PROBLEM TO BE SOLVED: To provide an automatic measurement method for dimensional data with a laser tracker, which enables the dimensional data to be more easily measured.SOLUTION: Measuring with a system having retroreflector targets 26 and a laser tracker 10 includes: storing a list of nominal coordinates for three targets and one or more added points; capturing on a photosensitive array of a camera provided in the tracker a portion reflected by the three targets, of light emitted from a light source; measuring spot positions on the photosensitive array; identifying a correspondence relation between three spot positions on the photosensitive array and the nominal coordinates of the three targets; directing a beam of light emitted from the tracker to the three targets based at least in part on the spot positions and the target nominal coordinates; measuring three-dimensional coordinates of the three targets with the tracker; and obtaining three-dimensional coordinates of the added points based at least in part on the three-dimensional coordinate measurement results of the three targets and the nominal coordinates of the one or more added points. |
