摘　　要：针对某铝土矿山120 km^2区域1∶2 000低空无人机航测作业,提出利用DATmatric软件获取刺点坐标和通过GPS获取实测坐标进行对比分析的3D产品质量检查的实施步骤。重点阐述了3D产品质量检查的位置精度评定(地物点对邻近控制点的平面位置中误差和高程中误差)标准及方法,最后对低空无人机航测数字产品质量进行了分析和评定,得出本次无人机航测数字产品质量检查满足3D产品质量检查精度要求。In view of the aerial survey by the 1：2000 scale low-altitude unmanned aerial vehicle （UAV） in the 120 km2 area of a bauxite mine, the steps of 3D product quality inspection to obtain the coordinates of the spikes u- sing DATmatric software and to obtain the measured coordinates by GPS are proposed. The position accuracy evalua- tion of 3D product quality inspection （the error of the ground point in the plane position of the adjacent control point and the error in the elevation） standard and method are described emphatically. Finally, the quality of low - level UAV aerial digital products are analyzed and evaluated, and it is concluded that the UAV aerial digital product quali- ty inspection meets the 3D product quality inspection accuracy requirements.
