This book was conceived during the Workshop „Calibration and Orientation of Cameras in Computer Vision“ at the XVIIth Congress of the ISPRS (In ternational Society of Photogrammetry and Remote Sensing), in July 1992 in Washington, D. C. The goal of this workshop was to bring photogrammetry and computer vision experts together in order to exchange ideas, concepts and approaches in camera calibration and orientation. These topics have been addressed in photogrammetry research for a long time, starting in the sec ond half of the 19th century. Over the years standard procedures have been developed and implemented, in particular for metric cameras, such that in the photogrammetric community such issues were considered as solved prob lems. With the increased use of non-metric cameras (in photogrammetry they are revealingly called „amateur“ cameras), especially CCD cameras, and the exciting possibilities of acquiring long image sequences quite effortlessly and processing image data automatically, online and even in real-time, the need to take a new and fresh look at various calibration and orientation issues became obvious. Here most activities emerged through the computer vision commu nity, which was somewhat unaware as to what had already been achieved in photogrammetry. On the other hand, photogrammetrists seemed to ignore the new and interesting studies, in particular on the problems of orienta tion, that were being performed by computer vision experts.

This collection explores advancements in 3D surface matching, sensor modeling, and automated image processing techniques. It discusses a new algorithm for 3D surface matching and presents an advanced sensor model tailored for panoramic cameras. The performance of the A TOMI system in automated road extraction and updating is compared using various orthoimagery sources, including aerial film and satellite imagery from ADS40, Ikonos, and Quickbird. The potential of Ikonos and Quickbird imagery for accurate 3D point positioning, orthoimage, and DSM generation is also examined. The work includes 3D modeling and visualization of significant cultural heritage sites, alongside image analysis for historical cartography. Surface discontinuity modeling through patch adaptation and edge utilization is addressed, along with experiences in automatic image matching for DSM generation with ADS40 data. The orientation of satellite and airborne imagery using multi-line pushbroom sensors is discussed, as well as automated DSM generation from SPOT-5/HRS stereo images. Additional topics include character reconstruction from monocular image sequences, cloud modeling and visualization, and the accuracy of automated aerotriangulation for low textured imagery. The extraction and classification of wetland features in Botswana through remote sensing image fusion is highlighted, alongside the introduction of a new airborne three-line scanner for large-s

The annotation discusses various advancements in human body modeling, topographic object reconstruction, and glacier monitoring through innovative techniques. D' Apuzzo et al. introduce a least squares matching tracking algorithm for human body modeling. Eidenbenz and Käser focus on ATOMI, an automated method for reconstructing topographic objects from aerial images using vectorized map information. Favey and colleagues explore surface modeling for alpine glacier monitoring via airborne laser scanning and digital photogrammetry. Grün presents automated approaches for site recording and modeling, while also detailing 3-D recording and visualization of the Nasca geoglyphs. Honikel discusses Wiener-based interferometric signature reconstruction, and Niederöst emphasizes reliable building reconstruction for digital map revision. Park and Zimmermann investigate color image matching for DTM generation and house extraction, while Poli and Seiz examine cloud-top height estimation from satellite stereopairs for weather forecasting. Seiz and Baltsavias also delve into cloud mapping using ground-based imagers. Wang and Gruen propose a hybrid GIS for 3-D city models, and Willneff and Maas detail the design of a four-headed camera system for microgravity research. Zah et al. apply photogrammetry in freshwater ecology, analyzing high alpine flood-plain morphology, and Zhang and Baltsavias focus on knowledge-based image analysis for 3D edge
