Abstract

A reasonable detection algorithm for surface defects in bearing rollers was designed based on the analysis of some most common surface defect types． It combines the traditional computer vision method with deep learning and adopts the improved ＲetinaNet model to realize the surface defect detection of bearing rollers． The experimental results show that the accuracy of this method is more than 95%． As compared with the traditional defect detection method，the proposed detection algorithm can make improvement in accuracy，recall rate and F1-score．

Key words： bearing; surface defect; online detection; deep learning; convolution neural network
