3d Mesh Reconstruction From Height Map And Post Processing

Nowadays, researches for reconstructing 3D terrain from images are being widely carried out. The method of reconstruction according to the kind of the input image and the post-processing process after reconstruction are different. In this paper, we propose a 3D mesh generation and post-processing method based on a height map generated from a satellite image. First, we generate 3D mesh based on height map, then execute refinement of 3D mesh to remove stair shape on the side of building, and finally simplify them.
