Abstract

Three-dimensional laser scanning can be used to collect the 3D coordinate information on the object surface to create 3D point clouds, which can reflect the characteristics of the target surface, facilitating the establishment of terrain model. Since point clouds lacunarity is usually caused by occlusion of ground features during the vehicle-borne laser scanning, the existing modeling algorithms are not fully suitable for vehicle-borne laser point clouds. In this paper, a modeling algorithm was designed to be different from the previous ones, in which the model was built by constructing Delaunay triangulation. Instead, a bounding box algorithm was adopted for the modeling of vehicle-borne laser point clouds, which were structured in an octree. This could not only fill the point cloud holes found in modeling, but also improve the storage efficiency of the point clouds.
