Embodiment Construction
[0072] The technical solutions of the present invention will be further specifically described below in conjunction with the accompanying drawings and embodiments.
[0073] The invention proposes a vehicle-mounted point cloud clustering method based on spatial context association. In this method, the density-based spatial clustering algorithm DBSCAN is used to segment point clouds to form supervoxels. By analyzing the characteristics of supervoxels and their spatial context correlations, multi-factor weights are used to cluster vehicle-mounted point clouds. In the clustering process, not only the spatial distance of points is considered, but also the spatial context association of neighboring points is combined, which greatly improves the problem of over-segmentation or under-segmentation of vehicle-mounted point cloud clustering.
[0074] The data in the embodiment is the city street point cloud data obtained by the Reigle vux-1 ground laser scanner, and the number of point c...
