Installation

● LeGO-LOAM

$ cd ~/your_workspace/src
$ git clone https://github.com/RobustFieldAutonomyLab/LeGO-LOAM.git
$ cd ..
$ catkin build

● LIO-SAM

$ cd ~/your_workspace/src
$ git clone https://github.com/TixiaoShan/LIO-SAM.git
$ cd ..
$ catkin build

● LVI-SAM

$ cd ~/your_workspace/src
$ git clone https://github.com/TixiaoShan/LVI-SAM.git
$ cd ..
$ catkin build

● Trouble shooting for LVI-SAM

  • for OpenCV 4.X, edit LVI-SAM/src/visual_odometry/visual_loop/ThirdParty/DVision/BRIEF.cpp:53
// cv::cvtColor(image, aux, CV_RGB2GRAY);
cv::cvtColor(image, aux, cv::COLOR_RGB2GRAY);

How to run in Gazebo

● check each of config files in the folders: LeGO-LOAM, LIO-SAM, and LVI-SAM

Trouble shooting for Gazebo Velodyne plugin

  • When using CPU ray, instead of GPU ray, height - width should be interchanged, I used this script file
