Problems solved by technology
Among them, ultrasonic waves in ultrasonic detection are easily affected by vehicles and pedestrians, resulting in low detection accuracy and relatively short detection distances.
Infrared detection will be affected by the heat source of the vehicle itself, the ability to resist noise is not strong, and the detection accuracy is not high
The detection accuracy of annular buried coil detection is high, but it is required to be installed in the civil structure of the road surface, which will damage the road surface, inconvenient construction and installation, and the number of installations is large, and the cost is high

The invention discloses a method and system for identifying abnormal road driving behaviors. The method includes: performing vehicle identification and detection on the acquired current video frame image of the road, extracting comparison information of the detected vehicle image; comparing the extracted comparison information with the completed The comparison information of each vehicle image in the video frame database is correspondingly compared, and it is judged whether the comparison result meets the predetermined threshold condition; if so, the corresponding two vehicle images are the same vehicle, and the comparison information of the corresponding vehicle image in the completed video frame database is updated ; If not satisfied, the current comparison information is stored in the completed video frame database; the direction of motion of each vehicle is obtained according to the position information of each vehicle image in the completed video frame database; the direction of motion of each vehicle is compared with the set driving direction Or the driving direction represented by the extracted lane line is compared to determine the reverse driving vehicle; real-time monitoring of the current road violation driving behavior, reducing traffic pressure and preventing accidents.
Description
technical field [0001] The invention relates to the technical field of image processing, in particular to a method and system for identifying abnormal road driving behavior. Background technique [0002] At present, there are many methods for road abnormal driving detection, mainly ultrasonic detection, infrared detection, annular buried coil detection and so on. Among them, ultrasonic waves in ultrasonic detection are easily affected by vehicles and pedestrians, resulting in low detection accuracy and relatively short detection distances. Infrared detection will be affected by the heat source of the vehicle itself, the ability to resist noise is not strong, and the detection accuracy is not high. The detection accuracy of annular buried coil detection is high, but it is required to be installed in the civil structure of the road surface, which will damage the road surface, inconvenient construction and installation, and the number of installations is large, and the cost is...
