基于无人机倾斜摄影的矿山边坡空间特征分析

Analysis of Spatial Characteristics of Mine Slope Based on UAV Tilt Photography

在对边坡采集数据时,传统测绘方式受场地影响,有时难以进入现场,耗费大量劳动力,且作业时间长,难以保障测量数据的时效性和精确度。利用无人机进行航测不但可以节省大量的人力物力,而且能够保证数据的精度,为后期各种数据分析带来便利。因此,以广东省广州市花都区某露天矿山边坡倾斜摄影数据为依托,制作边坡的三维模型进行坡度分析、平整度分析、水平度分析等,并结合地质环境对其稳定性进行评估,以期为边坡治理提供数据支持。

When collecting data for slope,the traditional surveying and mapping method is affected by the site,sometimes it is difficult to enter the site,consume a lot of labor and takes a long time to work,it is difficult to ensure the timeliness and accuracy of measurement data.Using UAV for aerial survey can not only save a lot of manpower and material resources,but also ensure the accuracy of data,which brings convenience to various data analysis in the later stage.Based on the slope tilt photography data of an open-pit mine in Huadu District,Guangzhou,this paper makes a three-dimensional model of the slope for slope analysis,flatness analysis and levelness analysis,and makes a simple evaluation of its stability in combination with the geological environment,so as to provide data support for slope treatment.
