Setup

Environment setup

Note that you will need a reasonably recent GPU to run this code.

We recommend using a conda environment:

conda env create -f environment.yml
conda activate phosa16

External Dependencies

Detectron2, NMR, FrankMocap

mkdir -p external
git clone --branch v0.2.1 https://github.com/facebookresearch/detectron2.git external/detectron2
pip install external/detectron2
mkdir -p external
git clone https://github.com/hassony2/multiperson.git external/multiperson
pip install external/multiperson/neural_renderer
cd external/multiperson/sdf
pip install external/multiperson/sdf
mkdir -p external
git clone https://github.com/hassony2/frankmocap.git external/frankmocap
sh scripts/install_frankmocap.sh

Install MANO

Follow the instructions below to install MANO
  • Go to MANO website: http://mano.is.tue.mpg.de/
  • Create an account by clicking *Sign Up* and provide your information
  • 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 (see http://mano.is.tue.mpg.de/license).
  • Unzip and copy the content of the *models* folder into the extra_data/mano folder

Install SMPL-X

Follow the instructions below to install SMPL-X

Download datasets

HO-3D

Download the dataset following the instructions on the official project webpage.

This code expects to find the ho3d root folder at local_data/datasets/ho3d

Core50

Follow instructions below to setup the Core50 dataset
  • Download the Object models from ShapeNetCorev2
    • Go to https://shapenet.org and create an account
    • Go to the download ShapeNet page
    • You will need the "Archive of ShapeNetCore v2 release" (~25GB)
    • unzip to local_data folder by adapting the command
      • unzip /path/to/ShapeNetCore.v2.zip -d local_data/datasets/ShapeNetCore.v2/

Running the Code

Check installation

Make sure your file structure after completing all the Setup steps, your file structure in the homan folder looks like this.

# Installed datasets
local_data/
  datasets/
    ho3d/
    core50/
    ShapeNetCore.v2/
    epic/
# Auxiliary data needed to run the code

Start fitting

Core50

Step 1

  • Pre-processing images
  • Joint optimization with coarse interaction terms
python fit_vid_dataset.py --dataset core50 --optimize_object_scale 0 --result_root results/core50/step1

Step 2

  • Joint optimization refinement
python fit_vid_dataset.py --dataset core50 --split test --lw_collision 0.001 --lw_contact 1 --optimize_object_scale 0 --result_root results/core50/step2 --resume results/core50/step1

HO3d

Step 1

  • Pre-processing images
  • Joint optimization with coarse interaction terms
python fit_vid_dataset.py --dataset ho3d --split test --optimize_object_scale 0 --result_root results/ho3d/step1

Step 2

  • Joint optimization refinement
python fit_vid_dataset.py --dataset ho3d --split test --lw_collision 0.001 --lw_contact 1 --optimize_object_scale 0 --result_root results/ho3d/step2 --resume results/ho3d/step1
