Abstract
本发明实施例提供一种异形孔检测方法，获取待测孔板的透光图；通过训练好的异形孔检测网络对透光图进行异形孔检测，得到待测孔板的第一异形孔检测结果；若第一异形孔检测结果为检测失败，则通过训练好的缺陷检测网络对透光图进行缺陷检测，得到待测孔板的缺陷检测结果；基于待测孔板的缺陷检测结果，确定待测孔板的第二异形孔检测结果。通过训练好的异形孔检测网络对待测孔板的透光图进行异形孔检测，判断待测孔板是否为现有的异形孔孔板，在待测孔板不是现有的异形孔孔板，通过训练好的缺陷检测网络光图进行缺陷检测，若待测孔板也不是缺陷孔板，则可以确定待测孔板为新异形孔孔板，可以对新异形孔孔板进行不停线检测，提高待测孔板的检测效率。
