With the development of 3D laser scanning technology,this problem gradually resolved. Throughthe three-dimensional laser scanning technology can quickly build spatial 3D model with high precision, simulation of realistic 3D scenes. At present, the three-dimensional laser scanning technology has been widely applied in many fields, especially in the virtual scene,protect the cultural relics,deformation monitoring has a very broad prospects. This paper briefly introduced the composition of 3D laser scanning technology platform system and its working principle, application of terrestrial 3D laser scanning technology and the specific data processing. The three-dimensional point cloud data of Century Square of HPU as an example,the use of Cyclone, Cloudworx4.1 for Auto CAD,Auto CAD2007,3Ds MAX and other software to point cloud data splicing,denoising,segmentation,3D modeling, texture mapping and other operations,finally realizes the 3D reconstruction of scenes. And some problems which are analyzed,summarized and discussed. Key words: Three-dimensional laser
