Abstract
A system and method for automatically aligning immersive displays, including helmet-mounted displays, such displays creating composite images from at least one image source. A gimbal-mounted camera/rangefinder apparatus is used to create a high resolution three-dimensional (3D) map of the screen surface which, in turn, is used to generate geometric corrections of projected image segments. The rangefinder is typically a laser rangefinder and the laser element thereof can draw display channel outlines of the screen. The gimbal-mounted camera/rangefinder is used to automatically analyze a test pattern projected onto the screen, typically without geometric correction. Each defined point of the test pattern may then be 'moved' to its proper location on the 3D screen map. Video signal processing, performed either in software or hardware, accomplishes geometric correction, edge blending, color (e.g., gamma) correction and intensity matching. Unique polygonal blend regions are used for edge blending.
