The embodiment of the invention relates to the field of inspection vehicles, and discloses a parking lot license plate acquisition method, an inspection vehicle and a storage medium. The method comprises the steps that image acquisition is carried out on a parking space where a vehicle is parked in a parking lot, and a parking space image is obtained and comprises a license plate number image; calculating first coordinate information of the license plate number image in the parking space image; acquiring second coordinate information of the inspection vehicle in a geographic coordinate system and third coordinate information of a current parking space corresponding to the parking space image in the geographic coordinate system; converting the first coordinate information into the geographic coordinate system by using the second coordinate information to obtain fourth coordinate information; and associating the third coordinate information, the fourth coordinate information and the license plate number corresponding to the license plate number image to obtain the license plate number with the third coordinate information. A geomagnetic sensor does not need to be additionally arranged on each parking space of the parking lot, the inspection vehicle can be used after being modified, and the inspection efficiency is high.
本申请实施例涉及巡检车领域,公开了一种停车场车牌获取方法、巡检车及存储介质。所述方法包括:对停车场上停有车辆的停车位进行图像采集,获得停车位图像,且停车位图像包括车牌号图像;计算所述车牌号图像在所述停车位图像中的第一坐标信息;获取所述巡检车在地理坐标系下的第二坐标信息和所述停车位图像对应的当前停车位在地理坐标系下的第三坐标信息;利用所述第二坐标信息,将所述第一坐标信息转换到所述地理坐标系下,获得第四坐标信息;将所述第三坐标信息、第四坐标信息及所述车牌号图像对应的车牌号关联,获得具备所述第三坐标信息的车牌号码。本申请无需在停车场的每个停车位上单独加装地磁传感器,改装巡检车即可投入使用,且巡检效率高。
