| 摘 要： | 利用基于图像的绘制技术来构建虚拟空间是当前虚拟现实领域中的一项热门课题,而全景图的拼接又是基于图像的绘制技术中的重要研究内容之一,简单的图像合成代替传统的基于三维几何的建模和渲染.提出一种基于粒子群优化(PSO)和互信息量(MI)的全景图拼接算法,首先采用粒子群优化算法寻找包含足够多特征的模板区域,然后利用互信息量实现全景图像的拼接.算法不需要手工指定特征点,可自动对一组图像进行无缝拼接.实验结果表明算法对全景图的拼接具有良好的效果.它不但提高了渲染速度,而且能够有效地克服图像旋转对拼接的影响,是一种快速实用的全景图拼接算法.

| Abstract: | Constructing a virtual space by using the technique of Image-Based Rending(IBR) has now become a hot topic in the research field of virtual reality,and panorama image mosaic is one of the important research contents of IBR,in which a 3D scene is constructed by using image-composing instead of 3D geometry modeling.In this paper,a mosaic algorithm of panoramic image based on particle swarm optimization(PSO) and mutual information(MI) is proposed.Firstly,the algorithm employs the PSO algorithm to search templa... |
