Does anyone has any experience building a ROS system that could do SLAM and navigation task concurrently?

  • Goal: 3D + 2D SLAM(visualize in same gui) + Auto-navigation
  • Hardware:
    • robot: turtlebot2
    • sensor: kinectv2

I found this page. Chapter "2.2 Kinect + Odometry + Fake 2D laser from Kinect" seems similar to my requirement, but it lacks some details.

My current progress is I successfully convert kinectv2 data to fake laser scan and feed into rtabmap.

I wonder that:

  1. How can I show the 2D map build by rtabmap_ros?
  2. How to combine 2D and 3D map into same GUI space?

Which version of rtabmap are you using? Kinetic binaries?
