Research And Implementation Of Intelligent Transportation Video System Based On DM6446

IT(Intelligent Transportation)is a sunrise industry based on video and imageprocessing, at present, the national public security system all over the city thecomprehensive promotion "320 project", how to make full use of city huge imageresources for urban public security and city, which shows the intelligent transportationand prospect of commercial value has very inviting. Aiming at the intelligenttransportation system (ITS) in the field of related technologies, based on the DM6446video decoding algorithm and transplantation and optimize implementations.This paper studied the H.264 coding in the same image quality reach highercoding efficiency, while in network adaptability and anti-miscode ability is alsocarried out considering, it and intelligent video analysis unifies, can complete theurban road traffic video collection and real-time traffic video released, for urbancitizens of travel offer accurate traffic information.The thesis mainly introduces the H.264 transplantation and optimization ofvideo coding and decoding based on digital video TMS320DM6446 in TI company'shardware platform.The idea is first to compile and debug the code of H.264 in thePC,then debugging,compilation,links and optimization through the softwareplatform,ultimately load board and control the OS of ARM ,and then control the DSPprocessing and stream processing through super terminal.
