Design and Realization for Network Model Reconstruction of Soil Pore

本文利用土壤孔隙序列数字图像数据,结合形态学网络模型理论和孔隙拓扑结构,经过对孔隙网络模型的程序设计,实现了土壤孔隙网络模型的构建。该设计确定了适合描述孔隙空间拓扑特征的网络模型数据结构,运用插值算法提高了序列数字图像垂直方向的分辨率,运用邻近像元聚类法,以及表面绘制法解决了孔隙三维空间的连通判断问题。所得模型再现了孔隙三维结构,是孔隙结构特征的直接映射,界面友好,能够定量获取孔隙结构的三维重要特征参数。

The network model of soil pore was established by the program of pore network module which based on the application of the digital images of the soil slice, the theory of morphologic network model and pore topological characteristics. In the design course, it established data structure of network model to describe soil pore space topological characteristics, used the interpolation arithmetic to heightening the vertical resolve, and the method of superficial rendering to solve the problems of level and vertical connection. The model with a friendly interface dialogue could truly describe space distribution and gain topological characteristics of pore in soil.
