一种代替测量观测墩的方法

Subsidence monitoring with Total Station, in order to achieve the building or ground settlement monitoring high-precision, the instrument high of total station is the main source of error of settlement, this general observation pier need to obtain the high-precision instrument high. However, due to limited engineering environmental conditions can not be established observation pier, and because to limited the measurement resource capacity and funding and must meet high precision deposition monitoring results, in this case, virtual observation pier technology came into being. This article will introduce the technology and methods of the theory.
