摘要
为适应星载高光谱成像仪输出数据率越来越高的需求,设计了一种基于模块化的、软硬件结合的高光谱图像实时处理系统。该系统由一个主控模块(MM)和若干个实时高光谱图像处理子模块(SM)组成,对软硬件处理流程进行了合理划分。在充分考虑系统所需选用的DSP和FPGA芯片下,给出了主控模块与子模块的设计方法及原理框图。该系统可等效为一个二维网孔型并行模型,具有很高的并行性和加速比,具有实现实时高光谱图像处理的能力。并且该系统具有很强的适应能力,可满足不同星载高光谱成像仪的需求。
In order to meet the increasingly high demand of spaceborne hyperspectral imager output data rate,the hyperspectral image real-time processing system based on modular,combination of hardware and software is designed. The system consists of a main control module （MM） and a plurality of real-time hyperspectral image processing module （SM）, and the hardware and software processes are reasonably divided. By fully considering the system required the selection of DSP and FPGA chips,the main control module and the module design method and the principle can be equivalent to a two-dimensional mesh parallel model,has high parallelism and speedup,has realized the real time image processing ability. And the system has strong adaptability, can meet the needs of different snaeehnrne hyperspectral imager demand.
