Abstract

The invention provides a system for detecting surface defects of a metal plate based on a deep convolution neural network. The system can be used for detecting the surface defects of a metal plate in real time. The system comprises a camera, a mounting frame used for mounting the camera and a processor module, wherein the mounting frame stretches across a conveyer belt on an industrial site; the camera is arranged on the mounting frame and is used for collecting a surface image carried by the metal plate on the conveyer belt in real time; the processor module is used for adopting a deep convolution neural network algorithm for recognizing the defects of the surface image carried by the metal plate collected in real time. The system provided by the invention is suitable for the technical field of machine vision.

Description

technical field [0001] The invention relates to the technical field of machine vision, in particular to a detection system for surface defects of metal strips based on deep convolutional neural networks. Background technique [0002] Metal sheet and strip are indispensable raw materials in industries such as automotive, machine building, chemical, aerospace and shipbuilding. The surface defect of the metal strip refers to the inhomogeneous physical or chemical properties of the local area of ​​the metal strip surface due to the process or other various reasons during the production and processing of the metal strip. Common surface defects of metal strips include roll marks, stains, scratches, holes, leaks, depressions, bubbles, foreign matter, and peeling. Surface defects are parts with high atomic activity, and often become the origin of metal corrosion. The existence of surface defects will greatly reduce the fatigue resistance of parts, damage the quality of parts surfac...
