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。 Currently, the photogrammetric system software is developing in the direction of distributed parallel processing. At present, most of the researches focus on the parallel data processing in high performance computer systems (such as blade machines), whereas the research on the distributed parallel processing of data in ordinary PC clusters is relatively a bit less. Therefore, this paper presents a distributed parallel processing system based on the middleware mode for orthorectification of high-resolution satellite image according to the idea of ​​distributed processing in a multi-PC environment, and focuses on the composition of the system and the task scheduling Related issues such as handling, and verified its feasibility in practice.
