Abstract -
Detecting defect is the most required and important step in the production process. Computer aided defect detection can provide precise and fast solution. Detecting the defective products during production process is both cost-effective and prevents time-loss. In this study, a system is developed to detect defects during hot rolling operation using image processing methods.The rail and profile images are obtained by CMOS camera when they are rolled. By analyzing these images, different types of defects could be identifiedby using the different gray values for defective and non-defective regions. Defective areas cannot be seen clearly on the images with gray values. Therefore, image processing algorithms haveto be used on the obtained images. Defective regionscan be indicated by using colored segmentation. This study is applied in rolling mill of KarabukInc and is shown anfeature identification for rail and profile surface’s defects.
