摘要
根据实际航摄项目,介绍了同时涉及丘陵地、山地、高山地及特殊地类(大面积森林和高山)的航摄作业区的数字正射影像图(DOM)的制作。在DOM制作过程中,结合内业制作和地形特点,提出了不同的像控点布设方案。根据航摄区实际情况,共设计了4种像控点布设方案。通过对不同方案下生产的数字正射影像图的精度进行检查和对比,选出在满足精度要求的前提下,同时顾及作业效率和经济成本的最优布设方案,最后总结了此类航摄区像控点的布设特点。
This paper introduces the production of digital orthophoto map in complex terrain based on the actual aerial photography project.In the process of DOM production,combined with the interior and terrain chracteristics,the layout scheme of different image control points are put forward.According to the actual situation,we have designed four schemes of layout of image control points.By comparing the accuracy of production results under different schemes,the most reasonable layout scheme of image control points is selected.At the end of the paper,the characteristics of layout of image control points in aerial photographs of complex terrain are summarized.
