摘要
如何有效去除背景、消除按车道开固定窗检测车辆的方法中,由于车辆换道或相邻车道的车辆部分覆盖了被检测车道检测窗而引起的误检,是车辆检测系统需要解决的一大难题。针对上述问题提出了一种基于视频的改进的帧差法,在检测带内由车辆信息生成数据流,根据数据流的变化进行车辆检测、计数并估计平均车速。从而实现对过往车辆的准确计数,更可靠地收集各车道的车流信息,为智能交通提供实时交通参数。
How to remove the background , to eliminate the misdetection caused by vehicle changes road or it covers the detection window of the road detected partly, is a big problem to be handled in vehicle detection system.This paper presents an improved frame-difference method based on Video,and describes how to detect and count vehicles in detecting zone dynamically.With this method, we can count the vehicles passing by accurately, collect the traffic flow of each roadway reliably.We provide real-time traffic parameters for the ITS.
