The invention provides a license plate recognition method, device and equipment and a storage medium. The method comprises the steps of obtaining a target image collected by a computer vision sensor;detecting a vehicle in the target image by adopting a preset vehicle detection model to obtain at least one vehicle detection result image, wherein the vehicle detection model comprises a positive sample classifier trained to converge, a negative sample classifier trained to converge and a detection result analysis sub-model; detecting and correcting a license plate in the vehicle detection resultimage by adopting a preset deformation plane target detection model to obtain a license plate detection and correction result image; and recognizing license plate characters in the license plate detection correction result image. Since the vehicle detection result image is firstly identified and the correction operation is performed on the vehicle detection result image, the identification of thelicense plate information can be realized when the license plate image has the inclined visual angle.
本公开提供了一种车牌识别方法、装置、设备及存储介质,方法包括:获取计算机视觉传感器采集的目标图像;采用预设的车辆检测模型对所述目标图像中的车辆进行检测,以获得至少一幅车辆检测结果图像;所述车辆检测模型中包括训练至收敛的正样本分类器、训练至收敛的负样本分类器及检测结果解析子模型;采用预设的变形平面目标检测模型对所述车辆检测结果图像中的车牌进行检测和校正,以获得车牌检测校正结果图像;对所述车牌检测校正结果图像中的车牌字符进行识别。由于首先识别车辆检测结果图像,并对车辆检测结果图像进行校正操作,从而能够在车牌图像存在倾斜视角时,也能够实现对车牌信息的识别。
