对中杆倾斜检校的新方法探讨

摘要

现代测绘工作中全站仪正在被广泛使用,其配件棱镜对中杆以轻便实用等特点深受测绘工作者的喜爱,然而对中杆的倾斜与否将直接影响测量精度及测绘产品的质量。针对传统的对中杆检校方法繁琐不易操作的特点,本文提出了＂单方向十字交叉法＂和＂仪器脚架法＂这两种简单实用的检校新方法,并对它们的精度及应用领域进行了探讨。%Electronic Total Station is being widely used in modern surveying and mapping,centering rod is also loved by the majority of surveyors due to the light and practical characteristics,but its verticality or not will directly affect the survey accuracy and the quality of surveying and mapping products.For traditional calibration method is difficult to operate,the author puts forward two more simple and practical methods of centering rod calibration,analyzes and compares their accuracy and application.
