The ZED cameras and the SDK are perfectly compatible with Ubuntu 20.04. You would be able to use the camera and the SDK without any issues with the OS.
Can I use the ZED on mobile, Raspberry Pi, or other platforms?
Is it possible to use the ZED cameras with tablets like the Surface Pro, iPad, and mobile devices, to get 3D mapping?
Can the ZED2 be powered over Ethernet (POE) or 12v powering options?
