Application analysis of laser scanning technology in trees measurement

This paper introduced the procedure of forest measurement using three-dimensional laser scanning and summarized the method of data processing by the experiment in Xiaolong Mountain of Gansu Province. The way of establishing 3D visualization model of trees using 3D laser scanning data was brought forward as well. And model accuracy was verified. The results show that the model reconstructed using this method can not only be measured with high accuracy of the tree measurement factors such as height and DBH to meet the requirements of forestry survey, but also provide multitudinous 3D models of single tree for the 3D visualization simulation of stand and landscape.
