摘要
对几种三维空间数据模型进行了比较,总结了克里格(Kriging)插值方法在三维地质体建模方面的种种优点。在此基础上,借助于GSTL开源地质统计学库和wxWidgets界面库,在Dev-cpp开发环境下开发了一个三维矿体数据的克里格插值系统,为矿体的三维可视化提供了数据支持。该系统实现了Kriging插值、变异函数拟合模型拟合程度的验证—交叉验证以及特定格式的结果输出等功能。
Comparing several 3D spatial data models, various advantages of Kriging interpolation algorithm in 3D geological body modeling are summed up. On this basis, by means of open source geostatistics template library GSTL and interface library wxWidgets, a Kriging interpolation system of 3D orebody data is developed in Dev-cpp environment, which provides data support for orebody 3D visualization. This system has realized the functions such as Kriging interpolation, the fitting degree validation of variogram fitting model--cross validation, and the results output in specific format.
