Optical 3-d digitizing of object surfaces can be performed by combining fringe projection measurement systems and close-range photogrammetry. Photogrammetry provides fast and precise reference point determination to merge several point clouds generated by the range sensor. In this paper, 3-d measurements using a COMET digitizing system in combination with the DPA-Win photogrammetric software are reported on. Different digital cameras (consumer, prosumer, professional type) can be applied. Tests were carried out to determine the accuracy of the photogrammetric reference network with respect to the number of images and/or reference points.
