How to Use RTabMap, ROS, and BB2 Driver

  • Set up:
    1. Required packages:
      • sudo apt-get install ros-indigo-rtabmap-ros
      • sudo apt-get install ros-indigo-stereo-image-proc
      • sudo apt-get install ros-indigo-image-pipeline
    2. Download launch file on the bottom.
    3. In terminal, within the directory of the file, mv disparity_to_dep.launch /opt/ros/indigo/share/rtabmap_ros/launch
  • Execution:
    1. On the robot, run the stereo_camera node.
    2. On the server/robot, in a new terminal, run ROS_NAMESPACE=stereo_camera rosrun stereo_image_proc stereo_image_proc _approximate_sync:=True
    3. If run for the first time on the machine/laptop, adjust the parameters for the disparity map generation (real time): "rosrun rqt_reconfigure rqt_reconfigure"
      • OR add Disparity.cfg (see in bottom) to catkin_ws/src/image_pipeline/stereo_image_proc/cfg
      • ELSE please adjust according to the image of the parameters on the bottom
    4. Optional (disparity to depth -- not tested yet):
      1. On the server, in a new terminal, cd /opt/ros/indigo/share/rtabmap_ros/launch
      2. Run roslaunch rtabmap_ros disparity_to_dep.launch

  1. To view the disparity map alongside the disparity image, use: "rosrun image_view stereo_view stereo:=/stereo_camera image:=image_rect"
  2. To view the disparity map alone, use "rosrun image_view disparity_view image:=/stereo_camera/disparity"
  3. To view the depth_map use: "rosrun image_view image_view image:=/depth_raw" (HAS NOT BEEN TESTED)
  4. There's more information at the following links:
