摘要
本文研究并公开了一种全站仪作业模式下,基于惯性导航轨道几何状态测量仪的单点测量设站方法,着重从原理进行叙述,并对该方法的正确性进行算例验证。该方法与多点测量设站相比,效率提升了一倍,且节省了人力,横向精度相当,竖向精度略低于多点测量设站,精度可满足有砟铁路轨道铺设粗捣时期轨道线形测量。
This paper studies and discloses a method of single point measurement station for INS track detector under total station mode,the principle is described in detail,and the method is verified by an example.Compared with multi-point measurement station method,the efficiency of this method is doubled,the lateral accuracy is equivalent,and the vertical accuracy is slightly lower than that of multi-point measurement station method.The accuracy of our new method can meet the requirements of track alignment in coarse tamping period of ballasted railway track laying.
