摘要
荧光磁粉探伤技术在现阶段工业检测领域应用广泛,而对工件裂纹提取方法成为了掣肘荧光磁粉探伤技术发展的一个重要难题。文章提出了一种基于LSD线段检测技术的裂纹区域提取方法。利用梯度方向作为提取的目标图像的主要参量,从而有效地抑制裂纹周围亮度相同的噪点对目标区域干扰。实验结果表明,该方法能够迅速有效地提取出裂纹图像,并有较强的鲁棒性。
Fluorescent magnetic particle inspection technology has been widely applied in the field of industrial tes- ting. However, it is hard to find an effective method to extract workpiece crack from the resulting im- age. The paper proposes a crack region extraction algorithm based on LSD line segment detection. Using the gradient direction as the main parameters of extraction of target image can effectively restrain bright- ness around the same noise interference to the target area. The result of extracting shows that the method can quickly and efficiently extract the crack image and has strong robustness.
