Abstract

For the skeleton extraction of complex point clouds, due to the occlusion, deficiency of original point cloud, uneven distribution, complex branching and other reasons, the extracted skeleton would have problems such as fracture and topology error. Aimed at the skeleton extraction of complex structure point clouds, this paper proposed a complex point cloud skeleton extraction algorithm MDSE based on level division. The algorithm used L1-medial to extract the initial skeleton points and connected the initial skeleton points into a single branch, divided the set of single branches into different levels and used average bifurcation angle of the connected branches to repair the broken skeleton from the bottom level to top level. Finally, it adopted the Cardinal spline to improve the skeleton shape, forming a complete skeleton that conformed to the original point cloud's topology. Experimental results show that the algorithm can extract a relatively complete skeleton line with correct topological structure from a complex point cloud.
