摘  要:通过无人机对露天矿山进行航空摄影测量,对所得的图像数据进行特征提取、空中三角测量,之后利用提取的特征进行特征匹配,建立矿区实体的三维几何模型,计算开采的工程量。通过与传统RTK测量方式和三维激光测量方式对比,可以看出使用无人机测量方式无论是在内业还是外业上均有优势,外业上可以节省人力,缩短外业时间,并且还可以有效保证人员在工作中的安全;在内业上,需要的数据处理时间虽然与采用RTK测量方式所需要的时间大致相同,但采用无人机方式测量的数据处理大部分是由电脑自动化完成,不占用人工时间,所以无人机测量的优势非常明显。UAVs are used for aerial photogrammetry of open-pit mines,and feature extraction and aerial triangulation are performed on the obtained image data.After that,the extracted features are used for feature matching to establish a three-dimensional geometric model of the mining entity and calculate the amount of mining.By comparing with the traditional RTK measurement method and 3D laser measurement method,it can be seen that the use of drone measurement methods has advantages in both management and actual mining.In actual mining,manpower can be saved,field time can be shortened,and personnel safety at work can be effectively guaranteed.In management work,although the data processing time required is roughly the same as the time required to adopt the RTK measurement method,most of the data processing measured by the drone method is completed by computer automation and does not take up manual time.So the advantages of drone measurement are very obvious.
