摘要
针对工业现场中晶振帽的主要缺陷,通过计算机视觉系统来实现缺陷的自动检测。结合晶振帽的缺陷特点,论述了晶振帽缺陷检测系统的构成、图像处理及检测流程,提出一种基于计算机视觉的晶振帽缺陷检测方法。设计了缺陷检测系统的具体软件结构,并用模块化方法实现软件功能。该软件主要包括主程序模块、图像采集模块、图像处理模块和通信模块。实验证明,该检测系统能够准确地实现晶振帽缺陷的检测,满足自动化生产的需要,可在实际生产中代替人工检测。
In this paper, an automatic inspection method based on computer vision technique is presented for detecting the shell surface defects of crystal oscillators. The inspection system configuration, detecting procedure and the image processing algorithm of the defect extraction are detailed. Experiment results illustrate that the proposed automatic inspection method, which has the characteristics of high accuracy and easy implementation, is better than manual inspection method in automatic production process.
