Ground too feature rich? (Flow deck)

Post by ricardo.halfeld » Tue Jul 30, 2019 3:09 pm

Is there such a thing as a too feature rich ground for the flow deck? I've printed several ArUco markers (similar to QR codes) on an A4 paper and the CrazyFlie seems to have a hard time flying over it. I'm uploading a video, I'll post it soon.

Has anyone had similar issues?

Here's the video:

See how weird the horizontal position control behaves when it gets over the ArUco markers? It may have something to do with the altitude measurements, which are taken from the ceiling with the Multiranger Deck.

Hi!

Hmm it seems rather like an altitude problem to me. Have you tried to look at the optical flow measurements and height measurements?
