Abstract
Dimensional measurement and deformation measurement is performed using a photogrammetric setup with 3 CCD-video cameras. Using the images of a parallel shifted reference cross grating the orientation of the cameras is determined fully automatically within some minutes on a PC. Then two software packages are available for the calculation of an arbitrary deformed cross grating and for deriving elements, e.g. circles, straight lines, cylinders, in space from their edges in the images. This can be done interactively or automatically after a teach-in process. Hence the method is well suited for production and quality control.
