Ar200 Calibration (Linearization) - Raymarine AR200 Installation Instructions Manual

• To Calibrate the camera's Horizon position use the arrow keys to align the horizontal red line so
it is level with the horizon.
• Pan and tilt the camera 360° during calibration to ensure the horizon line has been positioned
correctly.
Important:
Calibrating the horizon correctly is essential for accurate Augmented Reality overlay. Calibrating
on calm water and in clear sight of the horizon is recommended.

9.2 AR200 Calibration (Linearization)

To enable accurate placement of Augmented Reality (AR) flags on the camera's video feed, the
AR200's AHRS sensors need to compensate for local magnetic fields, as well as the Earth's magnetic
fields.
Calibration is achieved using an automatic linearization process. The linearization process starts
automatically after your vessel has turned approximately 100°, when travelling at a speed of between
3 to 15 knots. The linearization process requires no user input, however at least a 270° turn is
required before linearization can be completed. The duration of the linearization process can be
decreased by completing a full 360° turn, when travelling at a speed of between 3 to 15 knots. The
linearization process can also be restarted at anytime.
Important:
• Calibrating the cameras forward position is essential for accurate
Augmented Reality overlay when the camera pans and tilts. Calibrating
on calm water and with a clear view of the front of your vessel is
recommended.
• Certain cameras display a camera direction indicator which can help
identify when the camera is facing directly forward.
