摘　　要：基于TMS320DM642,采用ADV7171&ADV7181视频编解码芯片,设计了嵌入式可见光图像识别系统.着重研究并对比分析了视频编解码芯片的选型,拓展了类似的视频系统的视频编解码芯片的选型范围,简要分析了系统构架,并详细分析了各功能模块,研究了在实际设计与实现中遇到的问题并给出了相应解决方案,给出了主要模块的原理图.最后介绍了系统的功能扩展及应用前景.The embedded visible-light video image identification system is designed using ADV7181 ＆ADV7171 for digital video encoder/decoder based on TMS320DM642. The selected version of digital video encoder/decoder is emphatically analyzed in the comparative method, to expand the choice range of the digital video encoder/decoder of similar video systems. The architecture of this system and its function modules are analyzed. The problems occurred in the practice design and implementation process are studied and some solu- tions are given, and the schematic diagrams for the main parts are also given out. Lastly, it points out the possible improvements and the application foreground of the system.
