  • Turtlebot3 from Robotis
  • Ubuntu 18.04
  • ROS Melodic
  • Raspi Camera installed

I have the raspbery pi camera set up well enough so that when I run rqt_image_view I see the image. Oddly the topic is something like /raspicam_node/image/compressed_mouse_left . No idea what mouse_left means in this context.

Rostopic List shows:


When I specify node=/raspicam_node/image I get the closest. (Note that rqt_image shows the image fine and mentions a weird topic: "/raspicam_node/image/compressed_mouse_left" which doesn't work in Riz.)

The closest I get Rviz to work with the camera is when i specify topic raspicam_node/image.

Then in the RVIz box I see:

Status: Warn
Image: No Image Received
Camera Info: received
Topic: OK

And the image area in RVIz is just black! What am I missing?

"/raspicam_node/image/compressed_mouse_left" -- really? Where is that coming from?

Yes I did run the right one. Note that rqt_image shows the image fine and mentions a weird topic: "/raspicam_node/image/compressed_mouse_left".

I've updated the main question with more details.
