Voxurf: Voxel-based Efficient and Accurate Neural Surface Reconstruction. (arXiv:2208.12697v1 [cs.CV])

Neural surface reconstruction aims to reconstruct accurate 3D surfaces based
on multi-view images. Previous methods based on neural volume rendering mostly
train a fully implicit model, and they require hours of training for a single
scene. Recent efforts explore the explicit volumetric representation, which
substantially accelerates the optimization process by memorizing significant
information in learnable voxel grids. However, these voxel-based methods often
struggle in reconstructing fine-grained geometry. Through empirical studies, we
found that high-quality surface reconstruction hinges on two key …
