　　Three-dimensional laser scanning could acquire objects surface data quickly and accurately.However,the post-processing of point cloud is not perfect and could be improved.Based on the study of 3D laser scanning technology,this paper describes the details of solutions to modelling irregular ancient buildings and Buddha statues in Jinshan Temple,which aiming at data acquisition,modelling and texture mapping,etc.In order to modelling irregular ancient buildings effectively,the structure of each building is extracted manually by point cloud and the textures are mapped by the software of 3ds Max.The methods clearly combine 3D laser scanning technology with traditional modelling methods,and greatly improves the efficiency and accuracy of the ancient buildings restored.On the other hand,the main idea of modelling statues is regarded as modelling objects in reverse engineering.The digital model of statues obtained is not just vivid,but also accurate in the field of surveying and mapping.On this basis,a 3D scene of Jinshan Temple is reconstructed,which proves the validity of the solutions.
