摘要
针对目前敏捷型遥感卫星相机输出载荷类型多、数据率高和像素灰阶高等特点,提出并构建了基于实时接口现场可编程门阵列(FPGA)并行处理技术的快视系统,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。经高分多模卫星相机整星测试验证,结果表明:高速实时判读快视系统显著提高了相机数据质量评估的效率。首次实现了遥感图像数据从目视解译到机器全程自动化判读的重大技术跨越,可为后续遥感卫星快视设计提供参考。
Regarding to the features of current agile remote sensing satellite cameras,such as multiple output payload types,high data rates and high pixel gray levels,a fast-view system based on parallel processing technology with real-time interface FPGA is proposed and constructed.The proposed system mainly consists of storage unit,pre-processing unit and high-definition display unit.This system has been verified in the test of GFDM-1 satellite cameras.The results shows that this proposed system greatly improved the efficiency of cameras data quality evaluation.It realized the significant technology progress for data processing,from visual interpretation to automatic interpretation by machine,for the first time.This paper can provide reference for fast-view design of the follow-up remote sensing satellites.
