【摘要】：露天矿工程量计算是露天矿开采过程中的核心技术之一,然而露天矿几何形状由于自然条件以及采矿工艺的影响具有复杂性,工程量难以用传统的方式进行精确计算。提出一种基于无人机倾斜摄影的露天矿工程量计算方法,该方法利用无人机搭载的数码相机获取矿区序列倾斜影像,通过特征提取、空三测量、多视影像密集匹配,在获得密集点云的基础上,构建不规则三角格网和纹理映射,重建出露天矿三维模型,之后通过方格网法实现露天矿工程量计算。选取三门峡渑池某铝矿进行试验,结果表明:该方法能够实现露天矿工程量快速计算,而且具备高效低成本等特点,为复杂条件下快速计算露天矿工程量提供一种新的方法。
[Abstract]:The engineering quantity calculation of open-pit mine is one of the core techniques in the process of open-pit mining. However, due to the influence of natural conditions and mining technology, the geometry of open-pit mine is complicated. It is difficult to calculate the engineering quantity accurately in the traditional way. A method for calculating the engineering quantity of open pit mine based on UAV tilting photography is proposed. The method uses the digital camera of UAV to obtain the sequential tilt image of mining area, and extracts the feature by feature extraction. On the basis of dense point cloud, irregular triangular grid and texture mapping are constructed to reconstruct the 3D model of open-pit mine. The results show that this method can be used to calculate the engineering quantity of open pit mine quickly and has the characteristics of high efficiency and low cost. It provides a new method for calculating the engineering quantity of opencast mine under complex conditions.
