基于多元图像分析的包装罐内壁缺陷检测（Packaging Cans Inner Surface Inspection System Based on Multivariate Image Analysis）
包装罐 机器视觉 缺陷检测 区域提取
2009/8/11
为提高包装罐生产线内壁缺陷检测准确性与可靠性，研究了一种采用单摄像机的内壁缺陷检测系统。利用基于形态学的区域提取算法，从罐内图像中分割出内壁检测区域图像。提出基于多元图像分析(MIA)的内壁缺陷检测算法。利用图像融合构成环形合格样本图像，消除罐内焊缝区域的影响，把多个环形合格样本图像与测试样本内壁检测区域图像堆叠起来，用重合区域的图像构造多元测试图像。用基于主成分分析(PCA)的多元图像处理方法获...
