Abstract:Based on ROSA(Rotational Symmetry Axis)and mid-axis skeleton extraction algorithm,this paper builds a semi-automatic linear skeleton extraction experimental platform for point cloud model,systematically analyses the structure and characteristics of the experimental platform for point cloud model skeleton extraction based on skeleton-based interactive method,and expounds the skeleton node location extraction,skeleton connection extraction,skeleton editing and other functional modules in the experimental platform. Finally,the development of the experimental platform is summarized.
