AMASS: Archive of Motion Capture as Surface Shapes

alt text

AMASS is a large database of human motion unifying different optical marker-based motion capture datasets by representing them within a common framework and parameterization. AMASS is readily useful for animation, visualization, and generating training data for deep learning.

Here we provide tools and tutorials to use AMASS in your research projects. More specifically: - Following the recommended splits of data by AMASS, we provide three non-overlapping train/validation/test splits. - AMASS uses an extended version of SMPL+H with DMPLs. Here we show how to load different components and visualize a body model with AMASS data. - AMASS is also compatible with SMPL and SMPL-X body models. We show how to use the body data from AMASS to animate these models.

Requirements - Python 3.7 - PyTorch 1.7.1 - Human Body Prior - Pyrender for visualizations

Clone this repo and run the following from the root folder:

python install -r requirements.txt
python develop

Body Models

AMASS uses MoSh++ pipeline to fit SMPL+H body model to human optical marker based motion capture (mocap) data. In the paper we use SMPL+H with extended shape space, i.e. 16 betas, and 8 DMPLs. Please download models and place them them in body_models folder of this repository after you obtained the code from GitHub.


We release tools and Jupyter notebooks to demonstrate how to use AMASS to animate SMPL+H body model.

Furthermore, as promised in the supplementary material of the paper, we release code to produce synthetic mocap using DFaust registrations.

Please refer to tutorials for further details.

Contribute to AMASS

The research community needs more human motion data. If you have interesting marker based motion capture data, and you are willing to share it for research purposes, then we will label and clean your mocap and MoSh it for you and add it to the AMASS dataset, naturally citing you as the original owner of the marker data. For this purposes feel free to contact [email protected].
