There is a description for each parameter. One way to know RTAB-Map's parameters is to look at this file : Parameters.h. The RTAB-Map's parameters are those from the RTAB-Map library. The ROS parameters are for connection stuff to interface the RTAB-Map library with ROS.
There are two set of parameters: ROS and RTAB-Map's parameters. To get a 3D point cloud or a 2D occupancy grid of the environment, subscribe to cloud_map or grid_map topics. The default location of the RTAB-Map database is "~/.ros/rtabmap.db" and the workspace is also set to "~/.ros". The online output of the node is the local graph with the latest added data to the map. This is where the graph of the map is incrementally built and optimized when a loop closure is detected. It is a wrapper of the RTAB-Map Core library. $ roslaunch rtabmap_ros demo_appearance_mapping.launch localization:=trueįor more videos and information about the loop closure detection approach used in RTAB-Map, visit RTAB-Map on IntRoLab.Īll sensor_msgs/Image topics use image_transport. This can be also used in localization mode: $ rostopic echo /rtabmap/info/loopClosureIdĪ "0" means no loop closure detected. If you only need the ID of the matched past image of a loop closure, you can do that: 
The GUI shows a plenty of information about the loop closures detected.
$ roslaunch rtabmap_ros demo_appearance_mapping.launch. Set video_or_images_path parameter of camera node in the launch file below accordingly. #Grid mapping approach how to
There is no bag recorded for this demo but how to reproduce this setup is described in the tutorial StereoOutdoorNavigation.Īppearance-based loop closure detection-only $ roslaunch rtabmap_ros demo_stereo_outdoor.launch.It is also shown how to create 2D occupancy grid map for navigation. Visit the tutorial StereoOutdoorMapping for detailed information.
There is no bag recorded for this demo but how to reproduce this setup is described on the page IROS 2014 Kinect Challenge of the RTAB-Map's wiki. $ rosbag play -clock demo_find_object.bag
$ roslaunch rtabmap_ros demo_find_object.launch. $ roslaunch rtabmap_ros demo_multi-session_mapping.launchįind-Object's ros-pkg find_object_2d should be installed. Launch: demo_multi-session_mapping.launch You may need to do this after starting the first bag with "-pause" so that rtabmap node is initialized to avoid a "service /reset cannot be called" error. Updated 8: fixed TF quaternion not normalized errorįor the first launch, you can do "Edit->Delete memory" to make sure that you start from a clean memory. Updated 1: fixed TF rotation of the camera $ roslaunch rtabmap_ros demo_robot_mapping.launch rviz:=true rtabmapviz:=falseĭetailed results are shown on the Multi-session page on RTAB-Map's wiki.įor this demo, you will need the ROS bags of five mapping sessions:. #Grid mapping approach download
You will need to click "Edit->Download Map" on the GUI to download the map from the core node. Note that the GUI node doesn't download automatically the map when started. $ roslaunch rtabmap_ros demo_robot_mapping.launch localization:=true.$ roslaunch rtabmap_ros demo_robot_mapping.launchĪfter mapping, you could try the localization mode:.This tutorial shows how to add user data during mapping that will be saved directly in RTAB-Map's database for convenience.įor this demo, you will need the ROS bag demo_mapping.bag (295 MB, fixed camera TF 8, fixed not normalized quaternions 4, fixed compressedDepth encoding format 7, fixed odom child_frame_id not set 2).

This tutorial shows multiple RTAB-Map configurations that can be used on your robot. This tutorial shows how to integrate autonomous navigation with RTAB-Map in context of outdoor stereo mapping. This tutorial shows how to do stereo mapping with RTAB-Map. This tutorial shows how to do mapping on a remote computer. This tutorial shows how to use rtabmap_ros out-of-the-box with a stereo camera in mapping mode or localization mode. This tutorial shows how to use rtabmap_ros out-of-the-box with a Kinect-like sensor in mapping mode or localization mode. The tutorials and demos show some examples of mapping with RTAB-Map. This package can be used to generate a 3D point clouds of the environment and/or to create a 2D occupancy grid map for navigation. This package is a ROS wrapper of RTAB-Map (Real-Time Appearance-Based Mapping), a RGB-D SLAM approach based on a global loop closure detector with real-time constraints. Appearance-based loop closure detection-only.
