ABSTRACT
A 3D photo-realistic building model which can represent the real appearance of the building should be composed by precise geometric model and realistic façade images. There are a number of approaches to reconstructing the geometric model from photogrammetric images and LiDAR points cloud. However, the façade texture generation still relies on massive labor works, therefore, are still the bottle neck in the photo-realistic building modeling process. The emphasis of this paper will be put on the integration of sensors on a smartphone. While the camera is collecting the realistic photo of the building façade, the
