摘要:
在大规模工业生产过程中,几乎所有产品表面都会负载产品标示的字符信息. 采取字符识别的方式对产品信息进行自动采集及判别在产品的整个生命周期中起着重要作用,因此满足工业现场工况要求的字符识别系统必须具备识别速度快,辨识效率高、鲁棒性好的特点. 基于机器视觉平台MVTec HALCON,结合高级语言编程,设计和开发了铜环产品柱面喷码信息的自动采集及在线识别系统,包含物料输送、图像采集、信息判断及分拣,解决了工业铜环柱面不规则排列字符、扭曲变形字符和模糊字符信息的图像处理和OCR(Optical Character Recognition)字符识别问题. 运行结果表明不规则字符信息一次识别率达到99%以上,实现了铜环产品的生产与检测过程一体化.
Abstract:
The character information about product ID will be attached on the surfaces of almost all of the products in the large-scale industrial production process, and the automatic collection and identification of product ID in the way of character recognition plays an important role in the whole life cycle of the products. To meet the workshop working applications, the character recognition system must have the characteristics of rapid recognition speed, high identification efficiency and good robustness. Combined with advanced language programming,an automatic data collection and online recognition system for the information printed on the dylinder surface copper ring product was proposed based on MVTec HALCON machine vision platform. The proposed system includes parts automated delivery, image acquisition, information judgment and sorting, in which the problems of image processing and optical character recognition(OCR) of characters with irregular arrangement, distortion and blur on the cylinder surface of copper ring was solved. The result indicates that the recognition rate of the irregular character information is up to 99%, and the integration of products producing and detecting process is realized for the copper ring production.
