摘　　要：为克服遥感图像预处理计算量巨大,实时处理困难的问题,快速有效地完成图像预处理,以遥感图像预处理中的几何校正为例,集中讨论了基于2D-Mesh的网络拓扑结构对几何校正过程中数据重分布的影响,设计了基于2D-Mesh的并行处理拓扑结构,实现对遥感图像的预处理。该设计改善了遥感图像的并行处理体系结构,很好地提高了预处理系统的性能。Computing load of preprocessing of remote-sensing image is so large that completing calculation in real time becomes very difficult. For completing fast and effective preprocessing, by analyzing key parts of processing progresses, topological structure of parallel process is designed based on 2D-Mesh structure, and processing per-formance is discussed. The design can improve the performance of preprocessing system to a large extent and improve the system sture ture of parallel of remote-sensing image.
