摘要
如何构建使用简单、功能强大的3D地测CAD系统,实现3D矿床模型的自动生成已成为矿山地质、采矿等部门的设计人员追求的目标之一。鉴于此,综合运用多种数学方法、数据库技术、图形图像处理技术,对3D地测CAD系统的整体框架及其软件实现方法进行了深入研究,对解决3D地测CAD系统中存在的重点和难点问题——矿岩界线的自动绘制和3D矿床模型的自动生成,进行了重点尝试性研究,提出基于空间小三角面的表面拟合技术的3D矿床模型自动生成方法,为矿山地质、采矿人员提供了一个全新的操作平台。
One of the objectives pursued by the designers in departments of mine geology,mining and others has grown to how to build a CAD system of 3D Geological Survey with simple operation and powerful function to realize the auto-formation of 3D deposit models.In view of this,a variety of mathematical methods,database technology,graphics-video processed technology are comprehensively applied to deeply study the overall framework and implementation method with software of CAD System of 3D geological survey.Also the paper took an eventful attempt to research the focus and nodus,automatically drawing the boundaries of mineral rock and auto-formation of the 3D deposit models,in the CAD System of 3D geological survey.Then an auto-formation method of 3D deposit models based on the surface-fitting method of spatial little triangulated surfaces is proposed,which provides a totally new platform for mine geologists and miners.
