摘　　要：针对传统图像处理平台采集、处理速度慢,显示分辨率低,不方便携带等问题,设计了一个基于FPGA的高速图像处理平台,包含高速图像的采集、处理、及显示。图像采集通过Camera Link接口采集图像,图像处理部分利用乒乓操作对图像数据进行高速存储,FPGA完成图像预处理,DSP进行运算复杂的图像处理,图像显示部分输出标准的视频信号进行DVI显示。实验结果表明,平台完成了对图像的高速处理,体积小,处理数据量大,可以替代传统图像处理平台,并应用到多种图像处理领域。In view of the slow speed, low display resolution, and inconvenience to carry of traditional image processing platform, in this paper, a high-speed image processing platform which including high-speed collection, processing and display is designed, based on FPGA. Image collection system collects image through the Camera Link interface and image processing section uses ping-pong operation to store the image data. Then FPGA complete the image pre-processing, such as filtering, image enhancement, etc. DSP performs the complex computational image processing. The image display section outputs a standard video signal for DVI display. Experimental results show that the platform realizes the high speed image processing. It＇s volume is small and the data amount is large. It can replace the tradition- al image processing platform, and applied to various fields of image processing.
