For the description of the relation between the values of measurement and the coordinates in optical 3D-measurement systems different approaches exist. In principle, every method can be treated in the model of photogrammetry. For the coordinate determination the relevant parameters of this model must be known. Basing on the insights a concept of a new system will presented joining the advantages of fringe projection and photogrammetry. Its properties are a high number of points that can be measured, a quick analysis of the measurements combined with simultaneous determination of the system parameters and coordinates. First experimental results will be shown.
