Paper Abstract

In this paper a general geometric description of the optical methods for 3D coordinate measurement is presented. Similar to holographic interferometry this new approach is based on the concept of measuring sensitivity. As a special case the derived basic relation is applied to the fringe projection technique using a physical model of this measurement method. Moreover a geometric 3D model that contributes to a dramatic reduction of systematic distortions of measured 3D coordinates is presented. On the one hand this model is sufficiently general but on the other hand still easy to handle. It permits an explicit and direct determination of 3D coordinates from primary measuring data as well as a calibration of the measuring set-up using linear identification methods mainly. The described 3D model can be applied also with advantage to multiview registration tasks.
