Research of Defect Identification Technology Based on Euclidean Distance Method

通过分析常见的印刷缺陷特征,提出了基于缺陷几何形状和墨量变化共同判断缺陷类型,即通过欧氏距离方法检测缺陷的形状、位置等特征,并设计了一种色度和密度转化算法,来判断印刷缺陷的墨量变化,成功实现了对印刷品缺陷的提取、分类及反馈。

Characters of common printing defects were analyzed. The method to determine the type of defect based on defected geometric shape and printing ink quantity changes was put forward, which used Euclidean distance method to detect shape, position and other parameters of defect. A kind of color density conversion algorithm was designed to judge ink quantity change of printing defect. Printing defect extraction, classification, and feedback was realized.
