Hi @Nartmangnourt98

In rviz, you can use the Camera window rviz/DisplayTypes/Camera - ROS Wiki

This window displays an image from a camera with the visualized world rendered behind it.

Let me know if you can publish the output like the video.

Best,
Raffaello

Hey Raffaello,

thank you so much for you response. I really appreciate your time.
I want to show the observations point cloud (colourful dots) inside the image camera window.

Is there any code for that ? I guess you use OpenCV for that?

Best wishes

No, you don’t need to use anything, just set up rviz.

When you visualize the pointcloud changing in a more colorful way changing the parameters:

  • Channel
  • Billboard Size

Another option if you don’t want to use rviz, you can use foxglove
