Abstract
A method for determining when a laser tracker is stable includes performing a plurality of first frontsight measurements and a plurality of first backsight measurements on a first target with the laser tracker, wherein the plurality of first frontsight measurements and the plurality of first backsight measurements are alternated in time, calculating a plurality of first two-face errors based on the plurality of first frontsight measurements and the plurality of first backsight measurements, determining at least one first stability metric based at least in part on the plurality of first two-face errors, the at least one first stability metric being a value defined by a rule, determining whether the laser tracker is stable based at least in part on the at least one first stability metric and a first termination criterion and generating an indication whether the laser tracker is stable or not stable.
