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.

RTAB-Map is released as binaries in the ROS distribution. For latest binaries, use ros-shadow-fixed repository.

• Kinetic

$ sudo apt-get install ros-kinetic-rtabmap-ros

• Jade

$ sudo apt-get install ros-jade-rtabmap-ros

• Indigo

$ sudo apt-get install ros-indigo-rtabmap-ros

• Hydro:

$ sudo apt-get install ros-hydro-rtabmap-ros

• Note that rtabmap_ros Hydro binaries are stuck at version 0.8.12. To use the latest version, see Build from source below.

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

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

This section shows how to install RTAB-Map ros-pkg on ROS Hydro/Indigo/Jade/Kinetic (Catkin build). RTAB-Map works only with the PCL 1.7, which is the default version installed with ROS Hydro/Indigo/Jade/Kinetic (Fuerte and Groovy are not supported).

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

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

• Make sure you don't have the binaries installed too (if you tried them before):

$ sudo apt-get remove ros-kinetic-rtabmap

0. Optional dependencies

• If you want SURF/SIFT on Indigo/Jade/Kinetic (Hydro has already SIFT/SURF), you have to build OpenCV from source to have access to nonfree module. Install it in /usr/local (default) and the rtabmap library should link with it instead of the one installed in ROS. 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 ros vision-opencv package yourself (and all ros packages depending on it) so it can link on OpenCV3.

• ROS (Qt, PCL, dc1394, OpenNI, OpenNI2, Freenect, g2o, Costmap2d, Rviz, Octomap, CvBridge). Note that I've found that latest g2o version built from source is faster (install libsuitesparse-dev before building g2o) and would be required to avoid some crashes.

$ sudo apt-get install libqt4-dev libpcl-1.7-all-dev libdc1394-dev ros-kinetic-openni-launch ros-kinetic-openni2-launch ros-kinetic-freenect-launch ros-kinetic-costmap-2d ros-kinetic-octomap-ros ros-kinetic-g2o ros-kinetic-rviz ros-kinetic-cv-bridge

  * [GTSAM](https://collab.cc.gatech.edu/borg/gtsam): Follow installation instructions from [here](https://collab.cc.gatech.edu/borg/gtsam/#quickstart). RTAB-Map needs latest version from source (`git clone https://bitbucket.org/gtborg/gtsam.git`), it will not build with 3.2.1.
  
  * [cvsba](http://www.uco.es/investiga/grupos/ava/node/39): Follow installation instructions from [here](http://www.uco.es/investiga/grupos/ava/node/39). Their installation is not standard CMake, you need these extra steps so RTAB-Map can find it:
    ```bash
$ mkdir /usr/local/lib/cmake/cvsba 
$ mv /usr/local/lib/cmake/Findcvsba.cmake /usr/local/lib/cmake/cvsba/cvsbaConfig.cmake

• Freenect2: Follow installation instructions from here.

1. Install RTAB-Map standalone libraries. Add -DCMAKE_INSTALL_PREFIX=~/catkin_ws/devel to cmake command below if you want to install in your Catkin's devel folder without sudo. 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 -j4
$ sudo make install

2. 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

$ cd rtabmap
$ git pull origin master
$ cd build
$ make
$ make install

$ roscd rtabmap_ros
$ git pull origin master
$ cd ~/catkin_ws
$ catkin_make
