Abstract
A method of obtaining image data includes scanning an imaging area with an imaging device while obtaining multiple overlapping images of the imaging area. The method also includes transforming the overlapping images by performing frame averaging on the overlapping images to produce at least one enhanced image of the imaging area.
Claims5
A method of obtaining image data comprising:
- scanning an imaging area with an imaging device while obtaining multiple overlapping images of the imaging area;
- and
- transforming the overlapping images by performing frame averaging on the overlapping images to produce at least one enhanced image of the imaging area, wherein transforming the overlapping images includes identifying a region of interest, gathering images from the overlapping images that include the region of interest, performing compensation on the gathered images for optical distortion, compensating for orientation differences among the gathered images, selecting a master image, and registering the gathered images to the master image, wherein frame averaging is performed on the gathered images after they have been registered, wherein transforming the overlapping images by performing frame averaging is performed automatically at a coarse level to produce the at least one enhanced image, and further comprising:
- transforming the overlapping images by performing super resolution frame averaging on at least one portion of the at overlapping images to produce at least one super resolution image of the imaging area wherein the at least one super resolution image has a finer sampling than the at least one enhanced image.

A system for obtaining image data comprising:
- an imaging sensor optically coupled to optics for forming an image on the imaging sensor;
- the imaging sensor being mounted to a platform configured for scanning the imaging sensor over an imaging area while obtaining overlapping images of the imaging area;
- and
- a module operatively connected to the imaging sensor to receive the overlapping images and to transform the overlapping images by performing frame averaging on the overlapping images to produce at least one enhanced image of the imaging area, wherein the platform includes a stabilization mirror optically coupled to the imaging device, wherein the stabilization mirror is configured to counteract movement of the gimbal during each exposure while obtaining the overlapping images, wherein the module includes machine readable instructions configured to:
- transform the overlapping images by performing frame averaging automatically at a coarse level to produce the at least one enhanced image, and
- transform the overlapping images by performing super resolution frame averaging on at least one portion of the at overlapping images to produce at least one super resolution image of the imaging area wherein the at least one super resolution image has a finer sampling than the at least one enhanced image.
