Video-based method for detecting violation lane-changing incident of vehicle

Abstract

The invention discloses a video-based method for detecting a violation lane-changing incident of a vehicle. The method mainly comprises the steps of: separating a target background in each frame of image in video to be treated through block-based binarization segmentation, selecting a block-based characteristic angular point, tracking a vehicle through a characteristic point of labeling a target, recording position information of the tracking point, and calculating a vehicle position proportional variance on the basis of a tracking track characteristic so that whether a vehicle changes a lane is judged. Compared with the prior art, the method provided by the invention can be used for detecting all vehicle targets in a video range without being limited by the environment and judging real-time video, has the advantages of short detection time, easy implementation and higher accuracy, is very suitable for detecting the violation lane-changing incident of the vehicle in real time, and has wide application prospect.

Description

technical field [0001] The invention belongs to the technical field of video detection, and in particular relates to a video-based detection method for a vehicle illegal lane change event. Background technique [0002] In recent years, with the rapid development of the economy, the construction of road traffic has also developed rapidly, and the number of motor vehicles has also increased rapidly. Under the circumstance that the construction of traffic infrastructure and popularization of traffic regulations are relatively lagging behind, traffic problems are becoming more and more serious, traffic accidents occur frequently, urban traffic is congested, and the traffic environment continues to deteriorate. Statistics show that about 70%-80% of traffic accidents are caused by the driver's abnormal driving behavior on the vehicle, including driver's illegal driving, fatigue driving and so on. Therefore, in order to create a better traffic environment, the detection of these v...

AI Technical Summary

Problems solved by technology

Video-based vehicle lane change detection methods have become a research hotspot. Although these methods can realize the alarm of vehicle violation lane change events, the processing process of video data is complicated and the reliability is poor, which cannot meet the real-time requirements of detection and the requirements of practical applications.
