摘要: 遥感影像的数量和数据量正在呈几何级数增长,传统遥感影像处理方法已经无法应对这一海量问题。利用新兴的高性能计算集群的超强计算、存储及吞吐能力处理海量高分辨率遥感影像是一种新的思路。在基于云计算的高分辨率遥感影像处理的研究框架下,介绍一种MapReduce遥感影像特征提取方法,实现海量高分辨率遥感影像的海量底层视觉特征的提取。通过在16个节点的Hadoop集群上进行数据量扩展和处理能力扩展实验,证明了基于MapReduce的高分辨率遥感影像底层视觉特征的高效检测与描述方法的高效率及可扩展性。

Abstract: Since the number and amount of remote sensing images is growing exponentially, traditional sensing image processing methods have been unable to deal with this massive growth. The supercomputing, massive storage and handling capacity of the high-performance computing cluster is a new solution to deal with the massive high-resolution remote sensing images. A method of extracting the basic visual features of high-resolution remote sensing images based on MapReduce is proposed. By experiments on the expansion of data amount and processing capacity on a 16-node Hadoop cluster, the MapReduce-based method is proved to be effective and scalable.
