摘　　要：本文从海量遥感影像数据处理需求出发，结合计算机技术、网络技术和高性能计算技术，提出了一种基于分布式并行计算的遥感影像协同处理系统，并重点介绍了系统的体系结构与组成，分析了GPU—CPU多级协同混合架构、开放武的体系结构、快速计算与存储网络和智能调度策略等系统关键技术，提出了系统的运行流程，为海量遥感影像数据的自动化、规模化处理系统的构建提供了一套有效的解决方案。Considering the photogrammetry processing requirement for massive remote sensing images, this paper proposes a cooperative processing system for remote sensing images based on distributed parallel computation, combining computer technolo- gy, network technology and high capacity computing. Firstly, the architecture of the system is introduced. Then some key tech- niques are analyzed in - depth, including a mixed architecture based on multiple GPU - CPU, open architecture, fast computing and storage network, intelligent scheduling strategy and so on. Lastly, the running process is optimized. The system will conduct effective photogrammetry automatic processing of massive remote sensing images.
