DEFECT DETECTION METHOD, DEFECT DETECTION APPARATUS, LEARNING METHOD, PROGRAM, AND RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To execute defect detection of different images with time and accuracy of a substantially same level.SOLUTION: A defect detection method includes: a step for receiving an input image of an industrial component; a step for receiving a model type for the input image; a step for acquiring a model image corresponding to the model type; a step for estimating inter-image transformation between the model image and the input image; a step for acquiring a positioned input image and a positioned model image by transforming the model image and the input image to a common coordinate system based on the estimated inter-image transformation; a step for forming a plurality of image difference vectors for the input image and the model image; and a step for applying a statistical classification model for generating a labeled classification map for the input image to the plurality of image difference vectors.
