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.
