Embodiment Construction
[0080] The present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that the described embodiments are only intended to facilitate the understanding of the present invention, rather than limiting it in any way.
[0081] 1 Summary of beneficial effects of the method of the present invention (overview of approach)
[0082] The technical problem solved by the invention is to obtain a high-precision center line to represent the shape, and to eliminate the influence of the sub-branch on the main branch skeleton at the bifurcation. The method of the present invention is to extract the bifurcation center point through the classification skeleton, decompose the three-dimensional to eliminate the influence of sub-branches with the help of the bifurcation center point, use the compact centrality cost of accurate expression to create the minimum expansion tree, and use the minimum expansion tree The skeleton of the shape is ext...
