[0114] 2 Convolutional Neural Networks

[0115] 2.1 Basic structure of convolutional neural network

[0116] After the deep learning theory was proposed in 2006, the image feature learning ability of convolutional neural network has received attention, and has developed rapidly with the continuous enhancement of computer computing power and the foundation of massive data in the information age. Convolutional neural network consists of multiple layers, including convolution layer (Convolution Layer), pooling layer (Max-Pooling Layer), full-connection layer (Full-connect Layer) and so on. Among them, the convolution layer is the most core part. In the VGG network proposed by Oxford University, multiple continuous small-size convolution kernels are used instead of large-size convolution kernels to extract image depth features. For example, two 3×3 convolution kernels are used instead of one 5×5 convolution kernel, and three 3×3 convolution kernels are used instead of one 7×7 co...

Abstract

The invention belongs to the technical field of metal corrosion morphology grade judgment, and discloses a corrosion grade information processing method and system based on image recognition, and themethod comprises the steps: obtaining a labeled laboratory metal morphology picture as a data set; carrying out the de-duplication on the obtained training data set, randomly selecting a half of images of each category as a test set, and taking other images as training set images; expanding the training data set, namely carrying out the data enhancement; building a convolutional neural network model by using a Keras framework, carrying out model training, and storing optimal model parameters; and analyzing the grade of the corrosion morphology of the metal surface by utilizing the trained optimal model. According to the method, the judgment of the metal corrosion morphology grade is realized by using a computer vision technology, so the judgment efficiency is greatly improved and the judgment uniformity and objectivity are ensured under the condition of ensuring the judgment accuracy. The method can assist engineers engaged in material research in judging the metal corrosion grade, andvarious difficulties of a previous judgment method are solved.

Description

technical field [0001] The invention belongs to the technical field of metal corrosion appearance grade judgment, and in particular relates to a method and system for processing corrosion grade information based on image recognition. Background technique [0002] At present, in the research experiments on the corrosion of metal materials, the metal coating on the surface will appear rusty characteristics on the surface in the natural environment of the atmosphere. These characteristics are mainly manifested in the presence of a large number of metal surfaces, but the degree of rust varies. By analyzing and processing the characteristic images of the metal corrosion surface morphology, researchers can grade the corrosion level of metal materials and further analyze and study some characteristic behaviors of material corrosion. In the study of corrosion resistance and usability of metal materials, it can provide Broader research avenues. [0003] In the past, the method of j...
