ABSTRACT

This paper deals with the topic of image calibration and transformation inside the
photogrammetric system FOTOM 2008. The calibration module is used for approximate
determination of outer camera parameters (position and rotation) with respect to
captured objects. An additional transformation is based on similarity of homocentric
circles and is accomplished in two steps, which will be described. Variables, obtained
from the calibration are used for corrective projection enabling easier measurement of
observed objects.
