随着计算机技术的发展,计算机的存储和处理的功能越来越强大,但是仍然无法满足日益增加的海量信息处理的需要。因此研究如何利用有限的计算机内存,处理无限大小的数据,成为研究的重点。本文根据海量遥感影像数据的特点以及对海量遥感图像进行处理的需要,研究了实现海量图像数据快速显示的方法以及其数据库存储结构。主要包括图像重采样、影像金字塔生成技术、图像快速显示技术等。
Along with the development of computer technology,computer storage and handling ability became more and more powerful,but still couldn't satisfy the needs of mass information processing.Therefore,study how to use the limited computer memory,dealing with the unlimited size of data,become the focus.This paper according to the characteristics of massive remote sensing image data and in its processing needs,studies the fast display method of massive image data and its database storage structure.It mainly includes image re-sampling,pyramid image technique and image rapid display technology,ect.
