We introduce 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 (SDF), 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 is based on Shape-from-Shading (SfS) techniques and utilizes the estimation of spatially-varying spherical harmonics (SVSH) from subvolumes of the reconstructed scene. Through extensive examples and evaluations, we demonstrate that our method dramatically increases the level of detail in the reconstructed scene geometry and contributes highly to consistent surface texture recovery.

The following dataset contains RGB-D sequences and reconstructed 3D models of five different scenes. We captured the RGB-D data using a Structure.io depth sensor (640x480px) and an iPad color camera (1296x968px). Please refer to the respective publication when using this data.

For each scene of the Intrinsic3D dataset, we provide the respective RGB-D sequence as well as the fused and refined 3D models (PLY binary format). Each RGB-D sequence contains:

• Color frames (frame-XXXXXX.color.png): RGB, 24-bit, PNG
• Depth frames (frame-XXXXXX.depth.png): depth (mm), 16-bit, PNG (invalid depth is set to 0)
• Camera poses (frame-XXXXXX.pose.txt): camera-to-world pose computed by VoxelHashing
• Camera calibration (colorIntrinsics.txt and depthIntrinsics.txt): color and depth camera intrinsics (default factory calibration).

For reference, the RGB-D data is provided in the same format as specified here. The Intrinsic3D source code on github can directly read and process sequences in this format.
