This paper proposes a new steel strip surface inspection system. The system acquires bright and dark field images of defects by using a stroboscopic IR LED light and area camera system and the defect images are preprocessed and segmented in real time for feature extraction. 4113 defect samples of cold roll steel strips are used to develop KNN (k-Nearest Neighbor) classifier which classifies the defects into 8 different types. The developed KNN classifier demonstrates about 85% classifying performance which is considered very plausible result.

A new neural network classifier is proposed for the automatic real-time surface inspection of high-speed cold steel strips having 11 different types of defects. 46 geometrical and gray-level features are extracted for the defect classification. 3241 samples of Posco’s Kwangyang steel factory are used for training and testing the neural network classifier. The developed classifier produces plausible 15% error rate which is much better than 20-30% error rate of human vision inspection adopted in most of domestic steel factories.

Holographic interferometric tomography has been used to reconstruct the three-dimensional temperature field around a single isothermal cube in an infinite medium. The technique, which mainly consists of interferometric fringe enhancement and analysis and computational tomography, becomes user-friendly by utilizing GUI(graphics user interface) environment. It can also reconstruct the reasonably complex, three-dimensional fluid flow in a relative short period of time. More systematic analysis of the three-dimensional field is underway, and the results will be reported shortly.
