摘　　要：通过对图像采集原理的研究,完成了基于FPGA的图像采集模块的设计。在FPGA中完成了控制模块、有效数据提取模块、DDR控制模块、图像去隔行与帧率提升模块及显示模块的设计,实现了图像的解码、存储及显示。整个模块的设计是在软件开发平台ISE10.1下,用VHDL语言编程实现的,并在以XC4VSX25芯片为核心的硬件平台上得到了验证。试验结果表明图像采集模块的设计是有效的,能实时显示相机采集到的图像。Through the study of the principles of image acquisition,a FPGA-based image acquisition module design was completed.The decoding,storage and display of the images were accomplished by the control module,the control module,the effective data extraction module,DDR control module,image de-interlacing and frame rate enhancement module and display module designed in the FPGA.The design of the whole system were implemented in VHDL on the tool of ISE10.1 and validated by the hardware platform which was designed based on the chip of XC4VSX25 manufactured in Xilinx.Experimental results show that the image acquisition module is effective,and can display the image captured by the camera in real-time.
