The invention provides a point cloud processing method and device, and relates to the field of point cloud data processing. The method comprises the steps of obtaining point cloud collected by a ground mobile measurement system, dividing the point cloud into a plurality of horizontal grids according to a track line of the ground mobile measurement system, and obtaining the point cloud corresponding to each horizontal grid; performing clustering analysis on the point cloud of each horizontal grid to obtain point clouds corresponding to the clustering objects, and screening out the point cloudsconforming to the rod characteristics of the rod-shaped objects from the point clouds corresponding to the clustering objects; and extracting point clouds meeting preset parameter requirements from the point clouds meeting the rod characteristics of the rod-shaped object. The method can achieve the automatic analysis of the point cloud, recognizes the point cloud corresponding to the rod-shaped object in the point cloud, and has higher extraction efficiency of the point cloud of the rod-shaped object.
Description
technical field [0001] The present application relates to the field of point cloud data processing, in particular, to a point cloud processing method and device. Background technique [0002] Three-dimensional laser measurement technology refers to: obtain the point cloud of the surface of the object by scanning the object, and then extract the feature of the point cloud through the data production software in the industry, so as to realize the modeling of the object or the classification and recognition of related objects in the environment. [0003] At present, in the process of feature extraction of the obtained point cloud, when extracting the features of pole-shaped objects, such as road trees, power poles, street light poles, communication poles, etc., it is usually judged by manual recognition whether the shape of the point cloud conforms to the Rods, so as to perform feature extraction on point clouds conforming to the shape of rods. [0004] However, in the above e...
