APPARATUS FOR DETECTING SEEM CRACK OF ROLLED STEEL

摘要

An apparatus for detecting seam crack of a back plate is provided. The apparatus for detecting seam cracks is capable of accurately detecting seam cracks by including: a region of interest setting module for setting a region of interest based on a vertical projection profile for each row of a surface image of a rolled steel; a binarization module for performing binarization on the set region of interest; a candidate region setting module for setting a final candidate region including defects based on the vertical projection profile for each row of the binarized region of interest and a horizontal projection profile for each column; and a seam crack determination module for determining whether defects included in the final candidate region are seam crack defects or not.
