图像配准技术方法研究 摘 要 随着信息技术的迅猛发展，图像配准技术已经在军事、遥感、医学、计算机视觉等多个领域得到了广泛的应用。图像配准技术是图像处理的一个基本问题，它是将不同时间、传感器或视角下获取的相同场景的多幅图像进行匹配的图像处理的过程。三类图像配准的方法大致如下：基于灰度的图像配准方法。基于变换域的图像配准方法。基于特征的图像配准方法。本文将应用这三种方法对图像配准进行研究。并重点研究基于特征的图像配准方法。 关键词 图像配准，特征点匹配，灰度插值，控制点的提取 Abstract The technology of image registration is being widely used in the military, remote sensing , medical, computer, visual and any other fields with the rapid development of information technology. The technology of image registration is a kind of process to match different pictures getting from different periods and different cameras but a same scene, it is a basic point to handle the pictures. There are three kinds of ways to do the image registration:According to the level of the color of gray getting from the pictures.According to transforming domains.According to the features The three kinds of ways will be used to discuss the image registration in the thesis, and the way according to the features will be discussed more in the thesis. Key words: Image registration, Match feature points, Gray inerpolation ,Collect the control points 目 录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc295213285 1.绪论 PAGEREF _Toc295213285 \h 1 HYPERLINK \l _Toc295213286 1.1课题研究目的及意义 PAGEREF _Toc295213286 \h 1 HYPERLINK \l _Toc295213287 1.2国内外对本课题涉及问题的研究现状 PAGEREF _Toc295213287 \h 1 HYPERLINK \l _Toc295213288 2.研究方法与研究内容 PAGEREF _Toc295213288 \h 3 HYPERLINK \l _Toc295213289 2.1研究内容 PAGEREF _Toc295213289 \h 3 HYPERLINK \l _Toc295213290 2.2研究方法 PAGEREF _Toc295213290 \h 3 HYPERLINK \l _Toc295213291 3.图像配准的常用方法 PAGEREF _Toc295213291 \h 4 HYPERLINK \l _Toc295213292 3.1图像配准的定义 PAGEREF _Toc295213292 \h 4 HYPERLINK \l _Toc295213293 3.2 基于灰度的图像配准方法 PAGEREF _Toc295213293 \h 5 HYPERLINK \l _Toc295213294 3.3 基于变换域的图像配准方法 PAGEREF _Toc295213294 \h 6 HYPERLINK \l _Toc295213295 3.4基于特征的图像配准方法 PAGEREF _Toc295213295 \h 8 HYPERLINK \l _Toc295213296 3.4.1特征提取 PAGEREF _Toc295213296 \h 8 HYPERLINK \l _Toc295213297 3.4.2变换模型 PAGEREF _Toc2
