    摘要:

    针对铁谱磨粒图像识别中存在特征单一、异类特征的综合利用率低等问题,提出一种磨粒图像多特征的异类信息融合识别方法。首先,对在线铁谱图像预处理基础上提取磨粒纹理(ASM、熵、相关、对比度)、颜色(均值、方差、斜度)、几何(7个不变矩)3种统计特征;其次,对提取特征数据进行 [0,1]归一化处理,采用超球心间距法确定核参数,运用超球多类SVM实现基于单种特征的多类磨损识别;最后,在单种特征识别基础上通过后验概率构造3种特征所需的软判决基本概率赋值(BPA)函数,运用超球多类SVM与D-S证据理论结合法实现异类特征融合的铁谱图像识别。特征融合方法识别最高识别率达到了96.1%,与单一特征识别结果相比,识别准确度更高,且实现了不同特征的互补。

    Abstract:

    Aimed at the problems of single feature and low comprehensive utilization of the features of iron spectrum ab- rasive image recognition,a heterogeneous information fusion recognition method for multi-features of abrasive image was proposed. Firstly,based on the pretreatment of the online ferrography images,three statistical features of abrasive grain tex- ture (ASM, entropy, correlation, contrast), color ( mean, variance, slope), and geometry ( 7 invariant moments) were extracted. Secondly,the feature data was extracted and normalized by [0,1],the kernel parameters were determined by hypersphere spacing method,and multi-class SVM based on single feature was used to realize multi-class wear recognition based on single feature. Finally,based on single feature recognition,the soft decision basic probability assignment (PBA) function required to three features was constructed through posterior probabilities,by using hypersphere multi-class SVM and DS evidence theory combination method, the heterogeneous feature fusion of ferrography image recognition was achieved. The highest recognition rate of the feature fusion method reaches 96. 1%,and compared with the single feature recognition result,it has higher recognition accuracy and can realize the complementary of different features
