FrankMocap: A Strong and Easy-to-use Single View 3D Hand+Body Pose Estimator

FrankMocap pursues an easy-to-use single view 3D motion capture system developed by Facebook AI Research (FAIR). FrankMocap provides state-of-the-art 3D pose estimation outputs for body, hand, and body+hands in a single system. The core objective of FrankMocap is to democratize the 3D human pose estimation technology, enabling anyone (researchers, engineers, developers, artists, and others) can easily obtain 3D motion capture outputs from videos and images.

Btw, why the name FrankMocap? Our pipeline to integrate body and hand modules reminds us of Frankenstein's monster!

News:

• [2020/10/09] We have improved openGL rendering speed. It's about 40% faster. (e.g., body module: 6fps -> 11fps)

Key Features

• Body Motion Capture:

• Hand Motion Capture

• Egocentric Hand Motion Capture

• Whole body Motion Capture (body + hands)

Installation

• See INSTALL.md

A Quick Start

• Run body motion capture

  # using a machine with a monitor to show output on screen
  python -m demo.demo_bodymocap --input_path ./sample_data/han_short.mp4 --out_dir ./mocap_output
  
  # screenless mode (e.g., a remote server)
  xvfb-run -a python -m demo.demo_bodymocap --input_path ./sample_data/han_short.mp4 --out_dir ./mocap_output
  

• Run hand motion capture

  # using a machine with a monitor to show outputs on screen
  python -m demo.demo_handmocap --input_path ./sample_data/han_hand_short.mp4 --out_dir ./mocap_output
  
  # screenless mode  (e.g., a remote server)
  xvfb-run -a python -m demo.demo_handmocap --input_path ./sample_data/han_hand_short.mp4 --out_dir ./mocap_output
  

• Run whole body motion capture

  # using a machine with a monitor to show outputs on screen
  python -m demo.demo_frankmocap --input_path ./sample_data/han_short.mp4 --out_dir ./mocap_output
  
  # screenless mode  (e.g., a remote server)
  xvfb-run -a python -m demo.demo_frankmocap --input_path ./sample_data/han_short.mp4 --out_dir ./mocap_output
  

• Note:

  • Above commands use openGL by default. If it does not work, you may try alternative renderers (pytorch3d or openDR).
  • See the readme of each module for details
