US Patent 7499079 Multi-camera image stitching for a distributed aperture system

Distributed Aperture Systems use multiple staring sensors distributed around a vehicle to provide automatic detection of targets, and to provide an imaging capability at all aspects. The sensor image data is “stitched” to make the camera joints transparent to the operator. For example, images from three different cameras may be combined into a single seamless mosaic. The output mosaic is suitable for rendering on a head-steered helmet mounted display or a multifunction console display.
