2019-08-19 15:01:30 -0600 marked best answer RGB-D Handheld Mapping with RealSense R200

I was following the RGB-D Handheld Mapping tutorial . First I ran the following command

$ roslaunch realsense_camera r200_nodelet_default.launch

While the realsense_camera node is running, in a new tab I ran

$ roslaunch rtabmap_ros rtabmap.launch rtabmap_args:="--delete_db_on_start" depth_topic:=/camera/depth_registered/sw_registered/image_rect_raw

The RTABMAP GUI is launched as expected but there is no image.

In the terminal that I launched the RTABMAP GUI, I am receiving the following warning.

[ WARN] [1532462055.394145038]: /rtabmap/rgbd_odometry: Did not receive data since 5 seconds! Make sure the input topics are published ("$ rostopic hz my_topic") and the timestamps in their header are set. 
/rtabmap/rgbd_odometry subscribed to (approx sync):
   /camera/rgb/image_rect_color,
   /camera/depth/image_raw,
   /camera/rgb/camera_info

Same thing happens when I run

$ roslaunch rtabmap_ros rtabmap.launch rtabmap_args:="--delete_db_on_start" depth_topic:=/camera/depth/points/image_raw

Can you help me solve this issue? Thank you.

I am running Ros Kinetic on Ubuntu 16.04 64-bit machine.

Edit

The published topics are:

I think the RTABMAP GUI is not looking for the right topic; there is nothing matching "/camera/depth_registered/sw_registered/image_rect_raw". What should I change the

$ roslaunch rtabmap_ros rtabmap.launch rtabmap_args:="--delete_db_on_start" depth_topic:=/camera/depth_registered/sw_registered/image_rect_raw

command with?

Edit 2

As Martin suggested, I tried running

$ roslaunch rtabmap_ros rtabmap.launch rtabmap_args:="--delete_db_on_start" depth_topic:=/camera/depth/image_raw

Again, there's no image in the GUI. I also ran "rostopic hz /camera/depth/image_raw" and got:

$ rostopic hz /camera/depth/image_raw

I was wondering which line extraction algorithms are used in gmapping and cartographer packages?

I couldn't find this information on the ROS wiki websites.

Some of the possible options are

  • Split-and-merge
  • Hough-transform
  • RANSAC
  • Incremental
  • Line-regression
  • Expectation maximization

Thanks!

2018-07-23 18:49:47 -0600 marked best answer The Intel RealSense R200 camera is not detected by the Turtlebot3 (Waffle)

Hello all,

I am trying to do 3D SLAM using the R200 camera and Turtlebot3 Waffle. I installed the Intel® RealSense™ package following the steps given in http://emanual.robotis.com/docs/en/pl...

When I ran

roslaunch realsense_camera r200_nodelet_rgbd.launch

I receive the following error:

[ERROR] [1530659146.559707562]: /camera/driver - No cameras detected!

The camera was connected to Netmate USB 3.0 (4 port) hub. I tried connecting it directly but I am still getting the same error. Some additional information are:

I am not running inside a VM. The PC and OS specs are:

  • Ubuntu 16.04.4 LTS \n \l
  • 4.13.0-45-generic
  • 64-bit machine

Is the camera recognized on some another platform? I didn't try this particular camera with another device other than the Turtlebot I have.

I am using the short USB cable provided with the camera device.

In here under title Installation Troubleshooting this particular error is mentioned. But as far as I understood, the solution provided applies to the case where the camera is connected to a PC not a Turtlebot, hence I didn't try the provided solution.

Any help is appreciated.
