摘　　要：为了实现遥感影像的网络快速发布,提出了一种高效的影像金字塔模型的构建算法,影像的切割与重采样均在内存中运算完成,尽可能地减少I/O操作,从而提高其执行效率。提出了面向Internet的分布式遥感影像的切割算法,并给出了基于B/S架构和基于C/S架构的两种实现方式。为了保证算法的效率与分布式结构,利用C++与Java联合编程进行实现。通过实例对算法性能进行测试,证明了算法的可操作性、实用性和高效性。For quick publication of Remote Sensing （RS） images in Internet, this paper proposed an efficient algorithm to build image pyramid model. In order to improve the efficiency, both the image cutting and re-sampling are implemented in the RAM, avoiding the unnecessary I/O operations. Two distributed implementation approaches under Internet environment are presented, which are based on Browser/Server （B/S） and Client/Server （C/S） architectures respectively. They are programmed by combing C＋＋ with Java, ensuring the processing speed and the distributed architecture of the algorithm. Test results with a global RS image show that the programs can work efficiently, robustly and flexibly under Internet environment. Also, the programs are endowed with user-friendly graphical interfaces and easy to use.
