大比例尺数字正射影像图的制作方法及应用方向研究

Research on the Large Scale Digital Orthophoto Map Production Methods and Application

摘要: 航空摄影测量技术已经进入了由IMU/DGPS辅助直接获取影像外方位元素的时代，但是对于航空摄影的成果——数字正射影像图的应用却一直拘泥于地理底图。本文简要介绍了DOM的主流制作方法，然后通过分析和论述提出数字正射影像图可以在三个方向上获得较好的应用：提供承载、提供信息、提供框架。数字正射影像图在现代社会中发挥的作用将会越来越重要，期望本文能为DOM更深和更广泛的提供理论基础和思路。

Abstract: The paper first summarizes the large scale digital orthophoto map (DOM) production methods, and then analyzes the application of DOM. On this basis, the paper proposed there are mainly three application types of DOM, Which in clude: Providing carrier, providing information, and providing a framework. We hope that the paper can lay the foundation for deeper and more extensive application of DOM
