高速遥感图像实时质量检测系统设计

摘要

为了实时检测遥感卫星图像数据解压缩后的质量以及数据传送的正确性，设计了一种遥感图像实时质量检测系统。系统由高速嵌入式处理机搭配高性能图形工作站组成，嵌入式处理机基于 cPCI 标准化硬件平台，由8块 TS201 DSP 核心处理器进行并行处理，处理能力高达28.8GFLOPs ；利用大容量 Flash 分布式存储技术进行实时数据的存储，存储容量768GB，存储带宽大于600Mbps ；实验结果表明，该系统可以对传输速率高达120Mbps 的遥感卫星图像进行实时的质量检测。%To detect the quality of decompressed remote sensing satellite image data quality in real-time and the correctness of data transfer,a real-time remote sensing image quality detection system is designed.The system consists of high-speed embedded processing machine and high-performance graphics workstations.The embedded processing machine is based on the cPCI standardized hardware platform,using eight TS201 DSPs to do parallel processing whose speed is 28.8GFLOPs and Flash distributed access technology for large amounts of data storage whose memory is 768GB and bandwidth is 600 Mbps.Experimental results show that the system can detect the quality of the remote sensing satellite image whose transfer speed is 120Mbps.
