摘要 采用TMS320DM642作为整个系统中视频图像的核心处理单元,使用H.264压缩算法,对现场采集的车辆图像进行处理,并通过CDMA无线网络,实现图像的无线传输.在分析DM642嵌入式DSP处理器特点的基础上,阐述系统的结构组成和各个功能,实现对车辆的实时监控. Adopting the TMS320DM642 as the core unit of the whole system, the paper chooses H. 264 compression algorithm to process the the video of vehicles, and then transmits the compressed video through CDMA wireless networks. On the basis of the analyzing the functions of DM642 DSP processor, the paper introduces the system composition and the structure of the various functions.
