Abstract
With the rapid development of modern manufacturing industry, the need for automation and intelligence of workpiece detection and identification is increasingly urgent. Machine vision technology, with its advantages of high precision, high efficiency and non-contact detection, has shown great potential in the field of workpiece detection and identification. Based on machine vision technology, this paper deeply studies the construction and optimization of workpiece detection and identification system, aiming at improving the automation level of production line and product quality. This paper describes the basic principle of machine vision technology and its application advantages in workpiece detection and recognition. Machine vision collects the image of the workpiece through the camera, and uses the image processing algorithm to analyze and process the image, so as to realize the accurate recognition and detection of the workpiece. The technology can not only overcome the subjectivity and fatigue problems of manual inspection, but also significantly improve the speed and accuracy of detection, meeting the needs of modern manufacturing industry for efficient and precise production. This paper introduces in detail the design and implementation of workpiece detection and recognition system based on machine vision. The system mainly includes image acquisition module, image processing module and recognition and detection module. The image acquisition module is responsible for acquiring the image of the workpiece in real time and providing data support for the subsequent processing; The image processing module uses the advanced image processing algorithm to preprocess and extract the key information which is conducive to the recognition. According to the extracted feature information, the recognition and detection module can accurately classify and identify the workpiece and detect the defect. In the experimental research part, this paper selects a variety of workpieces for testing, verifying the effectiveness and reliability of the system. The experimental results show that the system can accurately identify the type and attribute of the workpiece, and effectively detect the surface defect and damage of the workpiece, which provides a strong support for the automatic control of the production line. This paper summarizes the research results of workpiece detection and recognition system based on machine vision, and looks forward to the future development direction. With the continuous progress of machine vision technology and the continuous expansion of application fields, it is believed that the system will play an important role in more fields and promote the development of the manufacturing industry to the direction of intelligence and automation.
