Patent number: 10459224Abstract: A system and method of displaying a conformal-capable head-up display image is provided. Distortions caused by combiner curvature, for example, are removed by pre-distorting and projecting separate images for each eye. Shutter-based eyewear controls the visibility as the imagery is cycled, e.g., shuttered, between left and right eyes. The combined image generator, projector and eyewear system maintains minimal vergence errors, minimal dipvergence errors, acceptable average transmittance, and optionally, high conformality.Type: GrantFiled: September 29, 2014Date of Patent: October 29, 2019Assignee: HONEYWELL INTERNATIONAL INC.Inventors: Brent D.
