摘　　要：为了验证图像采集系统的正确性,设计了一套基于FPGA的图像发生装置。系统将规律变化的图像集成到FPGA片内,结合连续变化的行头和帧头信息,按照一般图像探测器输出的格式进行输出,从而达到检验采集系统的目的。系统以一片Xilinx公司FPGA作为硬件运行平台,使用Verilog-HDL硬件描述语言并采用自上而下的模块化设计对整个系统进行硬件描述。试验结果表明,所设计的图像发生器产生的图像边缘锐利、规律性强,系统复杂度低、易于硬件实现,具有较好工程应用价值。In order to verify the correctness of based on FPGA is designed. Regular image frame-head information is integrated into the the image acquisition system, a set of image generator combined with continuous change of line-head and FPGA chip. Image output is done with the general image detector output format to achieve the purpose of system inspection. One Xilinx Field Programmable Gate Array （FPGA） is chosen as the hardware design platform, and the algorithm is described with Verilog-HDL to perform the modularization design from top to bottom. Experimental results show that image obtained from the system is sharp with strong regularity, low complexity and easy hardware implementation, and has a ~ood en^ineerin~ avolication value.
