基于序列图像的土壤孔隙网络模型构建

在土壤序列数字图像基础上，利用3S图像分析技术进行预处理，结合形态学网络模型理论和孔隙拓扑结构，实现了孔隙网络模型的构建。模型确定了适合描述土壤孔隙空间拓扑特征的网络模型数据结构，研究了提高序列数字图像垂直方向分辨率的关键算法，以及切片水平和垂直方向上像元的连通判断问题。此模型是孔隙结构特征的直接映射，再现了孔隙三维结构。

Network Model Reconstruction of Soil Pore Based on the Serial Digital Images

By analyzing the soil sample with digital images of the soil slice and the technology of 3S,the pore network model was reconstracted based on the the theory of morphologic network model and pore topological characteristics.In the modeling course,the data structure of network model was established to describe the topological characteristics of soil pore space;the key arithmetic for heightening the vertical reselution,and the judgement of level and vertical connection were also studied.The model could truly d...
