摘要
数字航空摄影测量技术在3D产品生产与更新中的应用日益广泛,国内外各种航摄仪产品的应用也日益增多,UCX数码航摄仪以其成像精度高、影像清晰、色彩真实等特点成为航空摄影测量的首选设备。本文结合"数字焦作"建设项目,以UCD航空影像为基础,探讨了UCX航摄仪获取的影像数据在制作3D产品中的应用情况,结果表明:UCX在GSD为0.1 m的情况下,其摄影测量的几何精度可满足1∶1 000航测成图规范。
With the increasing application of the international all aerial digital camera products,the application of the digital aerial survey becomes increasingly pronounced in production and renew of 3 D products.UCX camera is of first e-quipment based on its advantages of high precision image,high resolution image,and real colorful image.On the basic of constructive project of digital Jiaozuo,this paper studies the virtual application of 3D product making avail of UCD image data based on UCD camera.The result of that test demonstrates that the geometric precision of UCD can meet the need of air survey mapping regulation with the scale of 1 ∶1000 based on the GSD of 0.1m.
