Abstract
Focusing on the industrial surface defect detection of metal planar and three-dimensional structural ma-terials,this paper summarizes the basic principle and research status of visual defect detection technology,and sum-marizes the key technologies of visual automatic detection system including optical imaging technology,image pre-processing technology and defect detector.Firstly,this paper introduces how to select suitable 2D and 3D optical imaging technology according to the optical characteristics of the test object.Secondly,the important functions of image denoising,feature extraction,image segmentation and image Mosaic are introduced.Then,according to the implementation principle of defect detector,it is divided into five categories:Template matching,image classifica-tion,image semantic segmentation,target detection and image anomaly detection,and the classical algorithms are summarized and analyzed.Finally,this paper discusses the key problems in the implementation of surface defect de-tection in the industrial scene,and looks forward to the development trend of this technology.
