基于视频的高速公路测速系统

Expressway Vehicle Speed Measurement System Based on Video

文章介绍了基于视频的车辆测速管理系统,并提出了一种车辆的测速方法。车辆测速管理是智能交通系统(ITS)中的一个重要组成部分,它集牌照识别、测速检测、流量监控、费用收取等多项功能于一体,主要用于对高速公路超速违章车辆的监控。在车辆的测速原理中,指出从相邻视频帧图像中获取车辆的"像速度",并间接获取车辆实际速度的方法。从而为高速公路测速管理系统的关键点提出了一种切实可行的解决办法。

This article describes a vehicle speed measurement system based on video, and proposed a method for vehicle speed. Vehicle speed management plays an important role in Intelligent Transportation System （ITS）. It contains license plate recognition, speed detection, traffic monitoring, fees charged and other functions, mainly used for vehicle monitoring highway speeding violation. In the principle of vehicle speed measurement, this paper pointed out a method that obtain the vehicle＆#39;s ＆quot;pixel speed＆quot; from the adjacent frame images, and indirectly got the actual speed of the vehicle, thus presenting a practical solution to the critical point of the expressway speed management system.
