Problems solved by technology

[0004] 1. Manual detection has high cost, low efficiency, low detection accuracy and unstable detection results
[0005] 2. The existing intelligent detection model based on deep learning requires a large number of samples for model training, but the number of defective samples of industrial products is often very small. In the case of insufficient or few samples, the model training cannot be successful, resulting in subsequent The detection success rate is very low
[0006] 3. When the intelligent detection based on deep learning is directly used in industrial detection, due to the single detection background and insufficient detection feature extraction, it cannot be accurately identified, resulting in low detection accuracy

Abstract

The invention discloses an appearance defect detection method and device for an industrial product and a storage medium. The appearance defect detection method for the industrial product comprises thefollowing steps: acquiring an appearance image of the industrial product to be detected; based on the appearance images, performing appearance defect detection on the industrial product through a pre-trained appearance defect detection model, and training the appearance defect detection model through the following operations: obtaining multiple sample images of a sample industrial product with appearance defects; performing data enhancement on the plurality of sample images by adopting a preset data transformation rule to generate a first sample image set; based on the first sample image set,generating a second sample image set by using a preset DCGAN model; and training an appearance defect detection model by using the second sample image set.

Description

technical field [0001] The present application relates to the technical field of industrial appearance inspection, in particular to an appearance defect inspection method, device and storage medium of industrial products. Background technique [0002] In the field of industrial inspection, appearance inspection is an important content. The quality of appearance affects the quality of products to a certain extent. At present, the degree of automation of appearance inspection is low, and most of them rely on manual inspection. Even in a small amount of inspections that use image processing There are also certain defects in the automation equipment. [0003] The current industrial testing mainly has the following problems: [0004] 1. Manual detection has high cost, low efficiency, low detection accuracy and unstable detection results. [0005] 2. The existing intelligent detection model based on deep learning requires a large number of samples for model training, but the num...
