基于图像处理技术的轨道车辆底部视觉检测系统

New Visual Inspection System of Rolling Stock Underside by Image Processing Technique

利用图像处理技术,本文开发了一种用于机车车辆故障检测的系统。该系统能够自动检测诸如底部设备紧固螺栓松动或设备箱盖手柄转动等故障,如有必要,检验人员可以根据该系统显示的图像对机车车辆进行具体检查。目前系统已经具备了车辆底部设备侧面检测功能,我们正致力于将该系统应用于车辆底部设备中间区域及车顶设备的检测。本文对该系统及其用户界面进行了概述。

With image processing technology,we have developed a failure detection system for inspection of rolling stock.In this system,failures such as looseness of bolts fixing underfloor equipment to the car body,and rotation of cover handles of equipment are automatically detected;and if necessary,inspectors can check the rolling stock with images displayed by the system.We have completed development of a system for inspecting the side of the underfloor equipment,and have been working to apply the system for the middle area of the underfloor equipment and for the roof.In this paper,we give an overview the system and user interface of the system for inspecting the side of the underfloor equipment.
