Defect image diffusion generation method and device, equipment and storage medium

Abstract

The invention discloses a defect image diffusion generation method and device, equipment and a storage medium, and relates to the technical field of image processing, and the method comprises the steps: determining a target defect type and a defect size parameter corresponding to a target defect according to a natural language prompt text input by a user; building a defect physical vector based on the target defect type and the defect size parameter; adjusting the diffusion noise amplitude in the diffusion process based on the defect physical vector, and generating an initial defect image corresponding to the initial workpiece noise image; and performing physical consistency verification on the initial defect image, and outputting a target defect image according to a verification result. The diffusion noise amplitude in the diffusion process is adjusted based on the defect physical vector corresponding to the target defect, the initial defect image is generated, and the target defect image is output according to the verification result of the initial defect image, so that the problem that the defect image generation method in the prior art cannot pay attention to the physical size of the defect is solved. And the accuracy of the generated defect image is not high.
