基于ObjectARX的露天矿三维建模技术与可视化研究

本文提出了一种建立带有约束条件的Delaunay三角网方法,即集成了矿山中的散点数据和线状数据,使模型更接近实际,精度更高,完成建立露天矿的三维模型。本论文以魏家峁露天煤矿为应用实例,对三维可视化系统的部分功能进行了开发,包括现状图数据处理、带有约束条件Delaunay三角网的建立、边界处理以及采场三维模型的建立等功能。该系统是以AutoCAD为开发平台,以面向对象的编程语言ObjectARX对平台进行二次开发。系统在魏家峁露天煤矿得到了较好的应用,表明系统具有实用性强、易于操作、模型可靠等特点。

The Study of 3D Visualization Modeling in Surface Mine Geological Model System Based On the ObjectARX

This thesis has given a arithmetic of Delaunay Triangle network with constrained condition,The method was fit for the Open-pit data composed of points and poly-lines.To complete the establishment of three-dimensional model of open-pit mine,CDT model was high-precision and approached actual open-pit.This thesis takes the Weijiabao Surface Mine as an example,to empolder 3D visualization system including data processing of current map,establishing Delaunay triangle network with constrained condition,Border pro...
