摘要：The task addressed in this paper is 3D modelling and reconstruction of (real world) trees on the basis of terrestrial laser scans. To identify the structure of a tree in terms of stem and branches, an algorithm has been designed in 3D voxel space, based on a selection of basic and advanced 2D raster (image) processing algorithms, transferred into the 3D domain. The selection includes filtering, mathematical morphology, skeletonization, connected component labeling and shortest route computation
