Method and device for monitoring motor vehicle in case of regulation violation for running red light

Abstract

The invention discloses a method for monitoring a motor vehicle in case of regulation violation for running the red light. The method includes the following steps: A. a red light signal time range is obtained, and detection of running against guiding arrows beyond the red light signal time range is conducted; B. running speed V of the vehicle in front of a stop line in the red light signal time range is detected, and if the running speed is larger than a preset value Vy, a first evidence picture of the vehicle is shot; C. whether the vehicle is pressed on the strop line is detected, and if the vehicle is pressed on the stop line, a second evidence picture is shot, a step D is conducted, otherwise, detection stops; and D. a regulation violation type of the vehicle is judged, and a third evidence picture is shot. The invention further discloses a device for monitoring the motor vehicle in case of the regulation violation for running the red light. The method and device has the advantages of being high in collecting accuracy, small in data redundancy, low in cost and capable of further determining a detailed regulation violation type and monitoring regulation violation behaviors of the vehicle running against the indicating signs during the green light.

Description

technical field [0001] The invention relates to the field of traffic monitoring, in particular to a method and device for monitoring traffic violations by running a red light. Background technique [0002] Existing monitoring schemes for motor vehicle violations of running red lights usually use a pressure-sensitive coil buried under the parking line of each lane. In the red light state, if it is within the red light time, the camera is controlled to take evidence pictures, and then the license plate number is recognized according to the evidence pictures. The disadvantage of this solution is that since only one evidence picture is taken, if the speed of the vehicle is fast, the captured picture may not contain the vehicle, resulting in insufficient evidence for taking pictures of running a red light. [0003] There is also another monitoring scheme for motor vehicles running red lights, which is to expand the shooting range of the camera, take the first evidence picture wh...

Problems solved by technology

[0006] The purpose of the present invention is to overcome the low accuracy of evidence collection, large data redundancy, high cost, inability to further confirm the specific illegal type of the vehicle, and inability to monitor the illegal behavior of the vehicle not driving according to the indicator signs when the green light is green. Insufficient, provide a motor vehicle running a red light violation monitoring method
