Traffic violation detection method based on video tracking and pattern recognition

Abstract

The invention discloses a traffic violation detection method based on video tracking and pattern recognition, and belongs to the technical fields of image recognition and pattern recognition. The method comprises the following steps: firstly, defining violation modes, namely defining traffic light stop lines, driving directions, and areas and directions of violation of course change; secondly, monitoring and controlling a camera to shoot video images of intersections; and thirdly, analyzing the video by an embedded system, performing detection and measurement by a pattern recognition method, using the video to track and acquire running tracks of vehicles, using the pattern recognition method to analyze behaviors of any one vehicle according to the running tracks, and immediately shooting the vehicle for recording if one of the following violation behaviors happens: going in wrong directions, violation of full line course change and running of a red light. A detection device used comprises a high-speed camera, a video controller, and a video tracking and pattern recognition device, wherein the video tracking and pattern recognition device comprises a traffic light signal receiving device, a video acquisition and conversion module, a violation setting module, a vehicle detection module, a video tracking module, a violation analysis module, a camera control module and a data wireless transmission module.

Description

Technical field: [0001] The invention relates to a traffic violation detection method based on video tracking and pattern recognition, and belongs to the technical field of image recognition and pattern recognition. Background technique: [0002] With the development of my country's economy, the number of automobiles has increased greatly, and traffic accidents have occurred more and more frequently. Most traffic accidents are caused by traffic accidents, especially serious violations such as running a red light, changing lanes illegally, and going the wrong way. Endangering the safety of people's lives and properties, causing the country to suffer unnecessary heavy economic losses. Therefore, the monitoring of these behaviors has great practical significance. [0003] The current detection of these traffic violations in our country is the induction coil technology, that is, the induction coil is buried at the traffic intersection, and the camera is triggered by the induct...

Problems solved by technology

However, there are two major defects in this type of technology. One is the lack of video tracking technology and pattern recognition technology. It can only capture red light running behaviors based on traffic light signals, and cannot capture retrograde and solid line lane changing behaviors. The applicability is low; The accuracy of the shooting range of the camera has high requirements, and its shooting range is defined between two stop lines. If the shooting range is expanded, such as crossing the stop line, there will be a high probability of accidental shooting, and those who did not run through the red light will be thrown away. Car calculations come in, and the implementation of technical construction is very difficult
