摘　　要：为了解决海雾下采集图像模糊不清的问题,提出了一种CMOS+FPGA+ARM图像采集处理方案。其中图像的预处理部分,针对数据量大、算法不断重复的问题,采用具有并行处理优势的FPGA,提升了系统总体性能。针对高阶的图像去雾算法,采用基于ARM的嵌入式系统进一步实现。FPGA与ARM之间通过DMA传输图像数据,为了解决传输过程中内存分配的问题,系统将DDR进行分块,其中Frame Buffer进行数据交互,剩下的部分用于linux系统。最终实现了基于Zynq-7000去雾的嵌入式系统平台的搭建。In order to solve the problem o f the sea fog under acquisition blurred, proposing an image acquisition deal by CMOS ＋ FPGA ＋ ARM.The image preprocessing part, in view o f the large amount o f data and algorithm＇s repeated prob-lems, the FPGA utilize parallel advantage, it improve the system overall property.The image to fog algorithm for high or-der, further implement the embedded system based on ARM..Interconnection between FPGA and ARM with the DMA＊ In order to solve the problem o f memory allocation in the process o f transmission, the system blocks the D D R , the Frame Buffer uses for data interaction, the rest o f uses for Linux system. Finally achieved to set up the embedded system platform is based on the Zynq - 7000.
