摘 要: 以Visual C++和OpenCV为工具,通过处理低视角下单摄像头采集的视频图像序列,选用了适用于平面道路交叉口的前景检测方法。通过对OpenCV中的跟踪模板进行改进,开发出适合道路交叉口车辆运动参数检测的程序。应用卡尔曼滤波对检测到的运动参数进行处理,使得检测到的数据更加真实可靠。研究成果可应用于交通冲突理论分析和交通安全评价。
关 键 词: 交通工程;交叉口安全;视频处理;车辆运动参数检测;卡尔曼滤波

Abstract: By taking Visual C++ and OpenCV as tools and processing video image sequences gathered by one camera under low angle, suitable prospect examination method of plane intersection was selected. Through making improvement to OpenCV track template, the procedure suited to movement parameters examination of intersection vehicles was developed. The Kalman filtering was used to process movement parameter, and the detected data were more reliably. The research results could be applied in the transportation conflict theoretical analysis and traffic safety appraisal.
Key words: traffic engineering; intersection safety; video processing; vehicle motion parameter detection; Kalman filtering
