摘要
以研究高速、大容量视频数据的图像处理为目的,利用FPGA为系统控制核心,介绍了基于Camera Link接口的CMOS彩色相机的高速、大容量数据采集的硬件系统组成,重点描述了nand flash的写操作实现原理和方法,并具体给出了由Bayer阵列恢复为RGB信号的彩色插值算法-双线性法。最后,结合ARM-LINUX嵌入式系统简单介绍了基于以太网传输的硬件结构和软件设计。系统运行稳定,通过测试。
In order to research the high speed.large capability image processing,we use FPGA as the system control core, introduce the system hardware of the high speed, large capability data gathering based on Camera Link interface. We mainly gave the writing operation theory of the hand flash,and concretely the Color Interpolation Arithmetic which can resume Bayer to RGB and then carriedout the hardware and software of etbernet based on ARM-LINUX embedded system. The system runs steadily,passes the testing.
