3D Instance Segmentation of MVS Buildings. (arXiv:2112.09902v2 [cs.CV] UPDATED)

We present a novel 3D instance segmentation framework for Multi-View Stereo
(MVS) buildings in urban scenes. Unlike existing works focusing on semantic
segmentation of urban scenes, the emphasis of this work lies in detecting and
segmenting 3D building instances even if they are attached and embedded in a
large and imprecise 3D surface model. Multi-view RGB images are first enhanced
to RGBH images by adding a heightmap and are segmented to obtain all roof
instances using a fine-tuned 2D instance …
