Abstract:

The from Intergraph Z/I Imaging with 140 megapixels has been evaluated. This new camera is equipped with just one very large format CCD-array for the panchromatic band. The monolithic large format CCD does not require any stitching, enhancing the system accuracy. Test flights in three height levels with 5.7 cm up to 20.2 cm ground sampling distance (GSD) have been used for accuracy analysis of this camera. Very small systematic image errors confirm the excellent camera geometry. The root mean square differences at independent check points for the geometric critical height in the range of 0.7 GSD corresponds to the good image geometry.

Die Geometrische Eigenschaften der großformatigen Digitalkamera DMC II 140 von Intergraph Z/I Imaging mit 140 Megapixeln wurde untersucht. Diese neue Kamera ist für das panchromatische Bild mit nur einem sehr großen CCD-Sensor ausgestattet. Das homogene großformatige CCD erfordert keine Zusammenfassung von Teilbildern, was die Genauigkeit steigert. Bildflüge mit drei verschiedenen Flughöhen, entsprechend 5.7 cm bis 20.2 cm Objektpixelgröße, wurden für die Genauigkeitsanalyse der Kamera verwendet. Sehr kleine systematische Bildfehler bestätigen die ausgezeichnete Kamerageometrie. Die Quadratmittel der geometrisch kritischen Höhendifferenzen an unabhängigen Vergleichspunkten von 0,7 Objektpixeln entsprechen der guten Geometrische Bildqualität.

More about this publication?
  • Photogrammetrie - Fernerkundung - Geoinformation (PFG) is an international scholarly journal covering the progress and application of photogrammetric methods, remote sensing technology and the intricately connected field of geoinformation processing.

    Papers published in PFG highlight new developments and applications of these technologies in practice. The journal hence addresses both researchers and student of these disciplines at academic institutions and universities and the downstream users in both the private sector and public administration.

    PFG places special editorial emphasis on the communication of new methodologies in data acquisition, new approaches to optimized processing and interpretation of all types of data which were acquired by photogrammetric methods, remote sensing, image processing and the computer-aided interpretation of such data in general.

    PFG is the official journal of the German Society of Photogrammetry and Remote Sensing.
