Polygom2K2K Dataset

High-fidelity 3D Human Digitization from Single 2K Resolution Images

[Project Page]

This repository provides new 2K2K dataset updated by Polygom.
Specifically, we provides same 1M mesehs of original 2K2K dataset with newly updated SMPLX parameters and registered SMPLX via non-rigid fitting.
Both SMPLX rigid and non-rigid fittings are simply optimized by noisy 3D keypoint and chamfer distance to the nearest point. Therefore noticable misalignment can be observed in some region (e.g. hair, hand, and foot). If you need accurately aligned SMPLX, please postprocess it.

Data explanation

Polygom2K2K includes 2,050(train 2000, test 50) high-fidility 3D body scans captured by 80 multi-view DSLR cameras by IOYS. Each scan is simplified to a maximum of 1M vertices. Scans with fewer than 1M vertices are provided in their raw form. The data is provided in PLY format, including vertex colors.

Additionally, we provide the results of SMPLX rigid fitting and non-rigid registration.

Raw meshes are normalized in [0, 1] x [0, 1] x [0, 1] unit cube and centerd at (x0.5, y0.0, z0.5). (ground plane is xz plane and up-direction is +y.)
SMPLX parameters from rigid fitting consist of "poses", "shapes", "expression", "Rh" (global orientation), and "Th" (global translation). Reconstruct it into mesh using the SMPLX layer then multiply "scale".
SMPLX final meshes from non-rigid fitting are optimized by pytorch-nicp
