To overcome the disadvantages of inefficient,low accuracy,subjective factors,and wasting a lot of labor in artificial detections,with exertion of the machine vision technique to develop the on-line magnetic loop inspection system with IMAQ Vision toolset in Labview(a virtual instrument platform),and a powerful image processing function,IMAQ Vision,to process and analyse properly the image acquired by CCD,such as pattern matching,image extraction,threshold segmentation,filters,gray morphology and so forth.The practice shows that the high efficiency,non-contact,accuracy,stability,controllability of the system played a major role in qua-lity certification and control of magnetic looppart productions,and the system has broad prospects for development and application.
