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

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...
