Research on Vehicle Track Algorithm Based on the Integration of Video Vehicle Detector

以德州仪器公司的达芬奇平台TMS320DM6446芯片为核心,对系统硬件各个主要模块进行分析设计,构建了一个一体化视频车检的硬件系统,最后选择现场能见度比较低的场合进行算法设计和实验。实验结果表明,该一体化车辆视频检测系统具有良好的检测效果,能够实现交通场景中的车辆检测计数,车辆跟踪、车辆定位等功能,为交通流诱导系统提供真实可靠的数据。

Integrated video vehicle detector based on DaVinci technology,has the advantages of compact structure,lower power ,faster than video vehicle detector currently in use.In this paper, TMS320DM6446 chip of TI’ s DaVinci platform was used as a core. We analyze major modules of hardware system, building an integration hardware system of vehicle video detection. Finally, we select the relatively low visibility situations to algorithm design and experiment,the experimental results show that,the integration of vehicle video detection has good detection results, which can realize vehicle detection and counting, vehicle tracking, vehicle positioning and other functions in traffic scene,and provide reliable data for traffic flow guidance system.
