ABSTRACT
Due to reflections and stray light it is often not possible to describe the dependencies between the projector-and camera-pixels by a bijective function. But the full problem is so extensive, that the relation between camera image I and projector pattern P has to be described as a N × M (where N is the number of image pixels and M is the number of projector pixels) matrix. This matrix TSurface, with more than 1012 values for modern measurement systems, describes the dependenciesbetween projector-and camera-pixel intensities. The external influences E depending on the external stray light and the camera noise should always be small for a good evaluation of the image series. For the camera image I is
I T P ESurface + .
