DJI
Am I correct in thinking that the ground sensor array on the underside of the Inspire.
Will have difficulty keeping position above smooth featureless floor?
And under those circumstances.
Would placing a mark on the floor for the machine to track cure or improve the accuracy?
Providing that the mark is within the scan area of the ground facing camera?

PS
Apologies for incorrect banner on my previous post.
Regarding Galaxy Tab 4.
Afflicted by brain fade obviously.

It is ok, but not recommended move the mark.
