利用Delaunay三角网插值煤层零点线的方法研究

Interpolation of Coal Seam Zero Line Using Delaunay Triangulation

煤层零点线在煤田地质三维建模、编制煤层底板等高线图、等厚线图时都承担着很重要的角色。根据Delaunay三角网的两个特性及与人工产生零点线方法的差异,介绍了基于Delaunay三角形面积求零点的方法。本方法能有效克服手工确定零点连线方法产生的易出错及丢线难题,方法简单实用,易于操作,在计算机制图时可自动生成结果,快速准确。

The coal seam zero line plays an important role in coal geological 3D modeling and coal seam floor contour and isopach maps compilation.The paper introduced two characters of the Delaunay triangular mesh and what is the method differ from manual zero line generation,then proceed to Delaunay triangle area zero point seeking.The method can get over manual zero line generation puzzles of easy to make mistakes and line loss,also the method is simple to use,easy to operate and can automatically generate results in computer mapping,quick and correct.
