摘要

In this learned model generation method, teacher images that include defect maps that are images indicating the distribution of defect parts on a steel surface and have a common image size and information about the presence or absence of periodic defects added to the defect maps in advance are used to generate, through machine learning, a learned model taking, as input values, a defect map that is an image indicating the distribution of defect parts on a steel surface and has the common image size and producing, as output values, values relating to the presence or absence of periodic defects in the defect map.
