摘要
无人机影像经过处理,可以获取数字正射影像产品.以甘肃某地区超大范围DOM的生产为例,论述了利用PPS后差分系统支持下的CW-30 无人机获取数字航空影像,同时加入外业像控点,在集群式影像处理In-pho8.0 软件下,制作1∶2 000 DOM过程.成果目视检查表明,影像质量良好.精度检测表明,空中三角测量成果的检查点平面中误差为0.272 m,高程中误差为0.234 m;DOM的地物特征点的平面中误差为0.336 m,能够达到相应规范要求.
Abstract
The digital orthophoto map(DOM)production could be obtained by using UAV images.Taking DOM production project in extra large area of a district in Gansu province,this article discusses 1∶2 000 DOM production process using the digital aerial images obtained by CW-30 UAV based on PPS post differential system with the field image control points on the cluster image processing soft-ware Inpho8.0.The results show that the images have fine quality through visual inspection.The DOM accuracy also reaches the rela-tive specification requirements with the planimetric RMSE of 0.272 m and vertical RMSE of 0.234 m in the aerial triangulation result,and planimetric RMSE of element feature points is 0.336 m on the DOM.
