【摘要】：通过对地质体的三维可视化模拟,能够对地质体内部的地质构造和结构进行直观、准确、全面地表达,为地质体的研究提供了数字化工具,开辟了三维GIS研究的新视点,同时三维地质体勘查建模的程序设计对促进数字化矿山的发展也有一定的借鉴意义。本文是以国家地理信息测绘局重点实验室开发基金项目《基于IDL和Skyline的三维矿山建模方法研究》为支撑,以三维地质体勘查建模方法为核心,自主研究并实现了关于地质体建模的程序设计,取得的成果如下:(1)对三维地质体勘查建模方法进行了研究,基于交互式数据语言IDL,利用钻孔数据,实现了钻孔柱状图的显示;利用IDL对象模型,实现了三维地质体表面模型及实体模型的建模和集成显示;同时设计了具有友好的人机交互的界面,用于地质体三维建模和可视化的研究,而且可以对生成的地质模型进行平移、旋转、缩放等交互式操作,实现剖切显示,信息获取、纹理贴图等功能,从而能够有效地对未知地质信息进行分析。(2)以孙家墩矿段的建模为实例,进行了程序设计的测试工作,验证了本设计具有一定的实用价值。
[Abstract]:Through the three-dimensional visualization simulation of geological body, the geological structure and structure of geological body can be visualized, accurately and comprehensively expressed, which provides a digital tool for the study of geological body and opens up a new viewpoint of three-dimensional GIS research. At the same time, the program design of 3D geological body exploration and modeling also has certain reference significance to promote the development of digital mine. This paper is based on the National Geographic Information Mapping Bureau key Laboratory Development Fund project "Research on 3D Mine Modeling method based on IDL and Skyline", with 3D geological body exploration and modeling method as the core. The program design of geological body modeling is studied and realized independently. The results are as follows: (1) the modeling method of 3D geological body exploration is studied, and the borehole data is used based on interactive data language IDL,. The display of borehole histogram is realized. The modeling and integrated display of 3D geological surface model and solid model are realized by using IDL object model. At the same time, the interface with friendly man-machine interaction is designed, which can be used in the research of 3D modeling and visualization of geological bodies, and can be used to translate, rotate, zoom and other interactive operations to realize the cutting display and information acquisition. Texture mapping and other functions can effectively analyze the unknown geological information. (2) taking the modeling of Sunjiadun mine section as an example, the testing work of program design is carried out, which verifies that the design has certain practical value.
