摘要
本文提出了一个多层DEM(Digital Elevation Model,DEM)及似三棱柱(Similar Tri-Prism,STP)混合的三维地层模型DEMs-STP,该模型使用多层DEM构建地表及地质分层界面,使用STP构造层间地质体,改进了STP的切割处理,并利用IDL作为开发工具,实现了三维可视化。实验结果表明,DEMs-STP混合数据模型具有同时表示空间对象表面和内部结构的能力,适合地质勘探领域的三维建模。
Proposed a 3D stratigraphic model DEMs -STP mixed Multi -DEM （Digital Elevation Model, DEM） with STP（Similar Tri- Prism）. The model uses Multi- DEM to build layered surface of the earthg sur- face and geology, and uses STP to makeup interlayer geological - mass, and uses IDL as the development tool, realizes 3D visualization. Finally the system applied in practical engineering to verify the accuracy and practical, and the result shows that the mixed data model DEMs - STP owns the ability of express spatial object surface and the internal structure simultaneously, and is suitable for 3 D modeling of geological exploration areas.
