摘　　要：本文给出了一种基于约束Delaunay三角剖分的三维露天采场模型的生成算法。算法结合采场数据的特点,利用约束Delaunay三角剖分把台阶线、地表特征线等嵌入三角网,使生成的三维模型更接近实际采场,提高了露天采场三维模型的精度,增强了三维显示效果。通过精确的三维可视化显示,可以使矿山工作者形象直观地看到地形和采场布置,从而为矿山生产做出更加科学的决策。该算法能有效地处理各种特殊情况,程序实现简单,符合工程需求。This paper presented an algorithm for 3D open-pit model generation based on constrained Delaunay triangulation. Combining with the characteristics of stope data, the algorithm inserted the step-lines and characteristic lines of terrain into trian- gulation net. The 3D open-pit model could improve the precision and approach the actual stope. The 3D display result was obviously im- proved. Through precise 3D visualization, engineers of mine can observe terrain and stope arrangement straightly in order to make sci- entific decision for the project of mine. The algorithm could effectively deal with all kinds of instances, and be implemented by pro- grams easily, and accord with requirements of the project.
