| Abstract: | Spatial 3D point cloud can be quickly captured on object surface by laser scanning; however its data volume is huge. Through the analysis of features of 3D laser scanning data, this paper advances two methods of data compression, barycenter of area data compression method and common vertex data compression method based on 3D triangulated irregular network. It introduces the principle and the process of the two data compression methods, and the compression results are obtained. |
