Raspicam with Rviz
- 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 rqtimageview I see the image. Oddly the topic is something like /raspicamnode/image/compressedmouseleft . No idea what mouseleft means in this context.
Rostopic List shows:
/raspicam_node
/raspicam_node/camera_info
/raspicam_node/image/compressed
/raspicam_node/parameter_descriptions
/raspicam_node/parameter_updates
When I specify node=/raspicamnode/image I get the closest. (Note that rqtimage shows the image fine and mentions a weird topic: "/raspicamnode/image/compressedmouse_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:
Camera:
Status: Warn
Image: No Image Received
Camera Info: received
Topic: OK
And the image area in RVIz is just black! What am I missing?

Is that different from what I get via the normal install via ros.org?

Seems to be the same Did you follow the instructions https://github.com/UbiquityRobotics/raspicam_node/blob/kinetic/README.md
Did you run the right launch file for you v1 or v2 camera

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.

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