基于整体与局部纹理特征加权融合的港机装备钢丝绳断丝缺陷检测研究

钢丝绳是港机装备的重要部件,由于作业工况环境恶劣,钢丝绳表面极易引起断丝等缺陷,影响港机装备作业安全。针对港机装备钢丝绳表面油泥严重、光照亮度不均,以及港机装备钢丝绳断丝缺陷能够在钢丝绳股顶钢丝椭圆形区域内有效体现的特点,提出了一种基于钢丝绳整体纹理特征与股顶钢丝椭圆形区域边缘轮廓纹理特征加权融合的钢丝绳断丝缺陷检测方法。首先采用图像降噪、增强、校正技术对钢丝绳原始图像进行预处理。然后采用图像平滑、阈值分割及边缘特征提取技术对股顶钢丝椭圆形区域边缘轮廓进行提取。接着采用局部二值模式(LBP)算子分别提取钢丝绳整体纹理特征与股顶钢丝椭圆形区域边缘轮廓纹理特征,并对钢丝绳整体纹理及边缘轮廓纹理特征进行特征加权融合。最后对加权融合后的特征向量进行主成分分析(PCA)法降维,并应用支持向量机(SVM)技术对钢丝绳断丝缺陷进行检测。研究结果表明:本文提出的方法对实际工况下重油泥、光照不均等钢丝绳断丝缺陷具有较好的检测效果,具有一定的工程应用价值。
