True Orthoimage Generation Based on Occlusion Detection with TIN

  • To the problems about building tilt and ghost image on traditional orthoimage,a novel method for true orthoimage generation based on occlusion detection with TIN(TOGODT) is proposed.The triangle is the dectection unit in this method.Occlusions are dectected by visual sorting of triangles,and occlusion areas are repaired by visible parts of the neighbor images which are treated as weighted image.The experimental results show that this method can accurately detect image occlusion areas,and the generated true orthoimage is complete and has no occlusion.
