I would like to simulate point cloud readings in the environment on a quadcopter and tried to use the gz\_x500\_depth vehicle for software in the loop.

I’m able to see the topics /depth\_camera and /depth\_camera/points, but I’m unable to display the pointcloud in gazebo. Am I missing some steps?

Here are my screenshots for reference (I also added a box in the default world):

The command “gz topic -e -t /depth\_camera/points” shows a bunch of numbers:

I’m using Ubuntu 22.04 Jammy Jellyfish, Gazebo Garden v7.5.0 and the latest PX4-Autopilot code downloaded today. I’m not using ROS in this setup, just Gazebo.

Hi  
I have the same problem. Have you solved it?

I realised that we need a Float\_V message to specify the colour gradient of the points in the point cloud for it to show up
