RangeUDF: Semantic Surface Reconstruction from 3D Point Clouds. (arXiv:2204.09138v1 [cs.CV] CROSS LISTED)

We present RangeUDF, a new implicit representation based framework to recover
the geometry and semantics of continuous 3D scene surfaces from point clouds.
Unlike occupancy fields or signed distance fields which can only model closed
3D surfaces, our approach is not restricted to any type of topology. Being
different from the existing unsigned distance fields, our framework does not
suffer from any surface ambiguity. In addition, our RangeUDF can jointly
estimate precise semantics for continuous surfaces. The key to our …
