Einsatz digitaler Kameras im Auflösungsbereich von 5 cm bis 1 m - Die neue HRSC-AX Kamerageneration in der geometrischen Analyse

Abstract

Since 1997 the High Resolution Stereo Camera - Airborne (HRSC-A) is operated as the first digital stereo-photogrammetric camera. In spring 2000 the HRSC-AX, a derivative of the HRSC-A, started operation, it is the wide-angle version (47 mm) of the new HRSC camera generation using 12k CCD line techology. Now, since spring 2001, the HRSC-AX (150 mm) has been completed and was tested extensively. The HRSC-AX ist the successor of the narrow-angle HRSC-A. but also extended by 12k technology and other features in order to further improve the quality of the orthoimage- and 3D-products. This paper describes the geometric tests related to the new HRSC-AX camera generation. It will show the efficiency of the system, consisting of camera hard- and software, geometric calibration, direct DGPS/INS georeferencing, and automated photogrammetric processing software. Image resolutions and accuracies down to the sub-decimeter range will be exposed by numerical results of test flights and image examples.
