Bihoi data samples

This release is a 100-sequence subset of the full BIHOI dataset, covering bimanual hand–object interactions across 18 object categories. 88,570 frames at 30 fps, interpolated from 10 fps pose estimates.

Download

hf download YFEI002/Bihoi-data-samples --repo-type dataset --local-dir ./bihoi
cd bihoi
sha256sum -c SHA256SUMS
unzip BIHOI_100_standard_hoi_exports.zip

Format

Each sequence is stored in fwd_capture/<dataset>/<take>/standardized_hoi_30fps/.

File	Contents
`mano_left.npz`, `mano_right.npz`	MANO `global_orient` (T×3), `hand_pose` (T×45), `transl` (T×3), `betas` (10).
`obj_pose.npz`	Object `trans` (T×3), `quat` (T×4, wxyz).
`object_mesh.ply`	Canonical object mesh.
`frames.npy`, `source_frame_ids.npy`, `timestamps_sec.npy`	Frame indices, source-frame mapping and timestamps.
`metadata.json`, `table.json`, `README.md`	Sequence metadata, estimated table plane and format notes.

Units: meters and radians. Coordinates: right-handed, +Z up, tabletop at Z=0. MANO poses use axis-angle with flat_hand_mean=True. Object poses transform the supplied mesh into world coordinates.

sequences.csv lists all sequences and frame counts; SHA256SUMS provides file checksums. MANO model weights and RGB videos are not included.
