Problems solved by technology

This method also has obvious deficiencies: (1) The installation of the system needs to slot the road surface to embed the coil, which destroys the road surface to a certain extent and affects the life of the road surface; Damaged by factors, maintenance is not convenient enough
This method has obvious disadvantages in practical applications: (1) it is very blind t

specific Embodiment approach

[0030] Such as figure 2 As shown, a high-definition camera is deployed on the side of the intersection. The camera has a resolution of more than 2 million, and the field of view can cover 2 to 3 lanes. The field of view of the camera should be able to clearly distinguish the traffic lights at the intersection, the zebra crossing on the opposite road, the intersection and your own side. Stop line area. The video violation processing device is connected with the camera, and is used to detect and record violations of motor vehicles running red lights.

[0031] Obtain high-definition video stream data from the camera to analyze violations of red light violations, such as image 3 . Digital image processing is first performed on the input high-definition video stream, such as underexposure of the camera, which can enhance the overall brightness of the image. Each image is analyzed through target detection and target tracking algorithms to obtain the driving trajectory of...

Abstract

The invention belongs to the technical field of intelligent traffic management, in particular to a motor vehicle red light running rule violation evidence obtaining method based on high-definition videos. According to the method, a high-definition camera is adopted for shooting videos, and the vehicle behavior track is analyzed according to the target detection and tracking technology of the video contents. The red light running behavior is detected under the red light phase of traffic lights, effective rule violation high-definition images are obtained after the red light running rule violation is confirmed, two red light running evidence obtaining pictures conforming to the national standard (GA/T832-2009) are formed, and in addition, video stream recording the whole red light running rule violation process is synthesized into the evidence obtaining videos. Finally, the evidence obtaining results are transmitted to a management system of a law-enforcing department through network. When the method provided by the invention is adopted, the operation completely conforms to the national standard of the red lamp running automatic recording system, and in addition, the customized expansion can be carried out for different cities. Compared with the exiting red light snap-shot technology, the method provided by the invention has more efficient recoding effectiveness and higher catching rate.

Description

technical field [0001] The invention belongs to the technical field of intelligent traffic management, and in particular relates to a high-definition video-based method for obtaining evidence for a motor vehicle running a red light. Background technique [0002] Motor vehicle running a red light refers to the behavior of a motor vehicle crossing the stop line and continuing to drive when it corresponds to the phase of the red light. The red light automatic recording system is a system for uninterrupted automatic detection and recording of motor vehicle red light running behavior at intersections and road sections with traffic signal control, and it is an important part of the intelligent traffic system (ITS). It is a comprehensive system integrating visualization technology, image processing technology, automatic control technology, computer communication technology and database management technology. It can record and take pictures of violating motor vehicles, provide traf...
