Research Status and Development Trend of Crack Recognition Based on Machine Learning

Crack recognition has always been an important research content in the field of machine vision, especially the related automatic detection algorithms have attracted much attention in recent years. As a branch of machine learning, deep learning has shown strong function and flexibility in crack recognition. In this paper, the development, research status and typical methods of crack recognition technology based on machine learning are introduced in detail. Firstly, the applications of various machine learning algorithms in the field of crack recognition are introduced, and the commonly used classifiers such as support vector machine, K-Nearest Neighbor, neural network, decision tree and random forest are introduced from the aspects of feature extraction algorithm and application object. Secondly, the application of deep learning in crack recognition is introduced from the aspects of network model, data set and application object. At the same time, 81 relevant literatures in recent 20 years (2000-2020) are compared and analyzed in this article. It is considered that the recognition of metal cracks is still a hot research in the future, and the mixture of multiple algorithms will gradually replace a single algorithm as the development direction in the future.
