A roof-contour guided multi-side interpolation method for building texture-mapping using remote sensing resource

In this paper, we proposed a novel texture-mapping method for buildings using remote sensing images and digital surface model. For generating better 3D map, boring manually or semi-automatic texture-mapping of buildings is always needed. However, only with remote sensing images and digital surface model, it is difficult to generate `sides´ of buildings, and corresponding relation between triangular mesh and texture image is also hard to be found. Inspired by building extraction result, we found that roof-contour could guide interpolation of `sides´ of building, and generate triangular mesh, and an interactive frame of texture mapping is introduced for processing the generated multi-sides and corresponding texture-images of buildings. Experiments show that texture-mapping of buildings using remote sensing resource is easily realized with our frame, and excellent results could be obtained.
