基于知识的地质剖面图生成器研究和实现

三维数据的获取一直是地质体可视化的难点，三维剖面建模技术通过二维的剖面图来描述地层等信息，将三维问题二维化，为三维数据获取提供了解决方案。但在利用计算机自动绘制剖面图的过程中，不但需要钻孔数据，还需要利用专家知识来绘制剖面图，因此提出将已有的专家手工绘制的剖面图作为一个重要的数据来源，生成虚拟钻孔数据，获取剖面生成知识。在此基础上，给出基于知识的剖面器开发方法，研究剖面图的数据模型和知识应用模型，并给出剖面图生成实例。

Research and Development of Knowledge-based Geology Section Chart System

Acquisition of 3D data is a nodus of geologic volume visualization.However,3D Section Modeling technology could simplify 3D problem to 2D problem by using section chart to represent the stratum information,which offers a solution to 3D data acquisition.In the process of automatically drawing section chart,the drill data and expert knowledge are necessary.The section chart drawn by hands whose format is grid is converted into vector format,then the section chart becomes a data source for virtual bore data and knowledge elicitation.On the basis of the theories above,the methodology of knowledge-based section drawer development is presented.Firstly,the data model and the knowledge application model are given;secondly,the concept of Virtual Bore (VB) is created;finally,the section chart example is described.
