Research on Three-Dimensional Point Clouds Processing for Standing Tree Volume Based on Laser Scanner

In this paper, a measurement approach for standing tree volume based on laser scanner is presented, which uses geometry analysis to process three-Dimensional point cloud data and makes a program with VC++ and Matlab. As shown by the test, the standing tree volume can be worked out fast and exactly and the error of which is less than 3 percent. If more trees are scanned simultaneously, the forest inventory will be measured automatically and substantive manpower and material resources will be saved.
