摘　　要：实现了基于FPGA与USB的CMOS图像获取与采集系统的设计。介绍了成像系统的结构、CMOS图像获取时序的VHDL程序实现、包含FPGA控制及USB固件与VC接口界面程序等在内的数据传输通路设计以及DirectDraw数字图像的显示等。实验结果表明,成像系统工作正常,数据传输满足USB接口规范与设计要求。A CMOS image acquisition system based on FPGA and USB was designed. The way to carry out the design of the imaging system was introduced in detail. It includes the structure of the imaging system, the VHDL program of CMOS driver timing, the FPGA controller, the USB hardware, the interface VC program and the display of the digital image by Direct Draw. Finally the result shows that the imaging system works properly and the data transmission satisfies the design.
