利用普通数码相机制作全景图的分析.doc

PAGE 摘 要 全景图像(Panorama)通常是指大于双眼正常有效视角(大约水平90度，垂直70度)或双眼余光视角(大约水平180度，垂直90度)，乃至360度完整场景范围拍摄的照片。除了利用特殊的设备来获取全景图像，目前多采用图像拼接技术。即用普通数码相机配合三脚架拍摄一组有一定重叠度的相片，并利用软件将这些相片拼接成一副高质量的图像。这是当前图像处理的一个热门研究课题。也是基于图像绘制的一部分，适用性很强，应用于虚拟漫游、数字娱乐、旅游展示、远程教育、电子商务等领域。 制作一幅完整全景图包括源图像的采集、特征点的提取、特征点的匹配、图像拼接和融合和全景图像后处理。本文就基于SIFT特征的匹配算法和柱面360°全景图像的生成方法进行了简单的介绍。并利用ArcSoft Panorama Make 5软件对源图像进行处理，得到一幅完整的全景图像。本文实验采集了河南理工大学部分区域的全景图像，并发布到了IE平台上，使得全景图的浏览更具有友好性和沉浸感。 关键词：全景图像，柱面全景图，SIFT，拼接 ABSTRACT The panorama usually refers to the photos taken from the angle which is greater than the available vision angle of eyes（horizontal?? 90°，vertical 70°）or split vision angle of eyes（horizontal 180°，vertical 90°），or even the whole scene domain of?? the angle of 360 °. The image splicing technology is more adopted current except using the special equipment to acquire the panorama.That means the general digital camera coordinating with tripod will take a series of photos with some degrees of overlap and make use of the software to knit these pictures into one high-grade image.This becomes a hot issue for investigation of image processing in modern society，and is also the part of image-based rendering，which is widely used in the areas of virtual walkthrough，digital entertainment，journey displays，distance learning and the e-business and so on. To make a complete panorama includes collecting the source image，drawing and matching the characteristic points，splicing and inosculating the images and reprocessing the panorama.This article makes simple introduction ，which is based on the matching algorithm of SIFT characteristic and the generation method of cylinder 360°.And it makes use of the software ArcSoft Panorama Make 5 to process the source image,from which getting a complete panorama.The experiment of this article adopts the panorama of the subregion of Henan University of Science and Technology and post it on the IE platform，so as to make the panorama more friendly and have the immersion.
