利用正射影像生成立体辅助影像方法比较

Contrast the Methods of Generating Aided Stereo Image using DOM

通过引入投影视差光线,在数字正射影像上制作立体辅助影像,并与原正射影像共同构建立体正射影像对,产生与实地相似的几何模型,进行立体观察与量测,可解决建筑物等细部高度的量测问题。本文介绍了利用正射影像生成立体正射影像对的基本原理,对引入投影视差光线的三种函数模型进行了探讨,给出了成果精度检验及分析结论。

The artificial introduction setting projection parallax light of generating aided stereo images and establishing stereo orthophoto pairs using original digital orthophoto map（DOM） is discussed in this article, which can build similarity geometric model and conduct stereo observation and measure height information on the model surface, providing solutions on practical application for city construction department etc.The principle of building aided stereo geometric model and three artificial introduction parallax functions are also introduced.At last the checked precision of height survey and analytical conclusion are provided too.
