摘 要 图像拼接技术是将有重叠的两幅图像进行特征提取和匹配最后融合成一幅完整的、宽视角场景的新图像。随着时代的进步，数字成像技术得到了迅速发展，数码成像设备（如数码相机、数码摄像机等数码产品）得到了广泛的应用，但是在实际的生活中图像的宽度并不能达到人们的要求，因而产生了图像拼接技术。本论文所要研究的是解决图像设备本身的限制而没有办法得到一幅比较完整的全景图的数字图像的方法和理论。 本文简要介绍了图像拼接发展的历程、及其现状和在社会中的应用。并且简单的说明了当前常用的图像拼接算法和所面对的问题等，图像拼接的方法可以分为两类，在文中简述了这两类方法的优缺点，但是目前图像匹配最常用的方法是基于特征点的图像匹配，而且这种方法优点是将对整个图像的分析转化为对图像特征点的分析，在文中研究了这种特征点的提取方法，并且论述了基于harris和sift图像拼接的方法。 根据图像之间的匹配关系采用harris进行特征点提取。通过实验验证了本文提出的方法的有效性，此方法解决了在实际生活中因设备问题而不能得到全景图以及图像拼接过程中经常遇见的“拼缝”问题，对于图像拼接技术的应用及研究具有一定的参考价值。 关键词：图像拼接；图像配准；Harris角点检测；图像融合； ABSTRACT Image mosaicing technology is the overlap of two image feature extraction and matching the final integration into a complete, wide Angle scene in the new image. Along with the progress of The Times, obtained the rapid development of digital imaging technology, digital imaging devices (such as digital cameras, digital cameras and other digital products) has been widely used. But the width of the image in the actual life cannot satisfy peoples requirements and thus produce the image matching technology. To research of this paper is to solve the image device itself limits and there is no way to get a picture of a relatively complete panorama of the methodology and theory of digital image. The development of image mosaicing is briefly introduced in this paper, and its present situation and the application in the society And simply shows the current commonly used image mosaicing algorithm and facing problems, Image mosaicing method can be divided into two categories, The advantages and disadvantages of these methods are briefly discussed in the article, But at present the most commonly used methods of image matching is based on the feature points of image matching and this kind of method advantage is the analysis of the entire image is transformed into the analysis of image feature points, In the article mentioned the methods of extracting feature points and Harris and sift image mosaicing method is expounded in the paper According to the m
