# VoxelKP: A Voxel-based Network Architecture for Human Keypoint Estimation in LiDAR Data

We present VoxelKP, a novel fully sparse network architecture tailored for human keypoint estimation in LiDAR data. We achieved the state-of-the-art performances without additional data.

## Performance Demo

[![Watch the video](https://img.youtube.com/vi/u-xHv_OAO0M/hqdefault.jpg)](https://youtu.be/u-xHv_OAO0M)

## Installation

Please refer to the installation of `OpenPCDet`.

## Getting Started

Please refer to [GETTING_STARTED.md](docs/GETTING_STARTED.md) to learn more usage about this project.

This is the inference only code.

Checkpoints can be downloaded from [here](https://huggingface.co/shijianjian/VoxelKP).

```bash
$ cd tools
$ python waymo_visualizer.py --ckpt CHECKPOINT
```

## Train

1. Prepare dataset, referring to [OpenPCDet](https://github.com/open-mmlab/OpenPCDet/blob/master/docs/GETTING_STARTED.md).

2. Install the module for compling.
```bash
$ pip install -e .
```

3. The training script.

```bash
$ cd tools
$ python train.py  --cfg_file ./cfgs/waymo_models/kp_effv2next4_voxelnext_iou_aug_bev_channel.yaml --epochs 20
```

if using multiple GPUs

```bash
$ bash scripts/dist_train.sh 8 --cfg_file ./cfgs/waymo_models/kp_effv2next4_voxelnext_iou_aug_bev_channel.yaml --epochs 36 --workers 0
```

## Benchmarks

There is a limited number of relevant research for this task. Most of the prior works utilize additional training data beyond the 3D keypoint data within the Waymo dataset. To provide a fair comparison, we need to consider approaches that use extra data and those that rely solely on Waymo ground truth separately.

## Experiment Results

We report the full spectrum of the evaluation, including MPJPE, OKS@AP, and PEM.

Our visual results show that our VoxelKP offers improved keypoint estimation with precise locations and fewer false positives.
