Design of the On-Line Detection System for the Surface of the Hot Heavy Rail

Abstract

AbstractA construction of an on-line detection system for surface of the hot heavy rail is presented, and a kind of detection means based on the machine vision technology is proposed. In the paper, a description of the principle of machine vision detection, the operational principle of CCD and the construction of the system is made. The overall design of the system, including light controls, image acquisition, image processing and man-machine interface management is described in a modularized form. The system has been practically carried out in a Rail Beam Plant. The client in the local area network could observe the image, make information analysis by on-line or off-line, and manage lots of information. Good results have been obtained.KeywordsHot heavy railsurface qualitymachine visionimage acquisitiononline detection
