ecom- mme- ping » icture (4), lution senta- Quality Features of a State-of-the-Art, High-Performance Photogrammetric Scanning System: PHODIS SC Gertrud Roth Carl Zeiss, D-73446 Oberkochen, Germany Commission I, WG I/5 Keywords: Scanner, photogrammetry, digital image, automatic, high resolution, high throughput ABSTRACT The system design of PHODIS SC meets the quality demands made on a state-of-the-art photogrammetric scanner. The hardware is charaterized by the capabilitiy of digitizing uncut original aerial films. Further features include high-precision mechanical guideways, optimum imaging performance of the mirror lens and superior resolution of the CCD line. The high data transfer rate ensures short scanning times. The system is rounded off by a software providing high operating convenience, image processing functions and basic photogrammetric functions. KURZFASSUNG Systemdesign von PHODIS SC erfüllt die Qualitátsanforderungen an einen modernen photogrammetrischen Scanner. Die Hardware ist gekennzeichnet von der Móglichkeit, unzerschnittene Originalluftbildfilme zu digitalisieren. Weitere Qualitátsmerkmale sind hochprüzise mechanische Führungen, optimale Abbildungseigenschaften des Spiegelobjektives sowie hohe Auflósung der CCD-Zeile. Die hohe Datenübertragungsrate garantiert kurze Scanzeiten. Einfache Scannerbedienung, Funktionen der Bildverarbeitung und photogrammetrische Grundfunktionen ergánzen softwaremäBig das Systemdesign 1 Introduction PHODIS SC features a modular structure (see Fig. 1) e the SCAI basic scanner unit, with control unit and Autowinder roll film attachment e the SC software e the AW software e and the PHODIS base software The increasing use of digital photogrammetry leads to a constantly growing demand for scanned aerial photos. Wheras until recently digitized aerial photos were primarily used for orthophoto production, the field of digital applications is now rapidly expanding. In addition to digital stereoplotting, the emphasis is placed today on digital aerotriangulation and matching techniques for DEM generation, to mention only two Fig. 1 examples. These latter applications, in particular, make extremely critical demands on the quality of the digital source PHODIS SC material, which can only be guaranteed by a high-precision photogrammetric scanner. PHODIS SC meets the new requirements made on a Scan unit Host photogrammetric scanner for the conversion of photos into Silicon Graphics digital images This includes the scanning of the original photos without any need to cut the film and without any intermediate : SC Software photographic processes for the generation of original digital Control unit SCSI-2| AW Software images, fully automatic digitization of the images and a high geometric and radiometric accuracy. Autowinder PHODIS SC has been fully integrated into the PHODIS photogrammetric image processing system from Carl Zeiss (see Table 1). It uses the same user interface, the same basic modules for image processing and photogrammetric tasks, the same data formats and the same computer platform as the other Ethernet members of the PHODIS family (Braun, 1996). The SCAI scanner unit comprises a high-precision measuring Table 1: PHODIS Product Family system with a powerful CCD line sensor for monochrome and : : color digitization, a control unit for controlling the scan cycles PHODIS Product Photogrammetric Application and the processing of the CCD data, and the Autowinder for PHODIS SC Photogr ammeine Scan System - the automatic digitization of complete uncut films. Data PHODIS AT Automatic Digital Aerotriangulation transfer to the computer is performed via a SCSI-2 interface. PHODIS ST Digital Stereoplotter The SC software includes all functions required for scanner PHODIS TS Automatic DEM Generation control, transfer and management of the image data, basic PHODIS OP Digital Ortho Projection photogrammetric functions and image manipulation functions. PHODIS M Monoplotting The AW software permits the control of the Autowinder and PHODIS Base Basic Digital Photogrammetry Tools direct operation from the computer. 163 International Archives of Photogrammetry and Remote Sensing.
