Machine vision is a branch of the development of artificial intelligence technology, is to use the machine instead of the human eye to do measurement and judgment, machine vision system refers to the video image intake device, image acquisition (CMOS and CCD), the capture to the image, and then the image to the processing unit, through digital processing, according to the pixel distribution and brightness, color, size, shape, color, and then according to the results of discrimination to control production equipment action, achieve the purpose of control and auxiliary manufacturing process. Machine vision is a comprehensive technology, including image processing, mechanical engineering technology, control, electric light lighting, optical imaging, sensors, analog and digital video technology, computer software and hardware technology, a typical machine vision application system including vision controller, visual and image digital acceleration card, image capture camera, motion control card, light source system, intelligent judgment decision module, visual software and algorithm, mechanical control execution module.
The wide application of the machine vision system will greatly improve the production efficiency and the degree of automation. In some dangerous working environment that is not suitable for manual operation or where artificial vision is difficult to meet the requirements, machine vision replaces artificial vision. In the process of mass repetitive industrial production, the machine vision detection method can greatly improve the efficiency and automation of production. For example, in the production process of printing and dyeing and textile industry, the quality detection of cloth, which is highly repetitive and has certain comprehensive judgment requirements, increases huge labor costs and management costs to enterprises, but cannot guarantee 100% inspection pass rate (i. e., "zero defect"). In the modern textile and printing and dyeing industry, with the rapid development of artificial intelligence and intelligent manufacturing, machine vision is used to automate and intelligently transform production, making the cloth production line into a fast, real-time, accurate and efficient assembly line. Realize the full automation of the color, quantity and defect detection of all the cloth on the assembly line. Using the automatic identification technology of machine vision to complete the work completed by manual, greatly improve production efficiency and product quality.
