摘要：In this paper, we propose a new approach to extract planar patches and boundary from a set of LiDAR point cloud. In the beginning, the 3D point cloud set is partitioned and assigned to fixed-size cubes. Secondly, local planar patches are generated by extracting surface normal vectors within each cube. Finally, the global planes are formed by grouping the planar patches. The boundary of global plans is retrieved by projecting point cloud onto 2D convex hulls
