Research on tree scanning and data processing based on 3D laser scanning system

In this paper, the non-contact FARO 3D laser scanning system was used for tree scanning, and the preprocessing of point cloud data as well as its accurate extraction was done in its affiliated software FARO SCENE. In addition, the software GEOMAGIC STUDIO was used to extract the tree measuring factors accurately. By comparison of the error analysis concerning scanning value and measuring value, the results have met the precision requirement of forest investigation factor, providing as the data support for certain area in measurement of 3D green biomass and its model establishment. It can also provide as guarantee for digitalization and informatization for forestry in the future.
