Texture Mapping in 3D City Building

Texture is an important factor influencing the realistic 3D model. The final purpose of 3D texture mapping is that the 3D model has high precision, automatic, high fidelity, and it is a hot issue in the field of computer vision. This paper introduces the principle and process of 3D texture mapping. For this research direction about texture mapping for 3D building model, the existing solutions are summarized on the projection of parametric applications, texture coordinate transformation processing, image and model matching. Some research methods and results of representative were compared and analyzed on texture mapping for multiple building facades and roofs of remote sensing image vertical tilt imaging and three -dimensional geometry model; finally, the author puts forward some problems and possible solutions based on the present research situation and current application needs.
