Camera Calibration: Correct horizon (exceptional procedure)
Your ’s camera has been factory-calibrated with unparalleled precision.
Unlike the calibration of or that of the Parrot Skycontroller 3, which must be
carried out periodically, the camera calibration must not be carried out 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 box on the FreeFlight 6 homepage (or from the
box of the HUD) and from the “PREFERENCE – Camera” menu.
Before starting this procedure, you need to position 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.
