如何消除雾霾天气对全站仪野外检定的影响

How to Eliminate the Influence of Fog and Haze of Total Station Instrument Field Test

在全站仪野外检定过程中通常采用光照准模式,该模式对较远距离点测量时需要较好的气象条件的配合。近年来,我国秋冬季节普发的雾霾天气使得仪器野外测量时无法精确照准目标,使检定工作不能顺利完成。本文主要探讨了应用智能全站仪的ATR照准模式进行全站仪野外检定的可行性,通过选用不同型号的全站仪用光照准模式及ATR照准模式进行野外检定,并对实验数据进行统计分析,得出了采用ATR照准模式进行野外检定可消除雾霾天气的不利影响,得到准确可靠地检定数据的实验结论 。

The optical sighting mode is often used in the process of the total station field verification, the mode of coordination of mete- orological condition better than the distant point measurement. In recent years, Chinas autumn and winter haze weather makes the in- strument field measurement is not precise aiming the target, so that the verification work can not be completed successfully. This paper mainly discusses the feasibility of field verification using intelligent total station ATR sighting mode, field verification by total station optical sighting use different types of ATR and sighting mode, and by analyzing the experimental data, ATR model is obtained a field calibration can eliminate the adverse effects of the haze weather, get accurate experiment conclusion reliable testing data.
