摘要

针对现有航空影象纠正软件存在的问题，提出了一种无数字地面模型支持的基于“图象与图形叠加配准”的纠正新方法，并介绍了基于索引模式的图象与图形快速叠加技术，对于影象纠正，在分析航空影象局部变形特点的基础上，提出了对局部变形进行纠正的经验公式，最后，又将初纠正与局部纠正结合在一起，开发了一个完整的图象纠正软件，同时还利用该软件对航空图象进行了纠正试验，纠正时共选择了13个控制点，纠正后的图象与地图叠显示出整体匹配很好，存在的残差也都在2pixel之内，研究结果表明，该纠正方法是可行的，可以用来纠正由各种因素造成的影象变形。

Abstract

This paper firstly analyzes problems existing in current rectification software

then presents a new rectification approach based on image and graphics overlaying and matching without the support of digital elevation model

and introduces fast overlaying technique of image and graphics based on indexed-color mode.To make rectification

this paper analyzes the feature of partial deformation

and presents a rectification formula for partial deformation based on experience.Finally

software of image rectification is developed combined general rectification and partial deformation rectification.In the experiment

a test image is rectified using the software with 13 selected control points

rectified image match the map very well by overlaying

and errors left are all within 2 pixels.The results show that rectification approach this paper presents is feasible and can be used to rectify image deformation induced by any factors.
