Abstract: In order to overcome the problem of low recognition rate of building image when constructing three-dimensional model with traditional methods, a new idea of top shape and structure model of assembly building based on BIM is proposed in this paper. The method calculates and identifies the structural parameters of the top contour of assembly building according to BIM technology, retrieves the internal model of the top contour structure of assembly building from the database which is consistent with the result of feature recognition, and obtains the three-dimensional construction of image surface and the three-dimensional modelling of scattered point cloud surface through digital camera and point cloud data, so as to build the final three-dimensional model. Finally, the three-dimensional visualisation of assembly is realised. The experimental results show that the proposed method has high recognition rate.
