Research on Edge Detection Algorithm of Color PCB Image
Author(s): 
Pages: 113-115
Year: Issue:  13
Journal: Video Engineering

Abstract: 在以图像处理技术为核心的PCB自动光学检测系统中,图像的边缘检测占有重要的地位,并且彩色图像提供的边缘信息更丰富.提出了一种检测彩色PCB图像边缘的方法.首先将彩色图像由RGB空间转换到HSI空间,然后应用基于中心样条滤波和4个模板方向的Sobel算子计算梯度幅值的改进Canny算子,分别对HSI的三分量检测其边缘,并将其结果融合成最终的图像边缘.实验结果表明,算法能成功检测出彩色PCB图像的边缘...
