The embodiment of the invention discloses a vehicle illegal parking behavior detection method and device and a medium. The method comprises the following steps: acquiring a long-range image of an illegal parking area by using a dome camera; analyzing the distant view image based on a deep learning vehicle detection algorithm to extract vehicle feature information of each vehicle in the illegal parking area; and controlling the dome camera to acquire close-range images of the vehicles in the illegal parking area in a zooming manner. If a target vehicle whose stay time exceeds a preset time limit value exists in the illegal parking area, a license plate recognition algorithm is used to recognize a close-shot image of the target vehicle, and if a recognition result does not meet a license plate recognition requirement, when it is detected that the target vehicle moves out of the illegal parking area, the dome camera is controlled to collect a close-range image of the target vehicle leaving the illegal parking area in a zooming manner; and the close-range image of the target vehicle leaving the illegal parking area is recognized by using a license plate recognition algorithm to obtain the license plate number of the target vehicle. By collecting the close-range image of the target vehicle leaving the illegal parking area, the snapshot problem of the illegal parking vehicle with the shielded license plate is effectively solved.

    本申请实施例公开了一种车辆违停行为的检测方法、装置和介质,利用球机采集违停区域的远景图像;基于深度学习的车辆检测算法对远景图像进行分析,以提取违停区域内各车辆的车辆特征信息;控制球机变倍采集违停区域内各车辆的近景图像。若违停区域内存在停留时间超过预设时间限值的目标车辆,则利用车牌识别算法对目标车辆的近景图像进行识别,若识别结果不满足车牌识别要求,则在检测到目标车辆移出违停区域时,控制球机变倍采集目标车辆驶离违停区域的近景图像;利用车牌识别算法对目标车辆驶离违停区域的近景图像进行识别,以得到目标车辆的车牌号码。通过采集目标车辆驶离违停区域的近景图像,有效解决了车牌被遮挡的违停车辆抓拍问题。
