摘要
全站仪自由设站方法是高速铁路工程测量中的常用方法,通常采用仪器自带的程序进行设站。但是全站仪自带程序是基于半盘位进行自由设站,当仪器含有竖盘指标差时,设站的计算高程与实际高程就会存在较大差异。因此,为了解决现有技术中设站精度不高,以及自由设站对全站仪要求过高等问题,提出了一种基于全盘位测量的自由设站方法。
The free station setting method of total station is commonly used in high-speed railway engineering survey,usually using the built-in program of the instrument.However,the program is based on the half panel position.When the instrument contains index difference of vertical panel,there will be a big difference between the calculated elevation and the actual elevation.Therefore,this paper puts forward a free station setting method based on wholesale measurement,in order to solve the problem of low precision and high requirement for total station in the existing technology.
