Claim 0:
1. A three-dimensional (3D) measuring device comprising:
a processor system including a processor;
a housing;
a 3D scanner disposed within the housing and operably coupled to the processor system, the 3D scanner having a light source, a beam steering unit, a first angle measuring device, a second angle measuring device, and a light receiver, the beam steering unit cooperating with the light source and light receiver to define a scan area, the light source and the light receiver configured to cooperate with the processor system to determine locations a plurality of points in the scan area;
wherein the processor is configured to identify locations of one more checkerboard targets disposed in the scan area by:
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.
