TL;DR: LIO-EKF is a lightweight yet efficient LiDAR-inertial odometry system based on adaptive point-to-point registration and EKF.

1. Prerequisites

• Ubuntu OS (tested on 20.04)
• ROS

Follow ROS Noetic installation instructions for Ubuntu 20.04.

• Eigen 3.4

2. RUN LIO-EKF

2.1 Clone the repository and catkin_make

cd ~/catkin_ws/src
git clone git@github.com:YibinWu/LIO-EKF.git
cd ../
catkin_make
source ~/catkin_ws/devel/setup.bash

2.2 Download the datasets

• urbanNav
• m2dgr
