摘　　要：对于传统实时彩色图像边缘检测算法具有较弱的抗噪能力,并且对于方向较为敏感,获得的边缘细节信息比较粗等问题,本文利用对彩色图像的特点进行分析,提出基于FPGA的实时彩色图像边缘检测系统。利用边缘检测算法方向模板的扩展,使算子对于具有复杂纹理的图像抵抗噪声及适应能力提高。最后对设计的系统进行实验,通过实验结果表示,此系统在处理过程中只是占用了2%的系统硬件资源,资源占用较为合理,并且图像的边缘定位较为精准,具有较强抗造能力,能够将彩色图像边缘提取出来。For the traditional real-time color image edge detection algorithm has weak anti-noise ability,and is more sensitive to direction,the edge details obtained are relatively coarse,etc.,this paper uses the characteristics of color images to analyze,and proposes a real-time color image edge detection system based on FPGA.By extending the direction template of edge detection algorithm,the operator can resist noise and improve its adaptability to image with complex texture.Finally,experiments are carried out on the designed system.The experimental results show that the system occupies only 2%of the system hardware resources in the process of processing.It occupies more reasonable resources.Moreover,the edge location of the image is more accurate,and it has strong anti-manufacturing ability.It can extract the edge of the color image.
