Abstract
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.
Claims28
A method for image stitching, comprising:
- determining a virtual line-of-sight (LOS) and a corresponding field-of-view (FOV) of an output mosaic;
- obtaining a plurality of input images, wherein each image of the plurality of input images contributes to at least one output mosaic pixel;
- and
- mapping contributions from the plurality of input images for each output mosaic pixel.

An apparatus for image stitching, comprising:
- a control processor for determining a virtual line-of-sight (LOS) and a corresponding field-of-view (FOV) of an output mosaic;
- a plurality of imaging sensors for generating a corresponding plurality of input images, wherein each image of the plurality of input images contributes to at least one output mosaic pixel of the output mosaic;
- and
- an image processor for mapping contributions from the plurality of input images for each output mosaic pixel.
