侵入型岩体三维可视化构模技术研究

Technique of 3D visual modeling on intrusive rock-mass

根据侵入型岩体的空间几何特征及地质数据的特点 ,采用断面构模技术实现侵入型岩体三维构模。利用多条轮廓线之间的三维表面重构方法 ,构建侵入型岩体的表面模型。在生成体数据时使用改进的MC法 ,提高了构模精度 ,将多条轮廓线之间的表面重构问题转化为体数据中的等值面构造问题。开发了一种三维可视化构模系统 ,并利用该系统所提供的构模技术 ,实现了灵宝金矿侵入型岩体三维模型的构建。

According to the characteristics of geometric shape and geology data of intrusive rock-mass, 3D modeling method is established. The section method is adopted to model intrusive rock-mass. 3D reconstruct of a set of planar contours is used to create the surface model of intrusive rock-mass. The problem of reconstruct of a set of planar contours is translated into the problem of structuring equivalent surface of body data. Visual modeling system based on the modeling technique is developed, being used to model the intrusive rock-mass in Lingbao mine.
