VirtualPose: Learning Generalizable 3D Human Pose Models from Virtual Data (ECCV 2022)

Introduction

This is the official Pytorch implementation for: VirtualPose: Learning Generalizable 3D Human Pose Models from Virtual Data

Installation

pip install -r requirement.txt
python setup.py develop

Data preparation

The directory tree should look like this:

• Download MSCOCO parsed data [data]

• Download MuCo parsed and composited data [data] provided by [RootNet]

• Download MuPoTS parsed data [images][annotations]

• Download Panoptic by following the instructions in panoptic-toolbox and extract them under ${ROOT}/data/panoptic-toolbox/data. Download[annotations] provided by [HMOR] and put them under ${ROOT}/data/panoptic-toolbox/$, and run python pack.py.

• Download pretrained ResNet-152 model pose_resnet_152_384x288.pth.tar provided by [Simple Baselines] and put it under ${ROOT}/models/$.

Training

We use 4 NVIDIA V100 with 32GB GPU memory for training.

CMU Panoptic dataset

Train the 2D pose estimation and human detection backbone with 2 gpus:

python run/train_3d.py --cfg configs/coco/backbone_res152_mix_panoptic.yaml --gpus 2

Train the root depth estimator and 3D pose estimator with 4 gpus:

python run/train_3d.py --cfg configs/panoptic/synthesize_full.yaml --gpus 4

MuCo-3DHP and MuPoTS-3D datasets

Train the 2D pose estimation and human detection backbone with 2 gpus:

python run/train_3d.py --cfg configs/coco/backbone_res152_mix_muco.yaml --gpus 2

Train the root depth estimator and 3D pose estimator with 4 gpus:

python run/train_3d.py --cfg configs/muco/synthesize_full.yaml --gpus 4

Evaluation

Our pre-trained models are available for download from Google drive or Onedrive.

CMU Panoptic dataset

Inference with 4 gpus:

python run/validate_3d.py --cfg configs/panoptic/synthesize_full_inference.yaml --gpus 4

MuCo-3DHP and MuPoTS-3D datasets

Inference with 4 gpus:

python run/validate_3d.py --cfg configs/muco/synthesize_full_inference.yaml --gpus 4

The results are in ${ROOT}/mupots_results/$, then use the evaluation code provided by MuPoTS-3D dataset to evaluate the results.
