rtabmap_ros Build Status docker

RTAB-Map's ROS package.

For more information, demos and tutorials about this package, visit rtabmap_ros page on ROS wiki.

For the RTAB-Map libraries and standalone application, visit RTAB-Map's home page or RTAB-Map's wiki.

Installation

ROS2 distribution

Under construction: see ros2 branch.

ROS distribution

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

  • Noetic 
    $ sudo apt install ros-noetic-rtabmap-ros
  • Melodic 
    $ sudo apt install ros-melodic-rtabmap-ros
  • Kinetic 
    $ sudo apt-get install ros-kinetic-rtabmap-ros
  • Indigo 
    $ sudo apt-get install ros-indigo-rtabmap-ros
    • For armhf architecture, ros-indigo-rtabmap-ros is not available. Install ros-indigo-rtabmap and build from source rtabmap_ros using the indigo-devel branch. 
      $ cd catkin_ws
$ git clone -b indigo-devel https://github.com/introlab/rtabmap_ros.git src/rtabmap_ros
$ catkin_make -j1

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 Hydro/Indigo/Jade/Kinetic/Lunar/Melodic/Noetic (Catkin build). RTAB-Map works only with the PCL >=1.7, which is the default version installed with ROS Hydro/Indigo/Jade/Kinetic/Lunar/Melodic/Noetic (Fuerte and Groovy are not supported).

  • The next instructions assume that you have set up your ROS workspace using this tutorial. I will use noetic prefix for convenience, but it should work with Hydro, Indigo, Jade, Kinetic, Lunar and Melodic. The workspace path is ~/catkin_ws and your ~/.bashrc contains:

    $ source /opt/ros/noetic/setup.bash
$ source ~/catkin_ws/devel/setup.bash

  1. Required dependencies

    • The easiest way to get all them (Qt, PCL, VTK, OpenCV, ...) is to install/uninstall rtabmap binaries: 
      $ sudo apt install ros-noetic-rtabmap ros-noetic-rtabmap-ros
$ sudo apt remove ros-noetic-rtabmap ros-noetic-rtabmap-ros

  2. Optional dependencies

    • If you want SURF/SIFT on Indigo/Jade/Melodic/Noetic (Hydro/Kinetic has already SIFT/SURF), 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 Indigo, I recommend to use latest 2.4 version (2.4.11) and build it from source following these instructions. RTAB-Map can build with OpenCV3+xfeatures2d module, but rtabmap_ros package will have libraries conflict as cv_bridge is depending on OpenCV2. If you want OpenCV3+, you should build vision-opencv package yourself (and all ros packages depending on it) so it can link on OpenCV3+.
      • On Kinetic/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-noetic-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.

  3. 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

  4. 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.

Build from source for Nvidia Jetson

  • For Jetpack 4 (Ubuntu 18.04 with ROS Melodic), see this post.
  • For Jetpack 3 (Ubuntu 16.04 with ROS Kinetic), see this post.
