3D Optical Flow DROID Dataset

Processed DROID robotics dataset with optical flow and scene flow annotations.

Dataset Structure

Organized by lab, each trajectory in separate tar.gz archive:

IPRL/IPRL+2023-06-19+Mon_Jun_19_23:27:48_2023.tar.gz
CLVR/CLVR+2023-...tar.gz
... (15 labs, ~33K trajectories)

Each trajectory contains:

• metadata.json - Trajectory metadata
• trajectory.h5 - Robot state and actions
• camera_left/, camera_right/ - Camera data
  • rgb/ - RGB images
  • depth/ - Depth maps
  • optical_flow_with_mask/ - 2D optical flow
  • scene_flow/ - 3D scene flow

Usage

from huggingface_hub import hf_hub_download
import tarfile

# Download specific trajectory
tar_path = hf_hub_download(
    repo_id="Salesforce/3d_optical_flow_droid",
    filename="IPRL/IPRL+2023-06-19+Mon_Jun_19_23:27:48_2023.tar.gz",
    repo_type="dataset"
)

# Extract
with tarfile.open(tar_path, "r:gz") as tar:
    tar.extractall("./data")
