Image data generation method, abnormality detection method, electronic device and storage medium

Abstract

This application provides an image data generation method, an abnormality detection method, an electronic device and a storage medium. The image data generation method includes: obtaining a three-dimensional model of a target object, a reality defect image, and a normal image; generating a synthetic defect image and annotation information of the synthetic defect image based on the three-dimensional model and the reality defect image, the annotation information of the synthetic defect image including distribution information of a defect of the three-dimensional model in the synthetic defect image; simulating and processing the normal image of a target object based on a preset adversarial generative network model, and generating a plurality of simulated defect images; constructing an image fusion dataset based on a plurality of reality defect images, a plurality of synthetic defect images, a plurality of simulated defect images, and the annotation information of each synthetic defect image in the plurality of synthetic defect images.
