摘  要:传统矿山储量核查方法更多是采用人工实地测量和地质勘探法,导致核查结果并不准确。针对上述问题,提出了基于无人机倾斜摄影的矿山储量核查方法:选择五镜头六旋翼无人机开展倾斜摄影,从多角度捕捉矿区信息后优化数据建立三维模型,并将三维模型通过坐标变换和转换矩阵转化为二维坐标,从而进行矿山储量平面图的绘制;最后,使用几何图形法与算术平均法计算出全部矿山储量并与原有矿山储量数据进行比较,实现矿山储量核查。在实验过程中,通过与其他两种矿山储量核查方法进行对比,得出:基于无人机倾斜摄影的矿山储量核查方法的储量计算偏差仅为0.32 kt,另两种方法的偏差分别为146.57 kt和94.08 kt;以上结果说明该方法最为准确。The traditional method of verification of mine reserves is primarily relies on manual field measurement and geological exploration methods,which leads to inaccurate verification results.In order to solve the above problems,a mine reserve verification method based on UAV oblique photography was proposed,a five-lens six-rotor UAV was selected to carry out oblique photography,a three-dimensional model was established after capturing the mining area information from multiple angles,and the three-dimensional model was converted into twodimensional coordinates through coordinate transformation and conversion matrix to draw the mine reserve plan,and finally all mine reserves were calculated by using the geometric figure method and the arithmetic average method and compared with the original mine reserve data to realize the mine reserves verification.In the course of the experiment,by comparing with the other two mine reserve verification methods,it is concluded that the reserve calculation deviation of the mine reserve verification method based on UAV oblique photography is only 0.32 kt,and the deviations of the other two methods are 146.57 kt and 94.08 kt,respectively,indicating that this method is the most accurate.
