Cannot display image in rqt and rviz #106
Comments
See if topics are echoed Rostopic list Look for camera topics Then rostopic echo /camera/image_raw* If you see data, rqt-image view should list these, and you select them. If no data, then you have either a network or loading issue. If there are network issues you will see no data in other sensor topics. Good luck. |
I failed using a WSL system for this. I successfully made it work on my Linux remote PC now. But any idea to fix this issue on wsl. |
I have the same problem. I listed the published topics and echo them. They are there. But I can't view on rviz and rqt by WSL and XLaunch. Have you solved it? |
Make sure both ROS_IP and ROS_MASTER_URI are expressed as IP numbers, not
named.
Example on workstation:
export ROS_IP=10.0.0.24,
export ROS_MASTER_URI=http://10.0.0.105:11311

Hello,
My Turttlebot3 waffle_pi was configured with Ubuntu Mate 18.04 32-bit and melodic ROS. I installed this raspicam_node as your instructions but modified a bit as this issue suggest #102 which just skip the skip the --rosdistro=kinetic option.
It built well but when i run it, no image showed in rqt.

[REMOTE PC]
roscore
[TURTLEBOT1]
roslaunch turtlebot3_bringup turtlebot3_rpicamera.launch
or
roslaunch raspicam_node camerav2_1280x960.launch
[REMOTE PC]
roslaunch turtlebot3_bringup turtlebot3_remote.launch
[REMOTE PC]
rqt_image_view
Does not show any camera input (shows some gradient)
Can you help about this issue? Thanks a lot.
