摘要： 使用三个转换点与已知北向方位的经纬仪，将激光跟踪仪的测量坐标系转换到经纬仪原点的当地地理坐标系。在被测物体上固定三个测量点，构建一个被测轴系，使用三台建立当地地理坐标系的激光跟踪仪，对应上述三个测量点进行点位测量，即可解算出被测轴系在当地地理坐标系下的六自由度参数。采用该方法进行测量可以增加六自由度测量半径与采样频率。

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
