Abstract
Some special tools for car manufacturing and some parts for cars are requiring geometrical accuracies within few microns. Up to now the check for acceptance will be done by mechanical 3-D-measuring devices. This is very time consuming and expensive. Based on off-line tests with macro photographs and evaluation by close range photogrammetry, an on-line solution with CCD-cameras is under development. The necessary accuracy of some microns in the object space will be reached over distances up to 800 mm by orientation of the cameras in relation to a precise control field which is presented by a large reseau grid.
