基于先验信息的残余克里金法的研究

Prior Information Residual Kriging

论文在可视化插值过程中所遇到的精确数据点少,而先验信息比较丰富的情况下,以传统克里金插值法原理为基础,提出了基于先验信息的残余克里金插值法。该插值方法是一种精确的内插方法,在精确数据点密集的区域,插值的结果主要反映精确数据的变化,而在精确数据点少,先验数据多的区域,插值的结果反映的是先验数据的变化趋势。两个应用实例的结果验证了这一方法的特点。

Under circumstance,which there are a few accuracy data and a lot of prior information(data)in study area when interpolation during scientific visualization,this paper presents prior information residual kriging based on Linear kriging.The prior information residual kriging is accuracy interpolation method,it can reflect change of accuracy data in region where the accuracy data is dense,and it can also reflect trend of prior information in region where accuracy is mere,whereas the prior data is dense.Two examples are given to illustrate properties and characterizations of the Prior information residual kriging.
