视频移动侦测技术在城市交通管理中的应用

针对城市交通管理中的交通红绿灯计算机监控系统采用地埋感应线圈来识别红灯禁行区车辆的缺陷,描述在该计算机监控系统中如何采用视频移动侦测技术(VMD),取代地埋感应线圈来识别道路红灯禁区中行使的车辆,减少安置地埋线圈时对路面造成的损坏.分析应用该技术的可行性,硬件的可实现性.阐述如何通过计算机程序荻取摄相机自动抓拍的交通红绿灯路口上行驶的机动车的违章行使照片和道路交通状况信息的方法.

An application of video motion detection technology in city traffic management

For city traffic management,an underground induction winding is used to identify vehicles inside the red light forbidden zone in most computer monitoring systems at traffic lights.We described how to apply video motion detection(VMD) technology in these computer surveillance systems instead of underground induction windings.Using VMD eliminates the underground induction windings that damage road surfaces.The possibility of applying and implementing VMD technology with supporting hardware was analyzed.We described how to develop the program to record automatically those vehicles that violate traffic rules at traffic lights,and to obtain the traffic status of and evidence about those vehicles.
