Abstract:

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%. If more trees are scanned simultaneously, the forest inventory will be measured automatically and substantive manpower and material resources will be saved.

Key words: laser scanner, standing tree volume, forest inventory, three dimensional point cloud data
