Which 3D LiDARs PX4 supports, if any?

PX4 Autopilot
1

I did some research on which LiDARs PX4 supports natively. There doesn’t seem to be much on this matter with exception of a rangefinder LIDAR-Lite. Furthermore, this sensor is a single-point LiDAR rather than 3D one. From this I would conclude PX4 has very little to no support for 3D LiDARs with a 360° scan capability.

My use-case is involvement of a 3D LiDAR for advanced obstacle detection that would be a part of drone’s autonomous obstacle detection and avoidance.

If anyone has experience as such or knows if something as such is supported natively by PX4 itself, I would appreciate any information I can get.

Cheers!

There are no 3D Lidars supported.

This is usually done on a linux companion computer, with something like ROS2 which already has packages for various 3D lidars.

PX4 does support collision prevention, although recently I have seen reports that it is not working

Thanks for the info @dakejahl.

Any ideas which tools are commonly used to integrate 3D LIDAR (and possibly collision detection) within UAV in any context?

I’m not sure, you’ll have to do some research
