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.
本发明实施例提供一种车辆违法变道的检测方法和装置,该方法包括:获取多帧连续的待审核图像和待检测车辆的车牌信息;基于车辆检测网络模型识别待审核图像中的机动车辆及其位置信息;基于车牌检测网络模型获取机动车辆的车牌图像;基于图像文字识别模型在车牌图像中识别机动车辆的车牌信息;将待检测车辆的车牌信息与每个机动车辆的车牌信息进行匹配,将匹配成功的机动车辆确定为目标检测车辆;获取目标检测车辆所在图像中的路面标线信息;根据目标检测车辆在每一帧图像中的位置信息和路面标线信息,检测所述目标检测车辆是否违法变道。本实施例能够快速从复杂环境中识别目标车辆及其车牌信息并判断其是否违法变道,提高了检测准确率和效率。
