摘要
采用Forman卷积法,基于GPU硬件平台,完成了实时光谱复原处理系统关键技术研究。试验结果表明:系统处理能力为HJ-1A中高光谱解压后下行数据速率的2.82倍,满足实时初级产品与全分辨率移动图像显示处理的技术需求。基于GPU环境对Forman法与Mertz法进行比较,针对Forman法采用不同处理方法进行比较,为开展实用化系统的研制提供了数据与方法。
In this paper, a real-time spectrum reconstruction system of Forman method based on GPU is pro posed. Experiments show that the processing rate of the system is 2.82 times as high as the data rate of HJ-1A satellite and meet the demands of real time generation of primary products and full resolution dis play based on moving window. Forman method and Mertz method are compared based on GPU. In addition, the Forman method is analyzed in three different processing environments. These researches provide neces- sary data and methods to the construction of a practical system.
