活塞包胶组件表面缺陷的机器视觉检测研究

活塞包胶组件是摩托车减震器的重要组成部分，其表面缺陷的人工目测精度低、速度慢。在借鉴国内外研究的基础上，提出了一种基于机器视觉的活塞包胶组件表面缺陷检测系统。硬件方面，设计了光学照明方式，完成了机器视觉系统的研制。软件方面，提出了缺陷检测算法。端面以目标连通域面积为依据判定缺陷，侧面图像则结合组件侧面轮廓分析和连通域特性分析来检测缺陷。实验表明，该系统能够有效的检测出活塞包胶组件的表面缺陷。

Study on Machine Vision System for Inspection of Piston-covering Component

A piston-covering component is a crucial part of a motorcycle’s vibration absorber.The surface defects of the piston-covering components are mainly detected by a manual way.The inspecting results are of low efficiency and poor reliability.Based on literature review,a machine-vision system for inspection of the defects of piston-covering components was designed,including an optical illumination system,experimental devices and the recognition algorithms.Experiments show that,based on the area of the blobs and the contour line of the images,the system can effectively detect the defects of the piston-covering components.
