| 摘 要： | 现行的光电测距仪检定规程JJG 703-2003所规定的比较法要求野外测量工作量较大。在保证检定结果精度提高的前提下,说明了全站仪与因瓦尺比对法及简单解析法两种测定加常数的操作方法和计算公式,提出了使用加常数修正野外基线测量距离后单独计算测距乘常数的思想,分析了各种方法的测量精度,利用多台全站仪的实测数据进行了计算。结果说明,加乘常数分离检定法与目前普遍实行的联合检定法比较,具有可靠性更好、精度相当、外业工作量少50%等特点。

| Abstract: | The invar scale contrast method and the simple analytical method were conventional technique for verifying ranging additive constant.The computation formula and operation were introduced for these methods.A novel method was proposed which is independent calculated ranging multiplication constant after the measured distance was corrected using additive constant.Verifying data of many total station instruments were calculated.The results indicated that the new method is more reliable,less workload and consist... |
