Abstract

Abstract: A new method is expounded which transforming the measuring coordinate to local geographic coordinate，by using three transfer-points and a theodolite known azimuth. Three laser trackers built the geographic coordinate, severally measure three points on the aim object which can create a aim coordinate, and then the 6-DOF parameters in geographic coordinate are computed. This method can improve the diameter of measurement, and the sampling frequency.

Key words: Laser tracking, Geographic coordinate system, 6-DOF measurement, Metrology
