Camera Calibration: Correct horizon (exceptional procedure)
Your Thermal’s camera has been factory-calibrated with unparalleled precision.
Unlike the calibration of Thermal 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 Thermal box on the FreeFlight 6 homepage (or
from the Thermal box of the HUD) and from the
“PREFERENCE – Camera”
menu.
Before starting this procedure, you need to position Thermal 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.
