摘要/Abstract

摘要： 骨架点是单株树木几何模型重建的基础。本文结合水平集、聚类方法和图论3种方法，采用ILMSVP和天宝SX10获取模拟与实测单株树木点云数据，并实现单株树木骨架点提取，其中模拟数据用于方法实现，实测数据用于验证。为解决单株树木点云数据缺失情况，本文重复利用水平集、聚类方法和图论方法得到较完整的单株树木骨架点。结果表明：本文采用的单株树木骨架点提取方法可行。

Abstract: Skeleton point is the basis of geometric model reconstruction of single tree. This paper combines three methods of level set, clustering and graph theory to extract skeleton points of single tree by using LIMSVP and Trimble SX10 to obtain point cloud data of simulated and measured single tree, and realize the skeleton point extraction of single tree. The simulation data is used for method implementation and the measured data is used for verification. In order to solve the problem of missing point cloud of single tree, three methods of level set, clustering and graph theory are reused to obtain more complete skeleton point of single tree. The results show that the method of extracting skeleton points of single tree is feasible.

Key words: point cloud, skeleton, neighborhood map, mapping, ILMSVP, Trimble SX10
