This repository contains the source code and additional configuration files to reproduce the results of our work presented in the Robot 2022 international conference:
D. Alejo, R. Rey, J. A. Cobano, F. Caballero and L. Merino, "Data fusion of low-cost RADAR and LIDAR for reliable ground robotlocalization under low-visibility conditions". In D. Tardioli, V. Matellan, G. Heredia, M.F. Silva, and L. Marques, editors, ROBOT2022: Fifth Iberian Robotics Conference, Advances in Intelligent Systems and Computing, pp. 301–313, Springer International Publishing, 2023.
In this paper, we have designed and implemented a new method for fusing radar and lidar information. The method has been implemented mainly in the source file: src/sensor_fusion/lidar_radar_fusion_dbscan.cpp
The dataset used in this paper can be downloaded at:
The utilities of this repository have been programmed on a Linux 18.04 distribution and ROS melodic. They have also been tested in Ubuntu 20.04 and ROS noetic. Please refer to the ROS wiki for details on installation and the creation of a catkin workspace.
- Cloud concatenator: https://github.com/robotics-upo/cloud_concatenator
- pcl_ros:
sudo apt install ros-$ROS_DISTRO-pcl-ros
- pointcloud_to_laser_scan
sudo apt install ros-$ROS_DISTRO-pointcloud-to-laserscan

- odom_to_tf: https://github.com/robotics-upo/odom_to_tf
You can download the repository and execute ./scripts/install_fusion_dependencies.sh
from the source directory of a catkin workspace. It will install APT packages and download the necessary repos to avoid doing it manually. In addition it asks you if you want to download the dataset.
Once you download our dataset into the folder "${HOME}/radar_fusion_bags", you can launch the experiment batch presented in the ICRA paper as follows (for ten repetitions):
rosrun radar_experiments experiment_batch.sh 1 10
It will run the fusion node and launch a rviz visualization window where you can select which radar scans you want to visualize.
