Abstract


Based video and image processing in intelligent transportation system is a sunrise industry , the national public security system in cities around the general promotion of the \prospects and commercial value have been very attractive . In this paper, the related technologies in the field of intelligent transportation systems (ITS) , research -based the DM6446 video codec algorithm and the transplantation and optimized implementation . In this paper, to achieve higher coding efficiency of H.264 encoding in the same image quality , also were taken into account at the same time in the network adaptation and error resilience capabilities , combined with intelligent video analysis , completion of urban road traffic flow video capture and real-time traffic video release provide accurate traffic roads , urban public travel information . This paper describes the hardware platform based on TI 's TMS320DM6446 digital video processing chip , the H.264 video codec porting and optimization process . The idea of the paper is the first H.264 code and video processing code to compile and debug on the PC , and then through the the algorithm portable software platform debug , compile, link , and optimize the final load board , ARM operating system control via HyperTerminal , and then control the DSP processing video stream processing .
