摘要
主要研究设备安装与调试中动态测量数据处理的方法。考虑抗差估计和有偏估计理论的同时,在常规转换模型的基础上构造新的优化模型。实践证明,本方法不仅可以减弱外界条件引起坐标系变化误差的影响,还可以进一步减弱仪器误差,提高作业效率。
This paper mainly researches on the method of dynamic data preccessing in installing and debugging of equipments. A class of new modal is proposed on the basis of general modal, considering robust estimation and biased estimation. The practice shows that this method not only may decrease reference frame error caused outside condition but also weaken errors of theodolite and improve efficiency.
