摘要

This metal structure phase classification method comprises a feature calculation step for calculating one or more features for pixels of an image capturing the metal structure of a metal material and a phase classification step for classifying a phase in the metal structure in the image by inputting a feature calculated in the feature calculation step to a learned model trained using a feature, to which a label of each of a plurality of phases of the metal structure is added, as an input and the label of each phase as an output, and acquiring the label of the phase in the pixel corresponding to the inputted feature.
