AI Technical Summary

Problems solved by technology

However, the change of the defect is small and difficult to find, resulting in the variation of the marked yield
With the rise of artificial intelligence in recent years, convolutional neural network (CNN) can be effectively applied to image classification, but it is still necessary to mark the category of defects in advance, making the training process more tedious

Abstract

The invention provides an industrial image inspection method and system, and a computer readable recording medium. The method includes: generating a to-be-tested latent vector of a to-be-tested image;measuring a distance between a training latent vector of a normal image and the to-be-tested latent vector of the to-be-tested image; and judging whether the test image is normal or defected according to the distance between the training latent vector of the normal image and the to-be-tested latent vector of the to-be-tested image.

Description

Technical field [0001] The present invention relates to an industrial image detection method, system and computer readable recording medium, and more particularly to an unsupervised industrial image detection method, system and computer readable recording medium based on a generative countermeasure network. Background technique [0002] With the rapid development of industrial automation and products, the number of products that need to be tested is also increasing. The Automated Optical Inspection (AOI) system uses machine vision as the inspection technology and can be used to replace traditional human inspection. In the industrial process, automatic optical inspection can obtain the surface condition of the finished product, and then use computer image processing technology to detect defects such as foreign objects or abnormal patterns. [0003] After the automatic inspection by the automatic optical inspection machine, the inspection personnel may still need to do manual re-jud...
