The embodiment of the invention relates to the field of inspection vehicles, and discloses a license plate and parking space detection method and device, an inspection vehicle and a storage medium. The method comprises steps that image acquisition and laser point cloud acquisition are carried out on a parking space where a vehicle is parked in a parking lot, a parking space image and a parking space point cloud are acquired, and the parking space image comprises a license plate number image; projecting the license plate number image to the parking space point cloud to obtain first coordinate information of the license plate number image in a parking space point cloud coordinate system; converting the first coordinate information into a geographic coordinate system to obtain second coordinate information; and if the license plate number corresponding to the license plate number image and the second coordinate information are both located in the parking space coordinates corresponding to the parking space point cloud, associating the license plate number corresponding to the license plate number image and the second coordinate information with the parking space coordinates to obtain the license plate number with the parking space coordinates. The parking lot does not need to be transformed, the transformed inspection vehicle can be put into use, the inspection efficiency is high, and the license plate number recognition precision is high.

    本申请实施例涉及巡检车领域,公开了一种车牌与车位检测方法、装置、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及激光点云采集,获得停车位图像及停车位点云,且停车位图像包括车牌号图像;将车牌号图像投影到停车位点云上,获得车牌号图像在停车位点云坐标系下的第一坐标信息;将第一坐标信息转换到地理坐标系,获得第二坐标信息;如果车牌号图像对应的车牌号、第二坐标信息均位于停车位点云对应的停车位坐标内,则将车牌号图像对应的车牌号、第二坐标信息均和停车位坐标关联,获得具备停车位坐标的车牌号。本申请无需对停车场改造,改装巡检车即可投入使用,巡检效率高,且车牌号识别精度高。
