More Information
Summary:A device and method for presentation of bezel embedded head tracking fiducials within an aircraft cockpit incorporates two and three-dimensional fiducial markers within a bezel of a forward display. Oriented in a constellation within a constant field of view of the pilot, the fiducials are specifically configured for continuous recognition by an optical sensor associated with a head worn display (HWD). With continuous constellation recognition, the HWD identifies the bezel embedded fiducials and determines a high integrity pose solution of a head reference frame relative to the aircraft enabling the system to present a high integrity primary flight display to the pilot without requiring an additional flight display available. Using active backlit short-wave infrared (SWIR) lighting and/or passively coated with reflective material specifically tuned to the night vision systems available to the HWD sensor, the bezel embedded fiducials allow operation of the HWD systems in any illumination environment.
