摘要
如何实现特大图像的快速存储与显示是航测图像数据库应用中的关键问题之一。主要从实现原理、算法流程、快速存储与显示技术三方面讨论了这一问题,给出了以缩略图替代原始图预览、内存流和特大图像动态显示为主要技术的解决方案,最后介绍了一个快速存储与显示实例系统IMAGESee。
It is one of the key problems for the application of aerial survey image database how to store & display super large image quickly.The paper discusses this from several aspects,including the theory of realization,flow of arithmetic and fast storage & display technique and presents three primary techniques for this problem which are thumbnail preview instead of itself,memory stream and dynamic display of super large images.Finally,a system developed by the authors according to the project is presented as an example.
