AUTOMATIC BUILDING ABSTRACTION FROM AERIAL PHOTOGRAMMETRY

AUTOMATIC BUILDING ABSTRACTION FROM AERIAL PHOTOGRAMMETRY

Multi-view stereo has been shown to be a viable tool for the creation of realistic 3D city models. Nevertheless, it still states significant challenges since it results in dense, but noisy and incomplete point clouds when applied to aerial images. 3D city modelling usually requires a different rep...
