生成全景图像是构建虚拟全景空间系统(vps)的重要一步,全景图像能反映用户在某一视点处任意视角所看到的图像。全景图像的生成有三种方法,一是由计算机生成,二是由全景照相机直接拍摄,三是基于很多离散图像生成的全景图像。全景图像根据投影模型的不同,一般可以分为多面体全景图像、球面全景图像和360度柱面全景。



图像的无缝拼接技术作为全景图像生成的关键一步,本文花了比较大的篇幅介绍它的相关算法。图像无缝拼接主要包括图像配准和图像融合两大技术。其中图像配准是图像融合的基础,可以说无缝拼接技术的进展很大程度上取决于图像配准技术的发展。图像配准就是精确找出相邻两张图像中重叠部分的位置,然后确定两张图像的变换关系。
本文分别介绍了几种基于特征的图像配准和基于区域的图像配准的经典算法。图像融合就是将两幅已经配准的图像中有用的信息综合到一幅图像中并以可视化方法现实的技术。本文分别介绍了基于图像灰度、颜色空间变换和变换域的三种图像融合算法。

文章最后对虚拟全景空间以及全景图像的未来做了展望。

Generating panoramic images is an important step in building a virtual panoramic space system (vps). Panoramic images can reflect the image seen by a user at a certain perspective and an arbitrary angle. Panoramic images can be generated in three ways: the first is by computer, another is to take pictures directly with a panoramic camera, and the third is to generate panoramic images based on a number of discrete images. Panoramic images, varying according to projection models, can generally be divided into polyhedral panoramic images, spherical panoramic images and 360-degree panoramic cylinders.

Image seamless splicing technology is the key step in generating panoramic images. In this article, more words are dedicated to presenting its related algorithms. Seamless Image Stitching includes two techniques, image registration and image fusion. Between the two of them, image registration is the basis of image fusion. It can be said that seamless splicing technology, to a large extent, depends on the development of image registration technology. Image registration is to precisely identify the location of the overlaps of two adjacent images, and then determine the transformation relationship between the two images.

This article introduced a number of classic algorithms of feature-based image registration and region-based image registration. Image fusion is the technique in which useful information from two registered images is integrated into one image and presented by the method of visualization technology. This article introduced the image fusion algorithms of gray-scale-based images, color-space conversion and transformation domain respectively.

Finally, the article did an outlook on the future of panoramic virtual spaces and panoramic images.

Hi cacue

Happy and fulfulling New Year to you.

Wonderful English, a real pleasure to read.

I've set a poll as the only Chinese I can "read" is pluiepoco's name!!
