ICL-Gait: A Real-World Multi-View Pathological Gait Dataset

Dataset | Supplementary Code



Introduction

This is a dataset collected for Cross-Subject, Cross-View, Sim2Real, Cross-Modality gait pose estimation and abnormal gait pattern recognition.

We provide data of multiple modalities, including Depth, Point Cloud, Kinematics, Segmentation Map and 2D Keypoints. Access to raw RGB data was temporally suspended for ethics issue.


Description

Real-World Dataset

  • 5 Gait Conditions + 5 Viewpoints + 8 Subjects

  • RGB and Depth images were collected by RealSense D435.
  • 3D skeleton and kinematics collected by Vicon and CGM2.
  • Segmentation Map generated by CDCL.
  • 2D Keypoints generated by OpenPose.



    • Synthetic Data

  • Synthetic data generated by SMPL.
  • Joints parameteres from real-world dataset.
  • Varied shapes, viewpoints, occlusions.
  • Occlusion rendered by Open3D.
