Clone repository

git clone https://github.com/robertjoosten/video2mocap.git

In order for this tool to work a couple of 3rd party application will have to be installed. To make this an easy process bat files are located in the 3rdparty directory and can be used to download/extract and install the necessary applications.

• Run 3rdparty/getFFmpeg.bat

  • Download and extract FFmpeg ( 20180630-9f0077c ).

• Run 3rdparty/getOpenPose.bat

  • Download and extract OpenPose ( 1.3.0 ).
  • Download models for OpenPose

• Run 3rdparty/getHMR.bat ( Requires python3 + pip3 accessible in PATH )

  • Pull the latest custom fork of the HMR repository.
  • Download models for HMR
  • Pip install requirements.txt

From the command line:

cd video2mocap/
python video2mocap.py --video_path <VIDEO> --output_dir <OUTPUT>

Available Arguments:

• --video_path: Path to video

• --output_dir: Directory to output the maya files too

• --keep_temp: Keep temp files for debugging ( False by default )

• --mayapy_exe: Overwrite mayapy.exe ( Default requires accessible in PATH )

• --python2_exe: Overwrite python.exe ( Default requires accessible in PATH )

• --python3_exe: Overwrite python3.exe ( Default requires accessible in PATH )

The exe files can be overwritten in case the python interpreters are not accessible through the PATH variable and a relative path cannot be provided.

• No camera tracking ( static camera advised )
• No partial body ( full body in view each frame advised )
• Limited depth adjustment

As loads of things are running in process it is quite simple for something to go wrong. For this reason a log file is implemented that gets saved into the output_dir. If the desired result is unexpected these logs can be investigated to find out what and where something went wrong.

Keypoint matching example:
