This paper presents a method of rapid automatic 3D building modeling and true texture mapping in urban area. The building model is extracted using polyhedral primitive based CSG model. With the building model, this paper addresses the true texture extraction method based on building model from aerial images. In order to accurately extracting texture information of building, accurate orientation parameters are needed. This approach also utilizes the geometric feature of building to match the model in order to get the accurate position. With this algorithm, the right texture of building roof and walls will be obtained. Based on the experimental result in Downtown, Denver, Colorado, it demonstrated that this method can effectively and rapidly reconstruct 3D buildings model with true texture in urban area.
