Abstract
A method of measuring surface sets on an object surface with a coordinate measurement device and a target scanner, includes providing the scanner having a body, a first retroreflector incorporating a pattern, a projector, a camera, and a processor, providing the device, selecting the source pattern of light; projecting the source pattern of light onto the object to produce the object pattern of light; imaging the object pattern of light onto the photosensitive array to obtain the image pattern of light; obtaining the pixel digital values for the image pattern of light; sending the first beam of light from the device to the first retroreflector; receiving the second beam of light from the first retroreflector; measuring the orientational and translational sets based at least in part on the second beam of light; determining the surface sets corresponding to the plurality of collinear pattern elements; and saving the surface sets.
