摘要:

本文主要讨论海量影像快速漫游的问题。在现有的影像金字塔的基础上,本文提出了非一致分层分块金字塔结构,提出一种适于此结构的影像数据调度算法。该算法能够实现平移、缩放以及二者相结合的漫游形式。实验表明,本方法能够实现无限量影像数据的实时漫游,保证画面具有最佳的分辨率,并具有较快的速度和较高的平稳性。

Abstract:

This article mainly focuses on the issue of massive image navigation. On the basis of the current technology of image pyramid, a pyramid structure with non-uniform layers and blocks is presented in this article. Then an algorithm for viewing images based on this structure is presented. It can achieve  the navigation forms of panning, zooming and the combination of both. Experimental results shows the algorithm can accomplish real-time navigation on in   finite image data. Images are displayed with the most proper resolution, and the navigation is fast and stable.
