Industrial Defect Detection Using Modern Computer Vision Techniques

Abstract

The manufacturing process of the industry requires very high quality standards to guarantee reliability and suitability of the product, level of customer satisfaction and economical efficiency of the product. The fact is that even small defects may cause some heavy loss of money, risks, and damaged reputation. Conventional defect inspection systems are often based on manual inspection and classical machine vision methods, which is time consuming, subjective and prone to errors and it is hard to scale into large scale production set ups today. The recent fast development of computer vision technology using the methods of deep learning and artificial intelligence has also changed the nature of automated defect detection systems dramatically. The current computer vision methods including convolutional neural networks (CNNs), transformer networks, and mixed learning systems have shown outstanding results when detecting surface defects, structural deformities and functional defects in many industrial settings. The paper is an in-depth research on the industrial defect detection with the help of the modern computer vision methodology, including the theoretical bases, the current approach methods, and the practical aspect of their implementation. The suggested framework incorporates the advanced image acquisition, preprocessing and deep features extraction, and intelligent classification algorithms to obtain a high level of detection and strong stability in adverse industrial environments. Extensive trials indicate the efficiency of the contemporary vision-based solutions to decrease false positives, accelerate the speed of inspection, and maintain the quality control. The outcomes verify that defect detection systems based on deep learning are far more effective than conventional inspection and can be utilized in practice in the industrial environment on a real-time basis. The paper ends with the determination of the current limitations and research areas to explore in the future in the field of scalable and explainable defect detectors in smart factories.
