Aircraft panoramic display
First Claim
1. A display system for use in an aircraft, the display system being adapted to receive signals representing the orientation of the aircraft and to produce a corresponding display, the display system comprising:
- a nonspherical display screen; and
line generation means for generating a line image on the nonspherical display screen such that the position of the line image on the display screen corresponds to the position of a projection of a three-dimensional artifact external to the aircraft onto an imaginary window to an eye point within the aircraft, the eye point being positioned on the opposite side of the window from the artifact, wherein the line generation means includes means for determining the position of a great circle on a sphere having its center at the eye point such that the position of the great circle on the sphere corresponds to the artifact projected onto the sphere to the eye point, and means for generating the line image on the display screen such that the position of the line image on the nonspherical display screen corresponds to the position of the great circle on the sphere.

Abstract
A panoramic display system for an aircraft comprising a display screen and line generation means for generating a line image on the display screen. The position of the line image on the display screen corresponds to the position of a projection of an artifact external to the aircraft onto an imaginary window to an eye point within the aircraft. The eye point is positioned on the opposite side of the window from the artifact. The line image may be generated by determining the position of a great circle on a sphere having its center at the eye point, such that the position of the great circle corresponds to the artifact projected onto the sphere to the eye point. The position of the line image on the display screen corresponds to the position of the great circle on the sphere. The display system may comprise a plurality of display screens positioned adjacent to one another such that each can be viewed from a single viewing point. Partial line images are generated on each display screen such that the position of each partial line image corresponds to the position of the projection of the artifact onto a window portion to the eye point. The eye point is common to all window portions, and the spatial relationship of the window portions with respect to one another is congruent with the spatial relationship of the display screens with respect to one another.
