Red light overriding detection system and method based on digital video camera

Abstract

The invention relates to a digital camera-based detection device and method for running a red light. The invention adopts a high-resolution digital camera for road monitoring. The red light detection device mainly includes front-end equipment and ground equipment. The digital camera (1) in the front-end equipment collects images of intersections, and the images are sequentially transmitted through the front-end optical transceiver (2), optical fiber (6), and ground optical transceiver (10) in the ground equipment. Give the industrial computer (9). The industrial computer judges the behavior of the vehicle according to the set detection parameters and the current signal light status. Extract information from vehicles running red lights, obtain information such as vehicle licenses, store and manage information such as picture sequences or video streams before and after crossing the line, and the vehicle's license plate. The invention can monitor the two-lane vehicles in the same direction only by using a high-resolution digital camera, without setting up a separate panoramic camera to photograph the signal light state, so that the detection system is more powerful in judging and enforcing violations.

Description

technical field [0001] The invention relates to a red-light detection device and method based on a high-resolution digital camera (with a resolution above 1280*1024), which uses a high-resolution digital camera for road monitoring and is an automatic video detection method. Background technique [0002] Under the existing technology, it is very popular for the traffic control department to use video means to monitor roads. These methods generally collect road traffic conditions through cameras, transmit the acquired image information to the remote control center, and perform manual monitoring through the display of the monitor; and can Process the images acquired by the camera to obtain road traffic conditions (such as traffic volume, vehicle speed, etc.). For illegal vehicles such as running red lights, it is necessary to obtain clear vehicle pictures through several cameras or cameras installed at the intersection pointing to each lane, and combine the pictures obtained by...

AI Technical Summary

Problems solved by technology

[0004] One is high cost

In one direction of an intersection, at least one panoramic camera and close-range cameras or cameras equal to the number of lanes must be installed in order to perform red light detection without missing any blind spots, and the system cost is high

[0005] Second, there are loopholes in law enforcement

Since the license plate information of the violating vehicle cannot be identified in the panoramic camera, there are only clear pictures of the vehicle license plate provided by the close-range camera or the camera, which proves that the violating vehicle in the picture taken by the panoramic camera and the vehicle in the license plate picture are the same vehicle. legal laxity
