Electronic identification method of violation behaviors at traffic intersection

Abstract

The invention relates to an electronic identification method of violation behaviors at a traffic intersection. The electronic identification method includes shooting an area in through lane direction at the traffic intersection by the aid of a CMOS (complementary metal oxide semiconductor) visual sensor so as to obtain an image of the straight direction; adopting a detection zone image segmentation machine to segment a detection zone image from the straight-direction image within a preset red-light period in the through lane direction; employing a vehicle image segmentation machine to segment a moving vehicle image from the detection zone image; by the aid of a counter, calculating frame number of the moving vehicle image within the preset red light period; on the basis of the counting result of the counter, employing an embedded processor to determine whether or not a vehicle runs the red light within the preset red light period. The electronic identification method further includes adopting an image sharpening processor to perform defogging so as to eliminate influence of the hazy weather to the image. According to the arrangement, even under the hazy weather, electronic detection precision of the vehicle violation behaviors is guaranteed.

Description

technical field [0001] The invention relates to the field of electronic detection, in particular to an electronic identification method for traffic crossing violations. Background technique [0002] Running a red light is one of the most dangerous road traffic safety hazards, and has the following hazards: 1. When running a red light, the driver's attention is all on the traffic signal lights, and he cannot fully and correctly perceive the changes inside and outside the car, which will affect the driver's response and measures. 2. When running a red light, the speed of vehicles passing through the intersection is usually faster, which weakens the driver's cognitive ability to space; 3. When running a red light, the driver's ability to judge various traffic environments is reduced, which sometimes makes the driver 4. The intersection is the meeting point and conflict point of traffic flow. Running a red light increases the unsafety of the meeting point and conflict point itse...

AI Technical Summary

Problems solved by technology

The current detection method for running a red light is to use an ordinary camera to capture images, image recognition and license plate recognition of vehicles that are still passing through the intersection during the red light period, so as to provide the road traffic management department with information on illegally driving vehicles. This method is not accurate and has a single judgment rule , it is easy to cause misjudgment, which will bring economic losses or traffic inconvenience to law-abiding drivers. At the same time, this method is easily affected by haze weather
