摘要
露天矿测量验收主要采用全站仪等单点式测量的方式,存在采样密度低、测量周期较长等不足。针对以上问题,采用三维激光扫描技术在露天矿中获取点云数据,并通过布料模拟算法和三角网计算体积算法,计算得到采剥工程量。经实验验证,与传统三角网体积计算法得到的采剥工程量相比,精度提高了2.3倍。
Open pit survey acceptance mainly adopts single point measurement method such as total station,which has the disadvantages of low sampling density and long measurement period.In view of the above problems,3D laser scanning technology was used to obtain the point cloud data in the open-pit mine,and the stripping quantities were calculated through the distribution simulation algorithm and the triangulation calculation volume algorithm.The experimental results showed that the precision of the proposed method was 2.3 times higher than that of the traditional method.
