Research of semi-automatic statistics of rock mass discontinuity applying laser scanning technology

摘要: 以力丘河某边坡裸露岩体结构面的快速统计为例,提出了利用三维激光测量方法进行岩体结构面的半自动快速统计方法。详细介绍了三维激光扫描仪和高精度GPS的联合测量方法,激光点云数据的坐标转换和边坡表面三角网重构方法。在此基础上,研究了采用三维激光点云数据和三角网数据进行岩体结构面平面方程的半自动拟合方法、岩体结构面法向量和产状的关系等。利用得到的岩体结构面产状快速绘制岩体结构面密度图、玫瑰图、极点图和赤平投影图,得到了该边坡裂隙结构面分布规律和几何信息等。和传统方法相比,该方法具有快速测量和远距离测量的优点,且减少了攀爬高陡岩坡的危险。

Abstract: Taking the rapid statistics of the naked rock mass discontinuity of the slope of the Liqiu river as an example,the semi-automatic rapid statistics method with three-dimensional laser measurement was proposed.The combined measurement method of three-dimensional laser scanner and high-precision GPS,as well as the method of coordinate conversion of laser point cloud data and triangle grid reconstruction of slope surface were introduced.On this basis,the method of semi-automatic fitting applying thr...
