基于2D Alpha Shapes自动生成露天矿台阶爆破边界崔年生福建省新华都工程有限责任公司摘 要:为了实现三维可视化环境下露天矿台阶爆破边界的自动生成,首次将2D Alpha Shapes算法应用于爆破边界轮廓线的提取中.先将实测炮孔数据的孔口坐标转化为平面炮孔点,再依据爆破缓冲距离和爆破方向对炮孔点进行偏移,得到炮孔偏移点,最后通过2D Alpha Shapes算法提取炮孔点和炮孔偏移点的外围轮廓线,生成露天台阶爆破边界.实践结果表明:该方法简洁高效,运行稳定,提取精度高,适用于任何形状的爆破区域边界轮廓线提取.关键词:露天矿;爆破设计;爆破边界提取;2D Alpha Shapes;......
