description The invention relates to the technical field of point cloud data processing, in particular to a vehicle-mounted laser point cloud data repeatability precision evaluation method and device, and the method comprises the steps: obtaining vehicle-mounted track data and vehicle-mounted laser point cloud data; dividing the vehicle-mounted laser point cloud data into a plurality of segmented point clouds according to the vehicle-mounted track data, obtaining point cloud query features according to the segmented point clouds, and obtaining repeatability precision evaluation according to the point cloud query features. Therefore, from the perspective of repeatability precision evaluation, repeatability precision evaluation is carried out on an area with repeated point clouds, and control points do not need to be specially and manually arranged for any collected point cloud data. According to the method, manual control point layout work is avoided, so that the technical problems of high working intensity, long time con
