High-Quality 3D Reconstruction by Joint Appearance and Geometry Optimization with Spatially-Varying LightingMS57

We present a novel method to obtain high-quality 3D reconstructions from consumer RGB-D sensors. Our core idea is to simultaneously optimize for geometry encoded in a signed distance field, textures from automatically-selected keyframes, and their camera poses along with material and scene lighting. To this end, we propose a joint surface reconstruction approach that utilizes Shape-from-Shading techniques and spatially-varying spherical harmonics. We demonstrate that our method dramatically improves both reconstructed scene geometry and surface texture.
