How can the m500 precisely land on an aruco marker.

[janis_blank]

Hello,

I'm not sure how precision landing is supposed to work.
Usually, I would have an aruco pattern drawn right on my landing pad. The drone now would have a downward facing camera that constantly monitors the pattern and sends corrective commands to the flight controller while slowly descending. All the m500 seems to have is three front facing cameras and a 45 degrees downward facing tracking sensor, but no camera on the bottom. How would precision landing be possible with this setup?
I'm currently thinking of mounting a USB camera to the bottom, connecting it to the Cellular LTE and USB hub add-on and doing precision landing with python, OpenCV and MavSDK commands, but is this really the best way?

Thanks and regards
