| 摘 要： | 目前,全站仪广泛应用于工程测量,而在实际工作中,会出现全站仪测量无法实现对中整平或者对中整平后无法实施测量的情况。针对这种特殊情况,提出了一种全站仪测量的新思路,通过采用任意旋转角坐标转化的方法,可以将不对中不整平条件下全站仪测量的三维坐标观测值转换到已知坐标系中,并通过实验数据验证转换的精度。实践证明,该方法在实际应用中是可行的。

| Abstract: | Currently,the total station has been widely used in engineering surveying.But sometimes during the surveying by total station,it is the centering and leveling that can't be achieved,or the measurement can't be implemented after total station centered and leveled.As a special case,a new idea of total station measurement was proposed.It could convert the 3D observations,measured by the non-centered and non-leveled total station,to the known coordinate system,with the method of arbitrary angle rotation coordinate transformation.In addition,precision of the transformation was validated through the experimental data,which had proved that the method was feasible in the practical application. |
