The dataset is now available at Baidu net disk (code: bpi2) or google drive.

Introduction

In this work, we introduce a new 3D human-body model with a series of decoupled parameters that could freely control the generation of the body. Furthermore, we build a data generation system based on this decoupling 3D model, and construct an ultra dense synthetic benchmark UltraPose, containing around 1.3 billion corresponding points.

Installation

We recommend creating a clean conda environment and install all dependencies. You can do this as follows:

step1

conda create -n ultrapose python=3.7
conda activate ultrapose

step2

conda install pytorch=1.7.1 torchvision cudatoolkit=10.2 -c pytorch

step3

pip install ml-collections opencv-python imgaug visdom pycocotools Cython future h5py

You need to build python3 densepose for evaluation. You can do this as follows:

cd $UltraPoseDir/eval
make
cd $UltraPoseDir/eval/DensePoseData
bash get_eval_data.sh

Training

For single GPU training, please use default configurations by running:

python train.py --dataroot data/ultrapose

Besides, you can also use visdom to monitor the training process.

python -m visdom.server
python train.py --dataroot data/ultrapose --use_visdom

For multi-GPU training with default configurations, you can modify train_transformer.sh accordingly and run:

sh train_transformer.sh

Evaluation

python evaluation.py

Dataset

The dataset is now available from Baidu net disk (code: bpi2) or google drive.

Extract the data and put them under $UltraPoseDir/data.
