Unofficial PyTorch reimplementation of Hand-Biomechanical-Constraints

Hand Biomechanical Constraints Pytorch

Unofficial PyTorch reimplementation of Hand-Biomechanical-Constraints (ECCV2020).

This project reimplement following components :

  1. 3 kinds of biomechanical soft constraints
  2. integrate BMC into training procedure (PyTorch version)

Usage

Download data

Download 3D joint location data joints.zip Google Drive or Baidu Pan (2pip), and . These statistics are from following datasets:

Note the data from these datasets under their own licenses.

Calculate BMC

BMC

Run the code

python calculate_bmc.py

You will get

  • bone_len_max.npy bone_len_min.npy for bone length limits
  • curvatures_max.npy curvatures_min.npy for Root bones’ curvatures
  • PHI_max.npy PHI_min.npy for Root bones’ angular distance
  • joint_angles.npy for Joint angles

And if u want to check the coordinate system, run the code

cd utils
python calculate_joint_angles.py
