# Overlap-based 3D LiDAR Monte Carlo Localization
This repo contains the code for our IROS2020 paper: Learning an Overlap-based Observation Model for 3D LiDAR Localization.
It uses the [OverlapNet](https://github.com/PRBonn/OverlapNet) to train an observation model for Monte Carlo Localization and achieves global localization with 3D LiDAR scans.
Developed by [Xieyuanli Chen](https://www.ipb.uni-bonn.de/people/xieyuanli-chen/) and [Thomas Läbe](https://www.ipb.uni-bonn.de/people/thomas-laebe/).
Localization results of overlap-based Monte Carlo Localization.

## Dependencies
We are using standalone Keras with a TensorFlow backend as a library for neural networks.
The code was tested with Ubuntu **18.04** with its standard python version **3.6**.
In order to do training and testing on a whole dataset, you need an Nvidia GPU.
To use a GPU, first you need to install the Nvidia driver and CUDA, so have fun!
- CUDA Installation guide: [link](https://docs.nvidia.com/cuda/cuda-installation-guide-linux/index.html)
- System dependencies:
```bash
sudo apt-get update
sudo apt-get install -y python3-pip python3-tk
sudo -H pip3 install --upgrade pip
```
- Python dependencies (may also work with different versions than mentioned in the requirements file)
```bash
sudo -H pip3 install -r requirements.txt
```
- OverlapNet: To use this implementation, one needs to clone OverlapNet to the local folder by:
```bash
git clone https://github.com/PRBonn/OverlapNet
```
## How to use
#### Quick use
For a quick demo, one could download the [feature volumes](https://www.ipb.uni-bonn.de/html/projects/overlap_mcl/feature_volumes.zip) and pre-trained sensor [model](https://www.ipb.uni-bonn.de/html/projects/overlap_mcl/model.weight), extract the feature volumes in the `/data` folder following the recommended [data structure](data/README.md), and then run:
```bash
cd src/
python3 main_overlap_mcl.py
```
One could then get the online visualization of overlap-based MCL as shown in the gif.
#### More detailed usage
For more details about the usage and each module of this implementation, one could find them in MCL [README.md](src/README.md).
#### Train a new observation model
To train a new observation model, one could find more information in prepare_training [README.md](src/prepare_training/README.md).
