中文摘要：

针对目前遥感相机输出通道多、数据率高和像素灰阶高等特点，提出并构建了基于现场可编程门阵列（FPGA）并行处理技术的快视系统。该系统主要由存储单元、预处理单元以及高清显示单元等核心部件组成。存储单元采用FP-GA直接控制大容量SATA磁盘阵列实现高速海量存储；预处理单元实时对高速海量图像数据进行缩放、平移和数据融合等操作，克服传统快视系统无法高速处理海量图像数据的技术瓶颈；高清显示单元驱动3台12位显示器进行高灰阶、大幅面无缝拼接显示，弥补以往对高灰阶遥感图像只能截断显示的缺陷。实验结果表明：该系统存储容量达96TB，可对总速率高达19．7Gb／s的12通道12位量化遥感图像数据进行实时记录与无失真显示。系统工作稳定可靠，易于扩展，已成功运用于遥感相机的研制测试中，大大提高了遥感相机的研制效率。

英文摘要：

For the multi-channel data outputs, high data rates and high grayscales of remote sensing CCD cameras at present, a new fast-view system by using parallel processing technology based on Field Programming Gate Array（FPGA） is proposed and performed. The system consists of a high- speed mass storage unit, a pre-treatment unit and a high grayscale display unit. The high-speed mass storage unit directly controls large-capacity SATA disk arrays by using FPGA to implement the high speed storage of mass image data. The pretreatment unit processes the mass image data by zooming, translation and data fusion in real time, by which overcomes the technical bottlenecks of the process-ing speeds of traditional fast-view systems. Moreover, high grayscale, large format and seamless im- age data is displayed on three 12-bit monitors by high grayscale display unit. The results show that the system has a storage capacity up to 96 TB, and can record and display 12-channel CCD image data quantified by 12-bit at the total rate up to 19.7 Gb/s in real-time. The system is reliable, easy to ex- pand and has been successfully applied in many types of development tests of remote sensing cameras.
