摘要
介绍了一种溯源于重力线的垂准仪校准方法;分析了"顶杆式铅垂准线"与"平行光管式水平准线"之间的联系与区别;基于顶杆式铅垂准线校准的几何模型,给出了天顶/底角的计算方法。
This paper introduces a new calibration method for plumb aligner.The difference between the new and traditional method is analized.Based on the proposed gemetrical model,the calculation of zenith/nadir angle and calibration table are presented.
