With the rapid development of research fields such as smart city, intelligent navigation and automatic drive, the problem as to how to quickly achieve three dimensional space information of city buildings and build a high-precision 3D detailed model become a key problem. Based on the 2.5D features of airborne and vehicle-mounted LiDAR data, the authors established a technical scheme to generate 3D detailed model based on data integration with the using of 2.5D dual-contour method. The research shows that the method can express the details of the facade, such as the window and balcony, and has the advantages of simpleness, high efficiency and full automation.
