Stereo camera calibration in progress
• Be aware that FreeFlight 7 can prompt you to carry out this calibration when needed. It is not mandatory
to take off, but it is recommended.
Horizon calibration (exceptional procedure)
Your ANAFI Ai’s camera has been factory-calibrated with unparalleled precision.
Unlike the magnetometer calibration of ANAFI Ai or that of the Parrot Skycontroller 4, which must be carried
out periodically, the horizon 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
horizon calibration to make your horizon perfectly straight again.
This feature is accessible from the ANAFI Ai page on the FreeFlight 7 dashboard (or from the ANAFI Ai box of
the HUD).
Before starting this procedure, you need to position ANAFI Ai on a flat and perfectly level surface, exactly
perpendicular to any pattern containing straight lines you can use as horizon references.
A half empty large water bottle provides a useful horizon line almost anywhere.
When ANAFI Ai is correctly positioned, perpendicular to a horizon, power it on, along with the Parrot
Skycontroller 4 and your device, as you would for any flight.
Access the calibration menu from the ANAFI Ai page of the dashboard of FreeFlight 7.
Select the “Horizon calibration” option.
Tap “–“ or “+” until the artificial horizon of ANAFI Ai matches the horizon reference facing the drone.
When you have straightened the tilt of the camera, tap the “<” icon on the top left of the screen to
confirm your setting and exit horizon calibration.
