Method for detecting video traffic parameters of intersection

Abstract

The invention relates to a method for detecting the video traffic parameters of a road intersection. The method for detecting the video traffic parameters of the road intersection comprises the following steps: ROI (Region of Interest) setting, selective background modeling, accurate vehicle detection, optimization of traffic flow statistics and error detection. According to the method, the selective background modeling is adopted, and a modeling background picture has high stability and high accuracy, so that a traffic flow parameter can be calculated accurately during real-time passage of vehicles; on the basis of the selective background modeling, the accurate vehicle detection step is performed, so that detection information on whether vehicles press lines can be obtained rapidly, and traffic parameter information is obtained dynamically in real time; and moreover, the detection method is suitable for being applied to complicated environments such as intersections, and has the advantages of high stability, low error rate and high accuracy.

Description

technical field [0001] The invention belongs to the field of traffic parameter detection, in particular to a video traffic parameter detection method used at road intersections. Background technique [0002] With the progress of urbanization and the popularization of automobiles, the number of automobiles has increased sharply, and problems such as traffic congestion, frequent traffic accidents, and traffic environment deterioration have become more and more serious. The existing roads can no longer meet the needs of economic growth. In order to improve the traffic conditions and provide efficient traffic services, the Intelligent Transportation System (ITS) emerged and developed. Among them, video traffic parameter detection is widely used in Intelligent Transportation System (ITS) due to its own advantages. There are many ways to detect traffic flow parameters in common use. The traffic flow parameter detection system based on video is intuitive, easy to install, and low ...
