Abstract

A large format digital camera has a primary camera system configured for collecting panchromatic image data and a secondary camera system configured for collecting color image data. The secondary camera system has an optical system that has a longer focal length than the optical system of the primary camera system. The resolution of the secondary camera system is greater than the resolution of the primary camera system. The footprint of images produced by the primary camera system is larger in size than the footprint of images produced by the secondary camera system. Images produced by the primary camera system offer information for performing image-based georeferencing by means of photogrammetric triangulation. Images produced by the secondary camera system offer a high-resolution narrow angle color image suitable for use in ortho image production.

Description

Background technique [0001] Conventional methods and camera systems utilized for optical aerial registration (photogrammetric mapping) in urban areas typically suffer from several problems. For example, aviation regulations near urban airports often do not allow aircraft to fly at altitudes low enough to obtain acceptable image scales with conventional camera systems. As another example, images generated by traditional aerial camera systems often suffer from foreshortening, which makes buildings appear as if they are tilted. This is particularly problematic in urban areas, which often have many tall buildings. [0002] In view of the foregoing and other factors, the disclosure herein is presented. Contents of the invention [0003] Concepts and techniques for large format digital cameras with multiple optical systems and detector arrays are described herein. By implementing the concepts and techniques presented here, a large format digital camera with multiple optical sys...
