全站仪测量的精度影响因素分析

Analysis of influencing factors on the accuracy of total station measurement

全站仪在野外开展测量工作时,由于外界环境、观测者的个人能力和仪器本身等诸多客观因素综合导致测量误差的产生,影响测量的精度。分析探讨全站仪在实际测量工作中的测量方式、仪器本身、反射介质、外界因素、观测者等因素对测点的影响,并提出了一些避免误差的建议,这些对测量人员的工作效率和测量的精度有着非常大的帮助。在实际生产中避免这些因素影响带来的误差,对全站仪测点精度是非常必要的。

When the total station is in the field,many objective factors,such as the external environment,the observer’s personal ability and the instrument itself,lead to measurement errors and affect the accuracy of measurement.This paper analyses and probes into the influence of the measuring mode,instrument itself,reflection medium,external factors and observers of total station on the measuring points in the actual measuring work,and put forward some suggestions to avoid errors,which are of great help to the working efficiency and measuring accuracy of the surveyors.To avoid the errors caused by these factors in actual production,it is very necessary to measure the accuracy of the total station.
