Video detection method of road crossing event at cross road

Abstract

Disclosed in the invention is a video detection method of a road crossing event at a cross road. The method is characterized in that a monitoring camera installed at a cross road collects a video signal; after the video is decoded, a computer vision and image processing technology is used to carry out road crossing event detection in a range of a certain distance nearby the cross road so as to identify targets of vehicles and pedestrians and the like on the road; a mutual conversion relation of an image pixel coordinate, a world coordinate, and a GPS coordinate is combined to obtain information of GPS positions, moving directions and speeds and the like of the targets and the obtained information is transmitted to a background control and dispatching center by a communication network. According to the method, the video collection device can be installed and maintained simply and easily; and economic and effective performances are realized. The detection method integrating with video processing, video monitoring, and real-time alarming is capable of carrying out determination and alarming on a road traffic state autonomously under the circumstances of unattended operation and tracking a moving object; and an integrated traffic management system with real-time, accurate, and efficient characteristics can be realized.

Description

technical field [0001] The invention belongs to the field of digital image processing and the technical field of intelligent video monitoring, and specifically relates to a video detection method for crossing a road event at an intersection. Background technique [0002] The intelligent transportation system realizes a high degree of informatization of traffic, makes full use of road resources reasonably, provides travelers with effective road condition information, disperses the traffic flow on congested road sections, and realizes the optimal flow of motor vehicles and pedestrians on the road, thus alleviating the overloading of roads. Load use, improve transportation efficiency, and establish a safe and comfortable road traffic operating environment. [0003] Traffic object detection and information collection are crucial in intelligent transportation systems. At present, the commonly used traffic detection methods at home and abroad mainly include loop coil detection, i...
