摘　　要：针对氢能燃料电池涂布缺陷检测难度大的问题,提出了基于区域生长与BLOB分析的涂布缺陷图像检测方法。首先对图像进行ROI区域提取及高斯滤波处理,然后利用区域生长分割图像,最后利用Blob分析标记连通区域。实验结果表明,文中方法能够有效检测出氢能电池涂布缺陷,准确率达到检测要求。In view of the difficulty in detecting coating defects in hydrogen fuel cells,an image detection method for coating defects based on region growth and binary large object(BLOB)analysis was proposed.Firstly,the region of interest of the image was extracted and processed by Gaussian filtering.Then,the image was segmented by region growth.Finally,the connected region was marked by BLOB analysis.The experimental results show that the method in this paper can effectively detect the coating defects in hydrogen fuel cells,and the accuracy meets the detection requirements.
