数字化误差建模中的粗差探测和抗差估计

Gross Error Detection and Robust Estimation for Building Error Estimation Models of Digitizing

    摘要
  • 摘要: 介绍了用差分算子和时间序列分析法建立数字化过程随机误差估计模型中的粗差探测方法和抗差估计方案。

     

    Abstract: This paper presents two ways for establishing reliable stochastic error estimation models of digitizing cartographic curves against gross errors:(1) to form statistical testing models for detecting gross errors;(2) to robustify the error estimation models by employing robust estimation theory.
