Vehicle behavior detection method, device and system

Abstract

The invention relates to the technical field of computer vision, in particular to a vehicle behavior detection method, device and system. The vehicle behavior detection method comprises the steps of: acquiring a video stream sequence of a lane changing stage of a target vehicle; determining the target vehicle as a to-be-determined vehicle in response to the condition that the number of intersection points of a vehicle area of the target vehicle and a target solid line meets a preset condition; according to the vehicle area of the to-be-determined vehicle and lane areas of two lanes in the target real line segment, determining an overlapping area of the vehicle area and any one of the lane areas; and in response to the situation that the area of the overlapping region in the video stream sequence meets a first preset condition, determining the to-be-determined vehicle changes the lane while pressing a full line. According to the vehicle behavior detection method provided by the embodiment of the invention, the detection accuracy of vehicles changing lanes while pressing the full line is improved.

Description

Technical field [0001] The present disclosure relates to the field of computer visual technology, and more particularly to a vehicle behavior detection method, device, and system. Background technique [0002] At present, the vehicle is still an important participation object in the field of transportation, and the driving behavior of vehicles is also research hotspots in the transportation. In the actual life, some vehicles have acts that do not meet the driving specifications, such as the behavior of the vehicle in the traffic intersection and other scenes, which seriously affects or endangent the normal traffic order. [0003] In the relevant technologies, there is a problem with the low level of recognition efficiency and small coverage, and the vehicle behavior automation analysis recognition means is urgently needed to be based on field law enforcement or remote manual monitoring. Inventive content [0004] In order to achieve computer visual vehicle behavior analysis, the...

Problems solved by technology

In real life, some vehicles have behaviors that do not conform to the driving regulations, such as the behavior of vehicles changing lanes with compaction lines at traffic intersections, which seriously affects or endangers normal traffic order

[0003] In related technologies, methods such as on-site law enforcement or remote manual monitoring have the problems of low recognition efficiency and small coverage area, and there is an urgent need for automatic analysis and recognition of vehicle behavior based on computer vision
