Study on building modeling based on 3-D laser scanning technology

In order to study the best 3-D modeling method of the building point cloud data, the point cloud data of a building were acquired with a 3-D laser scanner and pretreated. Three methods were used for the modeling of the buildings. From the view of modeling effect and complexity, the model effect with the SketchUp software was the best. The results show that the modeling effect of the point cloud data of buildings with SketchUp software is better than those with the scanner system software CYCLONE and AutoCAD software.
