Research on the method of constructing tree branch skeleton based on point cloud data

In this paper, we propose a new method for constructing tree branch skeleton lines, using 3D laser scanning technology to measure several single tree point clouds, using them as data sources for accurate alignment, and performing initial denoising on the aligned overall tree point clouds. The point cloud data is secondly denoised, and the point cloud data with multiple tree branches in the same layer are identified by clustering, and the feature points of each segment are sorted and extracted to extract the skeleton points, and finally the tree branch skeleton line is constructed by building a minimum spanning tree.
