设计了一种带钢表面缺陷在线检测系统,提出了一种判断在线采集图像中是否存在缺陷的方法,并设计了半封闭图像采集装置,实验证明通过差影图中非零像素点个数的统计,达到了较好的实验效果,证明该方法的可行性。 An on-line inspection system for strip surface defects was designed. A method to judge whether there was a defect in the online image acquisition was proposed and a semi-closed image acquisition device was designed. The experiment proves that the number of non-zero pixels Statistics, to achieve a better experimental results, to prove the feasibility of the method.
