Problems solved by technology
In the current technical solution, ground points are identified by calculating the height difference of points within a predetermined area, and there may be cases where points belonging to small target objects are misidentified as ground points, which makes the accuracy of ground point recognition results low. This will lead to the occurrence of mistaken deletion or omission of ground points

Embodiments of the present application provide a method and device for identifying ground points in a point cloud. The identification method of the point cloud ground point includes: according to the height of the point to be detected in the point cloud data set, obtaining a sample point set from the point cloud data set; based on the sample point set, establishing a plane model about the sample point set ; Identify the points to be detected in the point cloud data set other than the sample point set and conform to the plane model as ground points. The technical solution of the embodiment of the present application recognizes ground points by means of a plane model, which can effectively avoid identifying points to be detected belonging to small target objects as ground points, so as to improve the accuracy of ground point recognition results.
Description
technical field [0001] The present application relates to the field of computer technology, and in particular, to a method and device for identifying point cloud ground points. Background technique [0002] The ground points contained in the point cloud data will cause certain interference to the results of target detection. Therefore, the ground points contained in the point cloud data should be identified and deleted before target detection. In the current technical solution, by calculating the height difference of points within a predetermined area to identify ground points, there may be situations such as misidentifying points belonging to small target objects as ground points, etc., resulting in low accuracy of ground point identification results. This will lead to the accidental deletion or omission of ground points. SUMMARY OF THE INVENTION [0003] The embodiments of the present application provide a method and device for identifying ground points in a point cloud...
