The present invention relates to a pinhole inspection system including an inspection device including an illumination, a camera, and a visual processing unit, the visual processing unit including: a first algorithm unit that performs a first feature extraction using a preset first algorithm, the first feature extraction specifying a plurality of first candidate regions in which estimated pinholes are located; a second algorithm unit that performs, using a preset second algorithm, a second feature extraction in which a plurality of second candidate regions in which estimated pinholes are located are specified, and a third feature extraction in which a plurality of second candidate regions in which the estimated pinholes are located are specified; designating a plurality of candidate regions screened by comparing the plurality of first candidate regions with the plurality of second candidate regions as a plurality of third candidate regions in which estimated pinholes are located; and a third algorithm unit for determining whether the pinholes are actually located in the plurality of third candidate regions by using a preset third algorithm.
本发明涉及针孔检查系统,其包括检查装置,所述检查装置包括照明、摄像头以及视觉处理部,所述视觉处理部包括:第一算法部,利用预设第一算法实施第一次特征提取,所述第一次特征提取指定推测针孔所在的多个第一候补区域;第二算法部,利用预设第二算法实施第二次特征提取及第三次特征提取,在所述第二次特征提取中,指定推测针孔所在的多个第二候补区域,在所述第三次特征提取中,将通过多个所述第一候补区域与多个所述第二候补区域的比较筛选的多个候补区域指定为推测针孔所在的多个第三候补区域;以及第三算法部,利用预设第三算法判断针孔是否实际位于多个所述第三候补区域。
