demo_1

demo_2

Installation

conda create python=3.7 --name jotr
conda activate jotr
pip install torch==1.8.0 torchvision==0.9.0
sh requirements.sh

Data Preparation

We prepare the data in a samilar way as 3DCrowdNet. Please refer to 3DCrowdNet for dataset, SMPL model, VPoser model, and backbone pre-trained weights.

Download the annotations of 3DPW-PC, 3DPW-OC.

Download checkpoint of JOTR from here.

The data directory should be organized as follows:

${ROOT}

|-- 3dpw_best_ckpt.pth.tar
|-- 3dpw-crowd_best_ckpt.pth.tar
|-- 3dpw-oc_best_ckpt.pth.tar
