基于剖面的层状与非层状矿体的三维可视化研究

Section-Based 3D Visualization Modeling of Stratified and Non-Stratified Orebodies

二维轮廓线重构三维表面是矿体几何建模的重要技术手段。对几种重构中可能出现的问题(轮廓对应问题和轮廓拼接),提出了适合地质体剖面建模使用的轮廓线重构算法。基于剖面的三维地质建模流程,建立地质体的线框面模型及其相应的地质块体模型。

Reconstruction of 3D sections by 2D contour lines is an important technical means in geometric modeling of orebodies. The paper discusses the possible problems（ contour correspondence and contour connection）in several kinds of reconstructions and puts forward the algorithm of contour reconstruction that is suitable for modeling of geological body seetion, section-based 3D geological modeling process,line frame plane model of geological body and corresponding geological block model.
