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。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 the6-DOF parameters in geographic coordinate are computed.This method can improve the diameter of measurement,and the sampling frequency.
