中文摘要: 随着信息技术、航天技术的不断发展,遥感影像数据量呈现爆发性增长.针对陕西某测绘所管理影像数据时出现的存储需求量大、读取过程缓慢、图像处理耗时长等问题.本文基于LFU (Least Frequently Used)缓存算法,设计了三级缓存模块,用来高速缓存影像数据.同时结合Hadoop开源技术,设计了遥感影像业务管理系统.该系统具有高内聚,低耦合,扩展性强的特点.经过系统性能测试,该系统能有效解决影像存储瓶颈,同时能提升影像读取速度,缩短影像处理时间.
Abstract:With the continuous development of information technology and aerospace technology, the amount of remote sensing image data has shown an explosive growth. The problem of large storage requirements, slow reading process, and long image processing time has been faced with the management of image data by a surveying and mapping facility in Shaanxi. Cache algorithm is designed with a three-level cache module used for cache image data. At the same time, combined with Hadoop open source technology, a remote sensing image business management system is designed. The system has high cohesion, low coupling, and strong scalability features. Testing shows that the system can effectively solve the image storage bottleneck, while improving the image reading speed and shorten the image processing time.
