摘要
为了提高边缘定位精度和实用性,本文以FPGA为硬件平台设计了基于改进Sobel算子的实时边缘检测系统.首先,利用CCD相机采集视频并存储到SDRAM存储器中;然后通过改进的Sobel算子对视频每一帧进行边缘检测,运用非极大值抑制算法细化边缘;最后将边缘图像经VGA接口模块进行实时显示.结果显示,本系统边缘定位更加准确,实时性较高.
In order to improve the edge localization accuracy and practicability based on the FPGA hardware platform, this paper designs the real-time edge detection system based on the improved Sobel operator. Firstly, it collects the video by CCD camera and stores it in the SDRAM memory. Then it detects the edge of each frame by the improved Sobel operator, and refines the edge using the non-maximum suppression algorithm. Finally it shows the edge image by the VGA interface module in real time. The results show that this system has more accurate edge localization and high real-time performance.
