由于地表数据量庞大,矿山地表模型的实时重建是个难题.本文根据矿山开采的特点,通过数据简化、分块、闭合多边形提取和闭合多边形三角化等步骤,较好地解决了矿山大规模复杂虚拟地表模型的动态生成问题.研究和实验表明,该方法简单、快捷,行之有效.%Because of the large volume of surface data , the reconstruction of mine Surface model is a difficult problem in real time, According to the characteristics of mining, Using data reduction, block closed polygon extraction and closed polygon triangulation and other steps, can solve the large-scale mining complex dynamic virtual terrain model generation problems. Research and experiments show that the method is simple, fast and effective.
