The Ultracam Large Format Aerial Digital Camera System

چکیده
The race is on to introduce an aerial digital camera system to outperform the current aerial film cameras in quality, accuracy and economics. We introduce the UltraCam-D large format digital aerial camera. It achieves superiority over conventional aerial film imaging. The system produces aerial "photography" as if a film camera had taken film images that then were scanned. As a result, images that get produced by the novel camera will feed into a current softcopy photogrammetry workflow without significant changes, yet with many advantages. These include quality advantages with superior radiometry and geometric stability resulting from the use of CCD technology. There are cost advantages due to the avoidance of film and scanning. Finally there are operational advantages due to instant quality control, image based navigational support reducing the need for imaging skills, and very short repeat intervals in the range of 0.75 seconds, optionally producing very high forward overlaps at no added cost. The technical specifications of the camera meet the requirement that it outperform a modern film camera system.

Development of Digital Aerial Cameras
Digital aerial cameras have replaced analogue aerial cameras in several countries. The development for operational aerial photogrammetry started with the line scan camera ADS40, followed by Z/I Imaging DMC and Vexcel Imaging UltraCam. Recently the line scan camera Jena Optronik JAS-150 was introduced. The capacity of the UltraCam was enlarged by replacing the used CCDs with 9μm pixels over 7.2μ...

Digital aerial cameras have replaced analog film cameras. An information contents corresponding to aerial photos up to 2010 was only possible with digital system cameras as Vexcel Ultracam and Z/I Imaging DMC or line scanning cameras as Leica Geosystems ADS80 or Jena Optronic JAS-150. Now with very large size CCDs the panchromatic band of the DMC II has between 140 and 256 Mega pixels from one ...
