Installation

ROS2 distribution

Under construction: see ros2 branch.

ROS distribution

RTAB-Map is released as binaries in the ROS distribution.

sudo apt install ros-$ROS_DISTRO-rtabmap-ros

When launching rtabmap_ros's nodes, if you have the error error while loading shared libraries..., try ldconfig or add the next line at the end of your ~/.bashrc to fix it:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/ros/noetic/lib/x86_64-linux-gnu

Docker

Go to docker directory for an example.

Build from source

This section shows how to install RTAB-Map ros-pkg on ROS Melodic/Noetic (Catkin build).

The next instructions assume that you have set up your ROS workspace using this tutorial. The workspace path is ~/catkin_ws and your ~/.bashrc contains:
```
$ source /opt/ros/$ROS_DISTRO/setup.bash
$ source ~/catkin_ws/devel/setup.bash
```

Required dependencies

The easiest way to get all them (Qt, PCL, VTK, OpenCV, ...) is to install/uninstall rtabmap binaries:

sudo apt install ros-$ROS_DISTRO-rtabmap ros-$ROS_DISTRO-rtabmap-ros
sudo apt remove ros-$ROS_DISTRO-rtabmap ros-$ROS_DISTRO-rtabmap-ros

Optional dependencies
- If you want SURF/SIFT on Melodic/Noetic, you have to build OpenCV from source to have access to xfeatures2d and nonfree modules (note that SIFT is not in nonfree anymore since OpenCV 4.4.0). Install it in /usr/local (default) and rtabmap library should link with it instead of the one installed in ROS.
  - On Melodic/Noetic, build from source with xfeatures2d module (and nonfree module if needed) the same OpenCV version already installed on the system. You will then avoid breaking cv_bridge with rtabmap_ros. If you want to install a more recent OpenCV version, I recommend to uninstall libopencv* libraries (with all ros packages depending on it) and rebuild all those ros packages in your catkin workspace (to make sure cv_bridge is linked on the OpenCV version you just compiled).
- g2o: Should be already installed by ros-$ROS_DISTRO-libg2o.
- GTSAM: Install via PPA to avoid building from source. If you install from source, make sure to build with cmake -DGTSAM_BUILD_WITH_MARCH_NATIVE=OFF -DGTSAM_USE_SYSTEM_EIGEN=ON.
- libpointmatcher: Recommended if you are going to use lidars. Follow their instructions to install. Should be alread installed by ros-$ROS_DISTRO-libpointmatcher.

Install RTAB-Map standalone libraries. Do not clone in your Catkin workspace.

cd ~
git clone https://github.com/introlab/rtabmap.git rtabmap
cd rtabmap/build
cmake ..  [<---double dots included]
make -j6
sudo make install

Install RTAB-Map ros-pkg in your src folder of your Catkin workspace.
```
cd ~/catkin_ws
git clone https://github.com/introlab/rtabmap_ros.git src/rtabmap_ros
catkin_make -j4
```
- Use catkin_make -j1 if compilation requires more RAM than you have (e.g., some files require up to ~2 GB to build depending on gcc version).
- Options:
  - Add -DRTABMAP_SYNC_MULTI_RGBD=ON to catkin_make if you plan to use multiple cameras.
  - Add -DRTABMAP_SYNC_USER_DATA=ON to catkin_make if you plan to use user data synchronized topics.
