摘要
在进行边坡稳定评估时,通常要求对边坡进行可视化描述,其中最直接的方法就是三维建模。本文以一个在山体后面的露天矿场为对象,使用了一种低空飞行的无人机技术,获取了一组边坡的图像,并将得到的数据进行了处理和运算,最终构建出了一个边坡的三维模型。该方法克服了以往测量中只有一点,以点带面的缺点。利用可视化模型,不仅可以全面展现边坡的总体形状,而且可以着重强调局部的细节,为评价边坡的稳定性提供了一个直观的依据。
When evaluating slope stability,it is usually required to visually describe the slope,and the most direct method is 3D modeling.This article takes an open-pit mine behind a mountain as the object,uses a low altitude flying drone technology to obtain a set of slope images,and processes and calculates the obtained data,ultimately constructing a threedimensional model of the slope.This method overcomes the disadvantage of measuring only one point in the past,with a point to area approach.By using visual models,not only can the overall shape of the slope be fully displayed,but also local details can be emphasized,providing an intuitive basis for evaluating the stability of the slope.
