Intersection vehicle illegal lane change early warning management and control method and system based on thunder monitoring

Abstract

The invention discloses an intersection vehicle illegal lane change early warning management and control method and system based on thunder monitoring, and the method comprises the steps: tracking and monitoring the lane vehicle motion information of a to-be-monitored intersection through a multi-target radar from an opposite intersection position of the to-be-monitored intersection; acquiring vehicle motion video image information of each lane within the solid lane line from a position above the to-be-monitored intersection by using a video monitor; marking a vehicle with an abnormal track as a target vehicle by using the tracked and monitored vehicle motion information and the obtained vehicle motion video image information of each lane; and obtaining vehicle information of the target vehicle from the vehicle motion video image information. According to the method, the problems that in the prior art, a fixed monitoring camera is single in detection mode and direction, only vehicles which change lanes illegally at an intersection in front of the monitoring camera can be recognized for evidence obtaining, pre-judgment and recognition in advance cannot be achieved, and pre-warning management and control cannot be conducted on illegal lane changing behaviors are solved.

Description

technical field [0001] The present invention relates to the technical field of management and control of vehicles illegally changing lanes at intersections, in particular to a method for early warning management and control of vehicles illegally changing lanes at intersections based on Levision monitoring. Background technique [0002] With the continuous and rapid increase of the number of cars in our country, more and more cities are facing road traffic problems. Among them, the illegal lane changes of vehicles during the morning and evening peak hours not only seriously reduce the traffic efficiency of urban road intersections, but also disrupt the traffic order. It is also very easy to cause accidents and become one of the main reasons for urban traffic congestion. [0003] However, the fixed monitoring camera detection method and direction in the existing technology are single, and can only identify and obtain evidence for vehicles that illegally change lanes at the int...

AI Technical Summary

Problems solved by technology

[0005] In view of the above-mentioned technical problems, the purpose of the present invention is to overcome the single detection method and direction of the fixed monitoring camera in the prior art, which can only identify and obtain evidence for vehicles that illegally change lanes at intersections in front of the monitoring camera, and cannot achieve pre-judgment and recognition in advance. And the problem of early warning and control of illegal lane changes, so as to provide a comprehensive and accurate identification of vehicle illegal lane changes at intersections during use, and can also be pre-judged and identified in advance to prevent illegal lane changes Behavioral early-warning management and control to ensure smooth and safe intersection traffic. A method and system for early warning management and control of illegal lane changes at intersections based on Levision monitoring
