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