高速公路车辆违章超速行为检测与判别的研究

违章超速是造成高速公路交通事故的重要原因之一,其造成的事故后果相当严重。文章针对高速公路上车辆违章超速行为,研究了一种基于虚拟视频检测线的违章超速行为检测与判定的实用算法。该算法考虑到采集卡的采集频率,分析了检测线的设置对检测精度的影响,叙述了检测算法的检测与判别流程,对最高检测车速进行了理论计算,并对误检情况进行了快速恢复技术研究。通过课题实验验证该算法具有良好的适应性和较高的检测率。

Research on Detection and Judgment of Peccant Overspeed Behavior of Vehicles in Expressway

Peccant overspeed behavior is one of the most important reasons of traffic accidents in expressway,which can cause very severe results.As to the peccant overspeed behavior of vehicles in expressway,this paper studies a detection and judgment arithmetic of peccant overspeed behavior based on virtual video detection lines.Considering the capture frequency of video capture card,the arithmetic analyzes the precision affected by the setup of detection line,introduces the detection and judgment process,and calculates the highest speed of detected vehicles.At the same time,the article also researches on the fast recovery technique under wrong detection situations.The result tested by subject experiment shows better adaptability and higher detection rate.
