Topological Features Detection and Automatic Segmentation of Point Clouds from Tree Surface

In this paper, the tree topological features detection and automatic segmentation of point cloud data are studied, and propose a method of topological features detection and automatic segmentation of point cloud data, based on panoramic range image.First of all, the point cloud data is converted into the cylindrical polar coordinates and create the panoramic range image of trees.Then, according to the level of the different structural characteristics can be automatic segmentation trees.These feature points trees point cloud can be divided into two parts of the tree trunks and branches structure.The experimental results show that the method can improve the efficiency and accuracy of the topological features detection and automatic segmentation of the point clouds.
