3D Human Pose Estimation with Spatial and Temporal Transformers
This repo is the official implementation for CrossFormer: Cross Spatio-Temporal Transformer for 3D Human Pose Estimation
Our code is built on top of VideoPose3D.
Environment
The code is developed and tested under the following environment
- Python 3.8.2
- PyTorch 1.7.1
- CUDA 11.0
You can create the environment:
conda env create -f crossformer.yml
Dataset
Our code is compatible with the dataset setup introduced by Martinez et al. and Pavllo et al.. Please refer to VideoPose3D to set up the Human3.6M dataset (./data directory).
Evaluating pre-trained models
We provide the pre-trained 81-frame model (CPN detected 2D pose as input) here. To evaluate it, put it into the ./checkpoint
directory and run:
python run_crossformer.py -k cpn_ft_h36m_dbb -f 81 -c checkpoint --evaluate best_epoch44.4.bin
We also provide pre-trained 81-frame model (Ground truth 2D pose as input) here. To evaluate it, put it into the ./checkpoint
directory and run:
python run_crossformer.py -k gt -f 81 -c checkpoint --evaluate best_epoch_gt_28.5.bin
Training new models
- To train a model from scratch (CPN detected 2D pose as input), run:
python run_crossformer.py -k cpn_ft_h36m_dbb -f 27 -lr 0.00004 -lrd 0.99
- To train a model from scratch (Ground truth 2D pose as input), run:
python run_crossformer.py -k gt -f 81 -lr 0.0004 -lrd 0.99
81 frames achieves 28.5 mm (MPJPE).
Visualization and other functions
We keep our code consistent with VideoPose3D. Please refer to their project page for further information.
