Video detecting method aims at vehicles which enter into jammed intersection by force

Abstract

The invention discloses a video detecting method aims at vehicles which enter into a jammed intersection by force. The video detecting method includes the following steps. A state of an overflow detection area of an intersection ahead is monitored based on obtained video image data. Positions and dwell time of all vehicles shown in the video image data are tracked and recorded in a real time mode. When the state of the overflow detection area is a vehicle overflowing state, vehicles which exceed a parking line of a vehicle detecting area are labeled as suspected peccant vehicles. A traffic state of the current road is confirmed based on the obtained video image data. When the traffic state of the current road is a jammed state, the suspected peccant vehicles which reach peccancy standards are labeled as peccant vehicles. In terms of each peccant vehicle, multiple images which represent a peccancy process of the peccant vehicle are extracted from the obtained video image data. With the video detecting method, peccant vehicles which enter into a jammed intersection by force can be effectively photographed.

Description

technical field [0001] The invention relates to the technical field of intelligent traffic monitoring of video processing technology, in particular to a video detection method for motor vehicles entering forcibly when intersections are congested. Background technique [0002] Article 53 of the "Regulations for the Implementation of the Road Traffic Safety Law" stipulates: When a motor vehicle encounters a traffic jam at an intersection ahead, it shall stop outside the intersection and wait in turn, and shall not enter the intersection. But in the actual traffic situation, when the traffic signal light ahead is a green light, but when serious congestion has taken place on the road ahead, there will still be vehicles that continue to drive into the intersection in violation of regulations. These vehicles cannot enter the road ahead due to the congestion ahead, and will still stay in the middle of the road when the traffic signal changes to a red light, so that vehicles in the ...

Problems solved by technology

The limitation of this solution is that the traffic flow is used to judge whether the current intersection is congested. The result of the judgment is relatively vague and reliable, and false alarms are prone to occur.

In addition, when the road is really congested, the feasibility of obtaining the vehicle trajectory by extracting vehicle shape and texture features for vehicle tracking is low. With the backlog and occlusion of vehicles on the road, it is very easy to cause false positives caused by feature failure. and false alarms, it is impossible to accurately capture the picture of the corresponding position of the vehicle, and the result of effective illegal punishment cannot be achieved, and the actual application effect is not ideal
