LOAM-Livox

A robust LiDAR Odemetry and Mapping (LOAM) package for Livox LiDAR

Loam-Livox is a robust, low drift, and real time odometry and mapping package for Livox LiDARs, significant low cost and high performance LiDARs that are designed for massive industrials uses. Our package address many key issues: feature extraction and selection in a very limited FOV, robust outliers rejection, moving objects filtering, and motion distortion compensation. We use Ceres-Solver for scan matching to avoid complicated differential geometry derivation. The codes are well structured and streamlined to improve readability and extendability.

In the development of our package, we reference to LOAM, LOAM_NOTED, and A-LOAM.

1. Prerequisites

1.1 Ubuntu and ROS

Ubuntu 64-bit 16.04 or 18.04. ROS Kinetic or Melodic. ROS Installation

1.2. Ceres Solver

Follow Ceres Installation.

1.3. PCL

Follow PCL Installation.

2. Build

Clone the repository and catkin_make:

    cd ~/catkin_ws/src
    git clone https://github.com/hku-mars/loam_livox.git
    cd ../
    catkin_make
    source ~/catkin_ws/devel/setup.bash

3. Directly run

Connect to your PC to Livox LiDAR (mid-40) by following Livox-ros-driver installation, then

    roslaunch loam_livox livox.launch

To improve the whole wise performance, we strongly recommend you to fresh your livox lidar with this firmware by following this tutorial.

4. Rosbag Example

4.1. Common rosbag

Download Our recorded rosbag and then

roslaunch loam_livox rosbag.launch
rosbag play YOUR_DOWNLOADED.bag

4.1. Large-scale rosbag

For large scale rosbag (For example HKUST_01.bag ), we recommand you launch with bigger line and plane resolution (using rosbag_largescale.launch)

roslaunch loam_livox rosbag_largescale.launch
rosbag play YOUR_DOWNLOADED.bag
