Abstract:

The geometric performance of digital airborne cameras also including the impact of direct sensor orientation has been evaluated by a test of the German Society of Photogrammetry, Remote Sensing and Geoinformation (DGPF). This test includes following airborne photogrammetric cameras: the large format frame cameras Z/I Imaging DMC, Vexcel Imaging UltraCamX and the line scanning camera system Leica Geosystems ADS40 (2 generation) and Jena Optronik JAS-150 as well as the mid-format camera Rolleimetric AIC-x1 and the combination of four mid-format cameras Quattro-DigiCAM. The results presented in this paper were achieved by a group of researchers from different institutions, working independently from each other and with different programs for data acquisition and bundle block adjustment. Moreover, different adjustment configurations (i.e. with/without use of perspective centre coordinates and/or attitude information from GPS/inertial systems), and also different control point configurations have been used in the test; this results in a wide range of solutions and accuracy results which are not easy to compare, on the other hand this just shows the spectrum of possible solutions in operational applications.

Das geometrische Potential digitaler Luftbildkameras, auch unter Berücksichtigung der direkten Sensororientierung, wurde im Rahmen eines Tests der Deutschen Gesellschaft für Photogrammetrie, Fernerkundung und Geoinformation (DGPF) untersucht. Dieser Test schließt folgende Kameras ein: die großformatigen Kameras Z/I Imaging DMC, Vexcel Imaging UltraCamX und Zeilenkameras Leica Geosystems ADS40 (2. Generation) und Jena Optronik JAS-150, sowie die Mittelformatkamera Rolleimetric AIC-x1 und die Kombination von vier Mittelformatkameras Quattro-DigiCAM. Die in diesem Bericht präsentierten Ergebnisse wurden von einer Gruppe wissenschaftlicher Mitarbeiter verschiedener Universitäten mit unterschiedlichen Datenerfassungsprogrammen, unterschiedlichen Bündelblockausgleichungsprogrammen, unterschiedlichen Konfigurationen der Ausgleichungen (z. B. mit/ohne Verwendung von Projektionszentrumskoordinaten und Richtungsinformation aus GPS/inertial Systemen) und unterschiedlicher Passpunktkonfiguration erzeugt. Diese Ergebnisse geben einen Überblick über die Variation der Lösungen und Genauigkeiten, die auch in operationeller Anwendung gegeben ist.

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.
