Abstract

The application of automatic inspection plays an important role in improving the quality of industrial products. Aiming at nodules on the surface of electrolytic copper plate, this article introduces a comprehensive optical online inspection method. In order to obtain dynamic information of product and overcome the interference of random factors such as large-curvature deformation, position deviation and tilt, the system integrates a variety of single technologies including digital moiré, image recognition and spatial transformation. The online test results show that the system can effectively extract the information of nodules and automatically classify the products according to the set threshold.

摘要

自动化检测的应用对提高工业产品质量具有重要作用。针对电解铜板表面结节，介绍一种综合光学在线检测方法。为了获取产品的动态信息，克服大曲率变形、位置偏差、倾斜等随机因素的干扰，系统集成了数字云纹、图像识别、空间变换等多种单一技术。在线测试结果表明，该系统能够有效提取结节信息，并根据设定的阈值自动对产品进行分类。
