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。
Aiming at the aerial survey of 1: 2,000 low altitude UAVs in 120 km ~ 2 area of a certain bauxite mine, a 3D product quality inspection procedure using DATmatric software to obtain the puncture coordinates and obtain the measured coordinates by GPS is proposed. The standard and method of evaluating the position accuracy of 3D product quality inspection (the error of the object point to the adjacent control point and the error of the height) are mainly described. Finally, the quality of low altitude UAV aeronautical survey digital product is analyzed and evaluated. The UAV aerial survey digital product quality inspection to meet the 3D product quality inspection accuracy requirements.
