[Paper] [Video]

Windows or Linux, Python3.7

conda install pytorch torchvision torchaudio cudatoolkit=11.3 -c pytorch
pip install -r requirements.txt

Step1:
Download the official SMPL model from SMPLify website and put it in models/smpl. (see models/smpl/readme.txt)

Step2:
Download the test data and trained motion prior from Google Drive or Baidu Netdisk (extraction code [jomn]) and put them in data.

Step3:
Run

python main.py --config cfg_files/fit_smpl.yaml

You can visualize the motions and cameras in optimization with the command:

python main.py --config cfg_files/fit_smpl.yaml --visualize true

The code can also be used for motion capture with known cameras:

python main.py --config cfg_files/fit_smpl.yaml --opt_cam false

The fitted results will be saved in output.
You can visualize the estimated extrinsic camera parameters by running:

python viz_cameras.py
