摘　　要：为加快药用丁基胶垫的生产速度、考虑到丁基胶塞生产工艺和生产技术上的不足,依据对加工车间的实地考察,研究一种基于机器视觉的丁基胶垫切割轨迹方法。该方法以丁基胶垫为研究对象,通过Halcon设计一个基于归一化互相关系数方法的丁基胶垫中圆形胶垫定位算法,对丁基胶垫中的圆形胶垫进行识别定位,通过亚像素精度拟合获取所有圆形胶垫的圆形坐标和半径信息,快速生成丁基胶垫的切割轨迹,搭建出丁基胶垫视觉识别切割系统,并使用Visual Studio2017对该视觉系统进行软件开发。对该系统的切割轨迹进行测试,自动生成切割轨迹信息,并对裁切后的两种圆形胶垫进行质量分析,定位成功率在96%以上,切割圆形胶垫的误差平均值为0.18 mm,满足工厂的加工精度需求。In order to accelerate the production speed of medicinal butyl rubber pads and improve the production process and technology of butyl rubber plugs,a machine vision based cutting trajectory method for butyl rubber pads was studied based on field investigations of the processing workshop.By using HALCON,we designed a positioning algorithm based on normalized cross-correlation coefficient method to identify and locate the butyl rubber pads.This method can quickly generate the cutting trajectory of the butyl rubber pads and build a visual recognition cutting system.By testing the cutting trajectory of the system,the cutting trajectory information can be automatically generated,and quality analysis on the two types of butyl rubber pads after cutting are conducted.The success rate of positioning is over 96%,and the average error of cutting circular rubber pads is 0.18 mm,which meets the processing accuracy requirements of the factory.
