摘　　要：针对镭射膜这类反光材料检测困难的问题,提出一种基于视觉伺服的在线检测系统,采用独特的照明和CCD成像技术获取镭射膜的图像,研究一种基于最大梯度的亚象素边缘跟踪算法分析和计算位置偏差,通过视觉伺服运动控制系统实现在线自动纠偏控制。现场运行表明该系统实现了对镭射膜在线纠偏的要求,并在高速生产环境下运行稳定可靠。An online vision-servo based automatic rectification system of laser film was introduced, Particular illumination and CCD imaging technique were used to take the images of the laser film. A robust edge tracking algorithm was employed to analyze the position error of the laser film and online automatic rectification was realized based on vision-servo motion control system. Field operation showed that the system meet the requirement of online automatic rectification system of laser film, and was stable and reliable under high speed production environment.
