Description

Bearing roller image generation method based on countermeasure generation network
Technical Field
The invention relates to an image processing, deep learning, computer vision and countermeasure generation network, in particular to a bearing roller image generation method based on the countermeasure generation network.
Background
In national economy, the rolling bearing element is a name of an industrial joint and is widely applied to the fields of automobile industry, military equipment, aerospace, instruments and meters and the like. Today, the market demand for high quality products is becoming more stringent, and rollers are important components of bearings, the quality of which plays a crucial role in the performance of bearings. However, in the production process of the bearing roller, due to the influence of equipment and processes, different kinds of defects, such as scratches, holes, cracks and the like, often appear on the surface of the product. The surface quality not only affects the appearance of the product, but also more likely affects the functional characteristics of the product, and causes great loss to enterprises, so that the surface defect detection of the bearing roller is very necessary.
The traditional bearing roller surface defect detection method is a manual detection method, and manual detection has many defects, such as limited space and time resolution of human eyes, and easy generation of false detection and missed detection. In addition, manual detection also occupies more human resources, and the production cost of enterprises is increased. In view of the problems of manual detection, an advanced and efficient detection method is needed to replace the conventional manual detection. With the development of technologies such as image processing, pattern recognition and the like, a surface defect detection method mainly based on machine vision is widely applied in a product quality control link. In recent years, artificial neural networks have also been gradually applied to defect detection and identification, and have achieved good results. The idea of deep learning, which can autonomously learn from multiple layers of characterizations of the underlying distribution of modeled data, is derived from an artificial neural network. Compared with the traditional machine vision method, the deep learning can reduce the influence of manually extracted features on the identification precision. Aiming at the problems of complex characteristics and difficult extraction of the target to be detected, the deep learning can also provide a good solution. Due to the excellent performance of deep learning, a lot of research results show that the deep learning has excellent performance in the tasks of feature learning and identification.
Compared with manual detection, the bearing roller surface defect detection method based on deep learning can effectively control the surface quality of products, improve the production efficiency of enterprises, reduce the labor intensity of workers and the production cost, can more accurately detect and identify the surface defects of the products, and has important significance for promoting the development of manufacturing industry, improving the production process of the enterprises and improving the competitiveness of the enterprises. However, deep learning requires a large amount of data, and a bearing roller factory produces an excessively small number of defective products, resulting in insufficient data, and therefore, it is necessary to expand the data set using a countermeasure generation network.
GAN is collectively referred to as a generic adaptive Networks, meaning that the network is generated against. The original GAN is an unsupervised learning method, which skillfully utilizes the thought of 'antagonism' to learn a generative model, and can generate a brand new data sample once training is completed. DCGAN expands the concept of GAN into a convolutional neural network, and can generate picture samples with higher quality.
