HandTailor

This repository is the implementation code and model of the paper "HandTailor: Towards High-Precision Monocular 3D Hand Recovery" (BMVC2021) (paper). You can find the video demo on the webpage.

Get the Code

git clone https://github.com/LyuJ1998/HandTailor.git
cd HandTailor

Install Requirements

Please install the dependencies listed in requirements.txt.

pip install -r requirements.txt

Download Model Files

Pretrain Model

Download the pretrain model from Google Drive, and put the model.pt in ./checkpoints

MANO Model

• Go to MANO website

• Download Models and Code (the downloaded file should have the format mano_v*_*.zip). Note that all code and data from this download falls under the MANO license.
• unzip and copy the MANO_RIGHT.pkl file into the folder

Demo

To process the image provided in ./demo, run

python demo.py

You can also put your data in the fold ./demo, but remember to use the proper camera intrinsic like

python demo.py --fx=612.0206 --fy=612.2821 --cx=321.2842 --cy=235.8609

If camera information is unavailable, run

python demo_in_the_wild.py

We recommand you to utilize the camera intrinsic, which will improve the performance a lot.

Realtime Demo

To reconstruct the hand from image captured with a webcam,run the following command. Also remember to use the proper camera intrinsic, the following command is for RealSense D435

python app.py --fx=612.0206 --fy=612.2821 --cx=321.2842 --cy=235.8609

When camera information is absence

python app_in_the_wild.py

When using HandTailor to recovery hand mesh, you need to make sure that the hand is in the dominate area of the image. To address this, we also implement a naive tracker.

Please run:

python app_with_tracker.py --fx=612.0206 --fy=612.2821 --cx=321.2842 --cy=235.8609

This is a quite simple tracker, so do not move your hand too fast. And once track lost, put your hand on the bounding box to fix it.
