ABSTRACT
The 3D photo-realistic building model does not only present the building in the three-dimensional perspective but also reveals its real appearance. There have been a number of approaches for reconstructing the geometric model from photogrammetric images, from LiDAR point cloud, or from both of them. However, the façade texture generation and mapping require massive labor works, therefore, are still the bottle neck in the photo-realistic building modeling process. A semi-automated approach to modeling 3D photo-realistic buildings using smartphones or tablet PCs is proposed in this paper. The built-in GPS
