MMHuman3D is an open-source PyTorch-based codebase for the use of 3D human parametric models in computer vision and computer graphics. It is a part of the OpenMMLab project.

The main branch works with PyTorch 1.7+.

If you are interested in multi-view motion capture, please refer to XRMoCap for more details.


Major Features

  • Reproducing popular methods with a modular framework

    MMHuman3D reimplements popular methods, allowing users to reproduce SOTAs with one line of code. The modular framework is convenient for rapid prototyping: the users may attempt various hyperparameter settings and even network architectures, without actually modifying the code.

  • Supporting various datasets with a unified data convention

    With the help of a convention toolbox, a unified data format HumanData is used to align all supported datasets. Preprocessed data files are also available.

  • Versatile visualization toolbox

    A suite of differentiale visualization tools for human parametric model rendering (including part segmentation, depth map and point clouds) and conventional 2D/3D keypoints are available.
