Claim 9:
10. A method of scanning a scan area with a three-dimensional (3D) measuring device comprising:
rotating the 3D scanner about a first axis, the 3D scanner having a light source, a light receiver and a photogrammetry camera;
emitting a plurality of light beams from the light source and receiving with the light receiver a plurality of reflected light beams from an object surface within the scan area;
determining, with a processor system, 3D coordinates of a first collection of points on the object surface within a scan area based at least in part on the plurality of light beams and the plurality of reflected light beams;
identifying transition locations where adjacent segments on a single scan line transition from a first color to a second color;
recording locations of the transition locations as first to second color transition locations;
identifying and recording transition locations where adjacent segments on a single scan line transition from the second color to the first color as second to first color transition locations;
forming a transition line through adjacent first to second color transition locations and adjacent second to first color transition locations; and
identifying a location of a checkerboard target based on the transition line.
