Neural surfaces learning has ... impressive performance in multi-view surface reconstruction. However, most ... use large multilayer perceptrons (MLPs) resulting in hours of training
... propose a prior-based residual learning paradigm for ... reconstruction. This paradigm consists of two optimization stages.
... first ... propose to leverage generalization models to generate a basis signed distance function (SDF) field. This ... can ... be ... obtained by fusing multiple local SDF fields produced by generalization models. This provides a coarse global geometry prior.
... second ... a fast residual learning strategy based on hash-encoding networks is proposed to encode an offset SDF field for the basis SDF field.
... introduce a prior-guided sampling scheme to help the residual learning stage converge better, and thus recover finer structures.
... takes about 3 minutes to reconstruct the surface of a single scene, while achieving competitive surface quality ...
