一种针脚弯曲检测方法应用至插槽。插槽包含复数个针脚。针脚弯曲检测方法包含：产生关于插槽之二值化影像，其中二值化影像具有针脚矩阵图案；基于针脚矩阵图案的轮廓特征产生复数个参考线；基于参考线于二值化影像上计算复数组参考点，其中复数组参考点分别对应针脚；判断每一组参考点的灰阶值是否为255；以及若否，则判定插槽为严重不合格。; generating a plurality of reference lines based on contour features of the pin array pattern; calculating a plurality sets of reference points on the binary image based on the reference lines, in which the sets of the reference points respectively correspond to the pins; determining whether gray-scale values of each sets of the reference points are 255; and if negative, determining the socket as serious fail. |
