摘要
新型航空摄影仪在摄影测量中的应用已经成为大势所趋。针对新型数码航空影像在摄影测量应用中的高程精度和大重叠度摄影2个问题在理论上进行了分析和讨论,并使用实际数据进行空中三角测量试验,证实在大重叠度数码航摄影像的空中三角测量作业中,只要适当选择影像的地面分辨率,并且连接点转点必须向所有可能的影像转点,是完全可以满足成图精度要求的。
The application of the new aerophotographic instrument in photogrammetry has been the primary trend. There are two points in the photogrammetric application of the digital aerophotographic image ： one is the accuracy of the elevation; the other is the high overlap of the photograph. The first problem can be solved by properly selected GSD of the images; the second problem needs tie points be transferred to all possible images. The experimental result with real UCD images proves these two conclusions.
