Camera Calibration: Correct horizon (exceptional procedure)
Note: Your
ANAFI USA
’s camera has been factory -calibrated with high precision.
Unlike the calibration of
ANAFI USA
or that of the Parrot Skycontroller USA , which
must be performed periodically, the camera calibration must not be performed unless
it appears necessary, typically, after a crash. If you notice a tilted horizon on all your
videos and photos, and if this tilt is always on the same side, access camera
calibration to make your horizon perfectly straight again.
This feature is accessible from the
ANAFI USA
box on the FreeFlight 6 homepage (or
from the
ANAFI USA
box of the HUD) and from the
“PREFERENCE – Camera”
menu.
Before starting this procedure, you must position
ANAFI USA
on a flat and perfectly
level surface, exactly perpendicular to any pattern containing straight lines you can
use as horizon references. A set square can help you check that a line on your floor is
perpendicular to your wall, as on the following pictures.

When
ANAFI USA
is correctly positioned, perpendicular to its straight horizon
reference, power it on, along with the Parrot Skycontroller USA .
