摘    要:介绍了一种对立方体全景图进行实时交互浏览的基本重投影算法,并在此基础上提出一种基于PDA的立方体全景图实时浏览的改进算法。此改进算法只对关键点进行坐标变换,再把要显示的部分图像根据这些关键点进行变形,等效地完成对所有点的坐标变换,从而实现对立方体全景图的实时浏览。实验结果表明,该方法可以极大地提高浏览速度。

关 键 词:虚拟现实  PDA  全景图像  立方体全景图

Abstract:This paper firstly introduces basic arithmetic of browsing the cubic panorama.Then based on this,the speedup arithmetic is realized on PDA.In the speedup arithmetic,firstly transforming the coordinates of key points,then morphing the image to show according to the key points,which is equal to transforming the coordinates of all the points.In the way,the browsing of the cubic panorama is realized.h is tested that the speedup arithmetic can greatly improve the speed of browsing.
Keywords:PDA
