Research Of Automatic Inspection System For Precision Parts' Surface Quality Based On Machine Vision

Detection based on machine vision technology for digital image processing technology as the core, the smart detection has wide application and broad prospects for development. Detection efficiency for artificial low-impact defects such as subjective, the subject of optical components with the reality of Canadian industry, the detection problem, the developed parts of the surface defect recognition sorting system that uses computer vision image processing technology, automation technology, light mechatronic sorting system of automatic recognition, machine vision based inspection system for surface quality in-depth research.By means of mathematical modeling to establish the signal model of the part surface, the surface detection provides a better theoretical foundation; experiment with various lighting conditions, for different lighting conditions, in theory, algorithm, summed up the quality at the surface for different machine vision-based detection methods, developed a series of image processing and algorithm implementation and research conducted; way coaxial design of the lighting part surface quality automated detection systems, the back part of the selected glasses, both sides of the face, two down Angular six surface defects detection, development of quality criteria for classification, automated sorting.The main subject of the design, development of the part surface quality inspection of image processing software, the software summarizes the lighting, the experimental method and automated detection capabilities. Finally, the experimental system was experimentally tested to verify the effectiveness of the system design to achieve the subject detect the beginning of the development of standards and an improved and prospects.The system can not only meet the surface quality of the selected part of the auto-detection requirements, but also can be adapted to other related industries, the production line, has great room for expansion, the development of related industries play a certain role.
