Method and system for detecting illegal left-and-right steering of vehicle at traffic intersection

Abstract

The invention provides a method and a system for detecting illegal left-and-right steering of a vehicle at traffic intersection. The method comprises the following steps of: decoding monitoring video streaming in real time from the traffic intersection so as to obtain a video image; distinguishing vehicles passing through the traffic intersection and detecting the moving trails of the vehicles; and presetting at least one virtual position on a steering lane of the video image so as to judge that the vehicle has illegal steering when the steering is not allowed by a signal lamp at the traffic intersection and the moving trail of the vehicle passes through the virtual position. According to the invention, by adopting the method for intelligently analyzing the video, the virtual loop is drawn on the monitoring video, the moving trail of the vehicle is tracked and analyzed through characteristics, and whether the vehicle has illegal steering is judged through the preset virtual loop so as to reduce the workload of manual check and control; and simultaneously, as the touch capture is achieved through the video virtual loop, the way that an induction loop is embedded in a pavement in the traditional technology is avoided, and the pavement does not need to be dig.

Description

technical field [0001] The invention relates to the field of intelligent transportation, in particular to a method and system for detecting left and right illegal steering of a vehicle at a traffic intersection. Background technique [0002] With the rapid development of national highway traffic construction and the popularization of motor vehicles, the incidents of traffic violations are increasing year by year, especially the violations at crossroads are becoming more and more serious, which poses a great threat to people's lives and safety, thus causing The traffic department attaches great importance to it and invests a lot of manpower and material resources in the monitoring of intersections. However, the frequent occurrence of such incidents has brought enormous pressure to the traffic department and put forward higher requirements. In order to solve these prominent problems, methods such as speeding up the information construction of motor vehicle monitoring, improvin...

Problems solved by technology

[0005] In order to overcome the problem that the traditional ground induction coil can only trigger and capture the vehicle, but cannot track the process of the vehicle, and needs to excavate the road surface, which affects the city appearance, the present invention provides a method and system for detecting illegal steering of vehicles at traffic intersections , adopt the method of intelligent video analysis, draw a virtual coil on the surveillance video, analyze the trajectory of the vehicle through feature tracking, and detect whether the vehicle has passed the preset virtual coil to determine whether the vehicle has turned illegally, reducing the workload of manual inspection and control; At the same time, due to the triggering and capturing of the vehicle through the video virtual coil, it avoids the way of traditional technology to bury the induction coil on the road surface, and does not need to dig the road surface
