摘　　要：针对传统航测技术获取矿区三维数字模型成本较高问题,文中提出利用消费型无人机露天矿三维重构的方法.通过多重约束的影像匹配策略少量地面控制点数据进行光束法区域网平差处理获取影像外方位元素信息,利用SFM算法进行低成本快速高效露天矿三维重构方法.结果表明,精度同样满足1:500测图要求.In view of the high cost of acquiring three-dimensional digital model of mining area by traditional aerial survey technology,in this paper,a method of three-dimensional reconstruction of open pit mine was proposed by u・sing consumption-type unmanned aerial vehicle(UAV).Through multi-constrained image matching strategy,a small amount of ground control point data was processed by beam method regional network adjustment to obtain the information of image exterior orientation elements,and SFM algorithm was used to carry out low-cost,fast and effi・cient open-pit three-dimensional reconstruction method.The results showed that the accuracy also met the requirement of 1:500 mapping.
