基于机器视觉对圆环电阻片外形尺寸和表面缺陷检测进行了研究。分析了电阻片检测要求与图像特征，提出了一种改进的Hough变换求圆环圆心，确定检测区域，采用双圆周法判别尺寸缺陷和内外毛刺；运用数学形态学和斑点分析方法提取表面缺陷，结合缺陷区域的内接圆半径，实现缺陷的准确分类。在VC6.0平台下调用Halcon函数库实现检测算法，根据检测结果将样品分为合格、待检和废品等三种类型。
基于機器視覺對圓環電阻片外形呎吋和錶麵缺陷檢測進行瞭研究。分析瞭電阻片檢測要求與圖像特徵，提齣瞭一種改進的Hough變換求圓環圓心，確定檢測區域，採用雙圓週法判彆呎吋缺陷和內外毛刺；運用數學形態學和斑點分析方法提取錶麵缺陷，結閤缺陷區域的內接圓半徑，實現缺陷的準確分類。在VC6.0平檯下調用Halcon函數庫實現檢測算法，根據檢測結果將樣品分為閤格、待檢和廢品等三種類型。

This study focuses on research of the inspection of shapes and defects on surface for circular re-sistance disc. By referring to requirements and image characteristics, an improved Hough transform has been proposed to determine the center of circle and detection region. Dual circumference method is used to distin-guish size of defects and burr inside and outside;Furthermore, the study uses mathematical morphology and blob analysis to extract defects and classify defects by combining the radius of inscribed circle. The whole implantation is performed on VC6. 0 and Halcon image processing library. Samples are sorted into three cat-egories, up to standard, to-be inspection and waste products, respectively, according to inspection results.
