摘　　要：图像的伪彩显示在医疗及工业应用领域均具有极其重要的意义。为实现视频图像的高速伪彩色处理,设计并实现了一种基于Zynq-7000的视频采集、处理及显示平台。该平台采用ARM处理器采集USB摄像头图像,将采集到的图像和处理后的图像缓存到开发板上的DDR3中,在嵌入式Linux下运行Qt上设计的界面程序,实现视频图像的显示。在伪彩色处理中,利用Vivado HLS工具实现对伪彩色算法的优化设计,并将复杂的图像处理算法用FPGA进行硬件加速。测试结果表明,所提出的基于Zynq-7000的伪彩色图像处理系统能够完成视频采集、高速的图像处理以及高清显示。Pseudo color image display in the fields of both medical and industrial application has the extremely important significance.In order to realize the high speed pseudo-color processing of video image,a video collection,processing and display platform based on Zynq-7000 is designed and implemented.This platform adopts ARM processor to collect the USB camera images,the images were collected and processed image cache to DDR3 on development board,under the embedded Linux operation interface program of the design on the Qt,realizes the video image display.In the pseudo-color processing,the optimization design of pseudo-color algorithm is realized by using the Vivado HLS tool,and the complex image processing algorithm is used to accelerate the hardware with FPGA.The test results show that the pseudo-color image processing system based on Zynq-7000 can complete video collection,high-speed image processing and high definition display.
