提取弹标。According to requirements of instruction detection system of certain missile, a video ac- quisition and processing system is designed based on SOPC （system on a programmable chip）. The sys- tem collects video from reserved ports of the equipment, then distills the information of the missile target from the collected videos, and finally compresses it to store to realize the video playback. The design scheme of the video collection system is mainly introduced based on the SOPC and the method of image preprocessing algorithm for FPGA implementation. Simulation verifies that the designed system c realize video collection function and real-time extract the information of the missile target.
