摘要:【中文】本发明公开了一种基于ORB特征匹配和LK光流法的电池丝印质量检测方法,采集电池丝印图像数据,进行预处理提取电池丝印区域;采用矩形分块的方式进行建模,包括插画部分模板和文字部分模板,基于ORB算法提取模板丝印和待测丝印的特征并匹配,实现对丝印内容的定位;基于形态学的图像差影法进行检测,如果出现误报,使用基于L‑K光流法的扭曲校正检测方法进行二次检测;如果没有出现误报,输出结果图像及检测数据,执行分拣操作。本发明实时性好、检测率高,通过改进传统差影法,并将光流法引入印刷缺陷检测领域内,大大提升了对非精确印刷的适应性与检测率。 【EN】The invention discloses a battery silk-screen quality detection method based on ORB feature matching and an LK optical flow method, which comprises the steps of collecting battery silk-screen image data, preprocessing the image data and extracting a battery silk-screen area; modeling is carried out in a rectangular partitioning mode, the template comprises an illustration part template and a character part template, and the characteristics of the template silk screen and the silk screen to be detected are extracted and matched based on an ORB algorithm to realize the positioning of silk screen contents; detecting by using an image difference method based on morphology, and if false alarm occurs, performing secondary detection by using a distortion correction detection method based on an L-K optical flow method; and if false alarm does not occur, outputting a result image and detection data, and executing sorting operation. The method has the advantages of good real-time performance and high detection rate, and the adaptability and the detection rate of non-accurate printing are greatly improved by improving the traditional differential image method and introducing the optical flow method into the field of printing defect detection.
