“2×2段法”检测仪器加常数的研究

Research in "Double Two-range Method" for Testing Distance Meter's Additive Constant

测绘作业中测距仪或全站仪需定期进行检验,以保证仪器处于正常的运行状态,测距仪的仪器加常数C的检测是重要的检测项目之一。由于各种因素的影响,C值会发生变化,因此需要经常检测。目前C值的检测方法比较复杂,为适应实际需要,研究了C值检测的"2×2段法"。实践证明,利用该方法可以方便、快捷、准确、无需已知基线的场地、随时自行检测。

It is need testing periodical that total station applies to surveying and mapping. That the additive constant of total station distance measuring system is important one of testing items. Because of influence of factors, the constant could occur to change, thus it is need to frequently test. C value testing method is more complex at the present time, for practice need, this paper discusses ＂double two-range method for testing distancemeter＂, for C value could testing with it. It is conveniently, fast, precise, need not standardized site length, at any time oneself.
