基于PCI Geomatica的数字正射影像生成实验及分析

Experiment and Analysis on Making DOM Based on PCI Geomatica

数字正射影像DOM凭借其丰富的景观信息和高质量的几何精度得到了广泛应用。本文以某库区近期拍摄的航片为实验对象,在PCI Geomatica 10.0工作站版软件平台上进行数字正射影像生成实验,并对结果进行分析,最后针对发现的问题提出解决建议,指出在无足够控制点的情况下应尽量采用测区图幅内所有航片直接参与生成DOM。

DOM has been applied widely resorted to its abundant visual information and accurate geometrical precision. This article put some latest aerial photographs as materials, made an experiment and analysis on making DOM based on PCI Geomatica 10. 0 workstation. At last, the author found the solutions to the problems, and he pointed out that：under the circumstances of running short of GCPs, we should adopt all the aerial photographs in measure - area to make DOM directly.
