Traffic intersection monitoring technology and system based on video image analysis

Abstract

The invention discloses a traffic intersection monitoring technology and system based on video image analysis. The system comprises a network camera, a network switch, a computer processor, an output control interface, a signal lamp machine and information distribution terminal equipment. The method is characterized in that firstly, each path of camera and client side analysis software detect vehicles and traffic flows in each direction within a designated area in real time by a video image analysis technology; then, the comprehensive analysis and calculation of a server side gives an optimal signal lamp control parameter for automatically switching a signal lamp; and images of road in a abnormal situation are distributed to respective destinations. The system has the advantages that the camera used for detecting a road surface is erected in the air and the installation cost and maintenance cost are low; when a road is changed, equipment does not need to be installed again but can be flexibly and conveniently changed by software; the video image analysis technology is used for detecting the road surface, thus the observation range is large and the accuracy rate is high. The invention is suitable to control the signal lamp on the intersection and distribute images of intersections in an abnormal state.

Description

Technical field [0001] The present invention relates to a new method and system for intersection signal light control and intersection traffic monitoring, and in particular to a method and system based on video image analysis for vehicle detection in various road sections, and analysis of intersection traffic flow and signal light control. Video recognition technology in the field of traffic monitoring technology. Background technique [0002] In recent years, with the popularity of automobiles, the number of automobiles has increased rapidly, and the problems of traffic congestion and excessive carbon dioxide emissions have become increasingly serious. And ensuring the smooth flow of vehicles is one of the effective ways to alleviate these problems. For this reason, the intelligence of intersection signal light control has been widely valued. As one of the intelligent cores of signal light control, the detection and sensing technology for the presence or absence of vehicles on ...

Problems solved by technology

These technologies need to embed sensors under the road surface of each lane. Due to wear and power loss, road construction needs to be stopped for an average of 5 to 7 years, and the maintenance cost is high. In addition, the ground sense coil must be re-embedded when the road changes, which is not convenient and flexible enough. , not intuitive
