The scanner has been widely used. With the development of science and technology, it is increasingly diversification. For instance, Contact 3D scanner, Non-contact 3D scanner, and Handhold Laser Scanner. In the Handhold Laser Scanner, it has high convenience and easy to carry. Because the operation isn’t complicated, the accuracy will not be reduced. This research through the simulation experiment, it can use the Handhold Laser Scanner go against earth and rocks change to do the scanning measurement. An application software programs-Rapidform XOR3 scan the point cloud data and establish the DEM to investigate the earth and rocks volume differences. Thence, we utilize the above method to come to a data and the actual rocky amount. Final, we do relative error analysis of the scan data and actual values precision.
Keywords: Handhold Laser Scanner, Rapidform XOR3, Earth and rocks change Measurement, Relative error.
