摘要
随着科学技术的快速发展,人们对于高性能计算技术的需求日益迫切,大规模数据并行处理的集群式系统实现技术开始逐步成熟。我国已对该项技术进行了深入研究,并将其应用到遥感影像处理技术当中,形成了集群式数字摄影测量系统Pixel Grid。相对于传统的摄影测量及遥感影像处理过程,集群式系统整合资源、集成技术,大大提高了数字摄影测量以及遥感影像数据处理乃至空间信息提取的处理效率。这也是目前遥感影像处理技术发展的重要方向之一。
With the rapid development of science and technology, people have an urgent need for high performance computing technol-ogy. The cluster system implementation technology of large scale data parallel processing has gradually matured. China has carried out a thorough study of the technology and applied it to the remote sensing image processing technology, which has formed a cluster digital photogrammetry system called PixelGrid system. Compared with the traditional photogrammetry and remote sensing image processing, cluster based system integration of resources and technology, greatly improved the digital photogrammetry and remote sensing image data processing and spatial information extraction processing efficiency. This is one of the important directions in the development of remote sensing image processing technology.
