中文摘要:
      因工程测量中的测量数据经常存在粗差,对后续计算造成很严重的影响,故本文讨论数据探测法在水准网平差、曲线拟合等计算中的应用。首先介绍数据探测法的原理和计算步骤,然后阐述几种测量数据处理的方法,最后利用实际数据进行验证。实验结果表明,该方法能有效地发现并剔除粗差,可广泛应用于工程测量的数据处理中。
英文摘要:
      Gross errors of measurement data often exist in engineering survey, which resulting in a very serious impact on the subsequent calculation. This paper discussed the application of data snooping in level network adjustment and curve fitting. Firstly, introduces the principles and calculation steps of data snooping. Secondly, describes several methods of measurement data processing. Finally, demonstrates the validity with actual data. The experimental results show that this method can find out and eliminate the gross errors effectively, and could be widely used in data processing engineering survey.
