Vehicle illegal lane change detection method and device

Abstract

The embodiment of the invention provides a vehicle illegal lane change detection method and device. The method comprises the steps: acquiring multiple frames of continuous to-be-audited images and license plate information of a to-be-detected vehicle; identifying a motor vehicle and position information thereof in the to-be-audited image based on a vehicle detection network model; acquiring a license plate image of the motor vehicle based on the license plate detection network model; recognizing license plate information of the motor vehicle in the license plate image based on an image character recognition model; matching the license plate information of the to-be-detected vehicle with the license plate information of each motor vehicle, and determining the successfully matched motor vehicle as a target detection vehicle; acquiring road marking information in the image where the target detection vehicle is located; and detecting whether the target detection vehicle illegally changes lanes or not according to the position information and the road marking information of the target detection vehicle in each frame of image. According to the embodiment, the target vehicle and the license plate information thereof can be quickly identified from a complex environment and whether the vehicle illegally changes lanes or not is determined, so that the detection accuracy and efficiency are improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of intelligent transportation, in particular to a method and device for detecting illegal lane changes of vehicles. Background technique [0002] Illegal lane changing of vehicles is a very common traffic violation event. According to statistics, more than half of the traffic accidents are related to illegal lane changing. Illegal lane changing not only brings safety hazards to oneself, but also threatens the safety of other people. Therefore, the detection of illegal lane changes has important practical significance. [0003] In the prior art, the method of detecting illegal lane-changing vehicles is to install a camera on the road to capture the vehicles driving on the road, and relevant inspectors check whether the vehicles in the images are illegally changing lanes by checking the continuously captured multi-frame images. [0004] However, this method requires a lot of labor and ti...
