3D object reconstruction from 2-3 images using geometry reasoning with SparseNeuS


SparseNeuS: Fast Generalizable Neural Surface Reconstruction from Sparse views

arXiv paper abstract https://arxiv.org/abs/2206.05737



... introduce SparseNeuS, a novel neural rendering based method for the task of surface reconstruction from multi-view images.


... task ... more difficult when only sparse images ... as input ... Moreover ... inability of generalizing to unseen new scenes


... Contrarily, SparseNeuS can generalize to new scenes and work well with sparse images (as few as 2 or 3).


SparseNeuS adopts signed distance function (SDF) as the surface representation, and learns generalizable priors from image features by introducing geometry encoding volumes for generic surface prediction.


... strategies ... for ... reconstruction, including 1) ... recover the surfaces in a coarse-to-fine manner; 2) a multi-scale color blending scheme ... 3) ... control the inconsistent regions caused by occlusion and noise.


... approach ... outperforms the state-of-the-art methods, but also exhibits good efficiency, generalizability, and flexibility.
