| 摘 要： | 纹理特征反应了物体表面微观几何形貌与颜色的波动程度。针对挠性印制电路(FPC)焊盘纹理特征的提取与检测,本文提出基于灰度与纹理梯度二维分布特征的方法建立描述纹理特征的熵统计量,该统计量能够灵敏地反映、量化焊盘金面正常或异常情况下的不同表面视觉特征,当用于缺陷检测时,可准确地识别出焊盘缺陷,检测准确率高达96.7%,50个焊盘的平均检测时间为300ms,满足在线检测的要求。

| Abstract: | Texture is a very important characteristic which reflect volatility of geometric morphology and color on surface. In order to realize extracting and detecting solder's texture feature and defect, Entropy statistic based on dimensional distribution of grey and texture gradient is proposed to describe texture feature.And it can measure texture effectively and adequately.Then the method is applied to the identification of defect on solder. The algorithm reaches satisfactory results, the accuracy can reach 97.8%, 50 inspecting targets cost 300ms in average.That is very fit for real time inspection. |
