Abstract
Measuring with a system having retroreflector targets and a laser tracker includes storing a list of nominal coordinates for targets and one added point; capturing on a tracker photosensitive array a portion of the light emitted by a light beam and reflected off the targets; obtaining spot positions on a tracker camera photosensitive array from light reflected off the targets; determining a correspondence between three spot positions on the tracker photosensitive array and the nominal coordinates of the targets; directing a beam of light from the tracker to the targets based on the nominal coordinates of the first target and the first spot position; measuring 3-D coordinates of the targets with the tracker; determining 3-D coordinates of the at least one added point based on the measured 3-D coordinates of the targets and the nominal coordinates of the one added point.
