rgbdslam_freiburg: rgbdslam

Package Summary

This package can be used to register the point clouds from RGBD sensors such as the kinect or stereo cameras. The rgbdslam node can be connected easily to an octomap_server node to create a memory-efficient 3D map.

Package Summary

rgbdslam (v2) is a SLAM solution for RGB-D cameras. It provides the current pose of the camera and allows to create a registered point cloud or an octomap. It features a GUI interface for easy usage, but can also be controlled by ROS service calls, e.g., when running on a robot. For installation and usage instructions see the README file of the github repository.

This page describes the RGB-D SLAM system for ROS Fuerte. There is a successor, rgbdslam_v2 for ROS Hydro and Indigo. See README.

For the electric version and many details that still hold true, see this page.

Download and Installation

If you are not a ROS user yet, follow the instructions at the bottom of this page.

Download rgbdslam with the following command to your ros workspace.

svn co http://alufr-ros-pkg.googlecode.com/svn/trunk/rgbdslam_freiburg

ROS needs to be aware of the folder into which you download rgbdslam_freiburg! Make sure that the folder containing rgbdslam_freiburg is in your ROS_PACKAGE_PATH (see ros workspace for how to modify the ROS_PACKAGE_PATH. It is a bad idea to put rgbdslam_freiburg into /opt/ros/fuerte/...). If properly configured "roscd rgbdslam" will take you to the rgbdslam package directory

If not yet installed, install rosdep first, then execute

rosdep update
rosdep install rgbdslam_freiburg

This should take care of all system dependencies (e.g. libg2o, octomap).

You can then compile it with

rosmake rgbdslam_freiburg

which will take a while. If you encounter problems, here is an example build logfile for a successful build for reference (Revision 3949).

As mentioned in rgbdslam_electric, if ROS dependencies are still not met for some reason, you might need to install the following dependencies

sudo apt-get install libglew1.5-dev libdevil-dev libsuitesparse-dev


There are several example launch-files that set the parameters of RGB-D SLAM for certain use cases, a complete list of all options and their current settings can be found in the GUI: "Settings"->"View Current Settings". For a definitive list of all settings and the default values have a look at their quite readable definition in src/parameter_server.cpp.

I am still adapting the various use-case launch-files to fuerte and the new openni stack, so some of the launchfiles might not work correctly yet. You should get them running if you fiddle with the topics ("rostopic list" and "rosnode info" will help you. "rxgraph" is great too).


If you want to use RGB-D SLAM with a Kinect or Xtion Pro, you should install openni_launch. If you want to edit the saved point clouds you might want to install meshlab.

Most people seem to want the registered point cloud. It is by default sent out on /rgbdslam/batch_clouds when you command RGB-D SLAM to do so (see below). The clouds sent are actually the same as before, but the according transformation - by default from /map to /openni_camera - is sent out on /tf.

This is also the way the octomap_server gets the point clouds. Just make it listen to the mentioned topic and set the fixed frame_id to /map (See the launch file octomap_server.launch)


To start RGBDSLAM launch

  roslaunch rgbdslam kinect+rgbdslam.launch

Alternatively you can start the openni nodes and RGBDSLAM separately, e.g.:

  roslaunch openni_launch openni.launch
  rosrun rgbdslam rgbdslam

To capture models either press space to start recording a continuous stream or press enter to record a single frame. To reduce data redundancy, sequential frames from (almost) the same position are not included in the final model. The 3D visualization always shows the globally optimized model. Neighbouring points are triangulated except at missing values and depth jumps.

Usage via ROS service calls (possibly headless)

The RosUI is an alternative to the Grapical_UI and lets you use rgbdslam via service-calls. This allows you, e.g. to run the rgbdslam headless, for example on the PR2. The possible calls are:

See below for a detailed description of all options. To start the rgbdslam headless use the headless.launch:

        roslaunch rgbdslam headless.launch

Example service calls:

        rosservice call /rgbdslam/ros_ui frame # Capture single frames via
        rosservice call /rgbdslam/ros_ui_b pause false # Capture a stream of data
        rosservice call /rgbdslam/ros_ui send_all # Send point clouds with computed transformations (e.g., to rviz or octomap_server)
        rosservice call /rgbdslam/ros_ui_s save_cloud /tmp/mycloud.pcd # Save the registered pointclouds in the given file
        rosservice call /rgbdslam/ros_ui_s save_individual /tmp/filenameprefix # As above, but save every pointcloud in its own file

RGB-D SLAM has many options to customize its behavior. You can speed it up significantly by

However, the last three options and using ORB will probably decrease the accuracy.


RGB-D SLAM for "Not-yet" ROS Users

If you aren't using ROS yet and just want to use RGB-D SLAM on Ubuntu (tested with Ubuntu "precise pangolin" 12.04), here's an installation walkthrough:

# Better pick a mirror close to you.
# See http://ros.org/wiki/ROS/Installation/UbuntuMirrors
sudo sh -c '. /etc/lsb-release && echo "deb http://packages.ros.org/ros/ubuntu $DISTRIB_CODENAME main" > /etc/apt/sources.list.d/ros-latest.list'

wget http://packages.ros.org/ros.key -O - | sudo apt-key add -

sudo aptitude update

# This will draw gigabytes from the network:
sudo apt-get install ros-fuerte-perception-pcl ros-fuerte-vision-opencv ros-fuerte-octomap-mapping python-rosdep

echo 'source /opt/ros/fuerte/setup.bash' >> ~/.bashrc

echo 'export ROS_PACKAGE_PATH=~/ros:$ROS_PACKAGE_PATH' >> ~/.bashrc

. ~/.bashrc

svn co http://alufr-ros-pkg.googlecode.com/svn/trunk/rgbdslam_freiburg ~/ros/rgbdslam_freiburg

sudo rosdep init

rosdep update

rosdep install rgbdslam_freiburg

roscd rgbdslam

# This will take a while:
rosmake rgbdslam_freiburg

If this reports no failures, you successfully installed the RGB-D SLAM system.

To use it with a Kinect/Xtion Pro you need to install the camera driver:

sudo apt-get install ros-fuerte-openni-launch

For usage, see above.
