Hello guys. Im new here and also new in this drone world.
I have PIXSURVEY Cube V3 and skydroid H16 system.
Can they be used for real time QR code detection by using the skydroid H6 live camera feed?

I don’t know what this PIXSURVEY Cube V3 is, and whether PX4 runs on it. The label on it says ArduPilot, so maybe ask the question over in discuss.ardupilot.org.

Regarding real time QR code detection: I suppose you can do the detection on the ground using the video feed, assuming the video feed works. But I assume that’s all up to you and how you integrate all the pieces.
