摘　　要：根据采集系统将应用于的工业测量环境的要求,在详细分析SONY公司ICX618面阵CCD(Charge coupled Device,电荷耦合元件)驱动时序及ADI公司AD9949片寄存器配置的基础上,设计图像采集硬件系统。采用一种插值算法,恢复Bayer格式滤波阵列获得的RAW数据,并通过Cameralink接口传至上位机实时显示。整个系统选用FPGA实现控制,使用Verilog HDL对硬件时序进行描述仿真。A real-time hardware system of image acquisition is presented, after analyzing the driving time of the CCD image sensor ICX618 and the register configuration of AD9945. We adopts the bilinear interpolation algorithm to obtain the full-color images from raw data provided by Bayer color filter array, and transmit to host device display. The whole system is implement by FPGA in which the driving time design and simulation is described by using Verilog HDL.
