This repo contains LiDAR-only visual SLAM developped by Kitware, as well as ROS and ParaView wrappings for easier use.
It has been successfully tested on data from several common LiDAR sensors:
- Velodyne (VLP-16, VLP-32c, HDL-32, HDL-64, VLS-128)
- Ouster (OS0/1/2-32/64/128)
- RoboSense (RS-LiDAR-16)
- Hesai (Pandar128)
Have a look at our SLAM demo video!
This codebase is under active development. If you're interested by new features, new sensors' support or any project that could be using this SLAM, do not hesitate to contact us at [email protected].

(*) optional dependencies :
- If G2O is not available (or disabled), LidarSlam lib will still be compiled, but without pose graph optimization features.
- If OpenMP is available, it is possible to use multi-threading to run some SLAM steps in parallel and achieve higher processing speed.
To build only LidarSlam lib, just cd
to this repo root dir and run :
mkdir build
cd build
cmake .. -DCMAKE_BUILD_TYPE=RelWithDebInfo
make
make install
The LidarSlam lib has been tested on Linux, Windows and OS X.
Ensure all LidarSlam dependencies are respected. Specific ROS packages dependencies are listed in the table below along with the version used during development and testing.
Dependency | Tested Version | Install (sudo apt-get install <pkg> ) |
---|---|---|
ROS | melodic | ros-melodic-desktop-full and tutorial |
velodyne_pcl | 1.6.1 | ros-noetic-velodyne-pcl or git repo |
gps_common | 0.3.0 | ros-$ROS_DISTRO-gps-common |
geodesy | 0.5.3 | ros-$ROS_DISTRO-geodesy |
Please note that the ROS Velodyne driver with minimum version 1.6 is needed.
Be careful, this ROS Velodyne driver 1.6 is not backward-compatible with previous versions.
If you're running on Ubuntu 20 / ROS Noetic, you can install the new Velodyne driver using the command sudo apt install ros-noetic-velodyne ros-noetic-velodyne-pcl
.
If running on previous versions of Ubuntu/ROS (18/Melodic and below), you need to compile this driver from source : just clone the git repo in your catkin worskpace sources, it will be automatically built with next catkin_make
.
Clone this git repo directly into your catkin directory, and run catkin_make -DCMAKE_BUILD_TYPE=RelWithDebInfo
or catkin_make -DCMAKE_BUILD_TYPE=Release
(to turn on optimizations, highly recommended when using Eigen). It will automatically build LidarSlam lib before ROS packages.
The ROS wrapping has been tested on Linux only.
roslaunch lidar_slam slam.launch
roslaunch lidar_slam slam.launch gps:=true # if GPS/SLAM calibration has to be run
See ros_wrapping/lidar_slam/README.md for more details.
Ensure all LidarSlam dependencies are respected. Specific dependencies are listed in the table below along with the version used during development and testing.
Dependency | Tested Version |
---|---|
ParaView | 5.4 and 5.6 |
Be careful to use and link to the same libraries as ParaView/LidarView's (especially with VTK, Eigen, PCL, Ceres, nanoflann, etc.). Otherwise, if different flags or modules were enabled, some troubles may arise at build time, or it could lead to version mismatch and segfault at runtime.
For example, if PCL is built with pcl_visualization
module, it must link to the same VTK than the one used by ParaView.
To build LidarSlam lib and this ParaView plugin LidarSlamPlugin, just cd
to this repo root dir and run :
mkdir build
cd build
cmake .. -DCMAKE_BUILD_TYPE=RelWithDebInfo -DSLAM_PARAVIEW_PLUGIN:BOOL=ON
make
make install
The LidarSlamPlugin Paraview wrapping has been tested on Linux, Windows and OS X.
- Open ParaView
- Tools tab > Manage Plugins > Load New
- Browse to the
<install>/lib/
dir and selectlibLidarSlamPlugin.so
orLidarSlamPlugin.dll
- Load LiDAR frames and LiDAR calibration to use
- Select the frames in the Pipeline Browser, instantiate a SLAM filter, and apply it.
Currently, all features are not available in ParaView plugin. Features such as GPS/LiDAR calibration, pose graph optimization or temporal logging are only supported in ROS wrapping. However, ParaView plugin is useful to play with SLAM, interactively try out parameters, visualize and export results.
This LidarSlamPlugin is natively included in LidarView. For more detailed information on how to enable and use SLAM filter in LidarView, see paraview_wrapping/doc/How_to_SLAM_with_LidarView.md.
Pre-built binaries of LidarView with this SLAM plugin are available for download here.
