【概要描述】In automated production, machine vision system detection is very important, because machine vision detection can replace manual detection, automatic detection, machine vision system detection in the entire automation industry occupy what position? In modern industrial automated production, it involves a variety of detection, measurement and parts identification applications, such as the size detection of auto parts and automatic assembly integrity detection, positioning of electronic assembly line components, beverage bottle cap printing quality detection, product packaging bar code and character recognition are the common characteristics of these applications, are continuous batch production, The quality of appearance is very high. Usually, this highly repetitive and intelligent work is completed by the naked eye. However, in some special cases, such as accurate and rapid measurement of small size, shape matching and color recognition, the naked eye cannot be stable at all, and other physical quantity sensors cannot be realized. With the intensification of industry competition, the company does not even allow 0.1% defects in product quality control. Therefore, it is necessary to ensure 100% inspection compliance rate (i.e. "zero defects") to ensure product continuity. Therefore, people began to consider using CCD camera to capture the image, and send it to the computer or special image processing module, and through digital processing, according to the pixel distribution, brightness, color and other information to determine the size, shape, color, etc., this method combines the speed and repeatability of computer processing with the naked eye vision of high intelligence and abstract ability. Thus forming the concept of machine vision detection technology. Machine vision system detection technology is a new testing technology based on computer vision research. Different from visual pattern recognition and visual understanding in computer vision research, visual detection technology focuses on the measurement of the geometric size and position of objects, such as the three-dimensional size of white objects, the rapid measurement of the three-dimensional shape of the mold, the coaxiality measurement and coplanar measurement of large workpieces. In addition, the detection system of machine vision technology can automatically detect the whole product, which is also very important for the control and guarantee of product quality. With the needs of market development of various industries, in order to better stand in the market, improve the competitiveness of enterprises, more and more enterprises are focusing on the introduction of high-tech, in the industrial automation progress today, machine vision technology is more and more widely used in the industry, more and more recognized and favored by users.
