摘要
当前摄影测量系统软件正向分布式并行处理方向发展,目前大家研究比较多的是在高性能计算机系统(如刀片机)下进行并行数据处理,而研究普通PC机集群分布式并行处理数据则相对比较少。因此本文在多PC机环境下按照分布式处理思想提出了一种对高分辨率卫星影像进行正射纠正的基于中间件模式的分布式并行处理系统,着重叙述了该系统的组成以及任务调度中的相关处理等问题,并在实践中验证了它的可行性。
The development of digital photogrammetry system is forward to distributed and parallel processing. There are many researches on distributed and parallel digital photogrammetry system and a lot of researches are carried out on High Performance Computing system （i. e. Blade） . There are few distributed and parallel research performed in the context of PC clusters. According to the principles of distributed systems, a distributed system of ortborectification of high resolution satellite imagery based on middleware technique is proposed in the context of PC clusters. The paper emphasizes the descriptions of the components in the system and discusses the corresponding strategies of task scheduling and performance in the module. And the feasibility of the system is proved in the practice.
