[Abstract]:
In modern industrial automation production, it involves various inspection, measurement and parts identification applications, such as automotive parts size inspection and automatic assembly integrity inspection, electronic assembly line components automatic positioning, beverage bottle cap printing quality inspection, product packaging bar code and character recognition, etc. The common feature of this kind of application is continuous mass production and high requirement for appearance quality.

In modern industrial automation production, it involves various inspection, measurement and parts identification applications, such as automotive parts size inspection and automatic assembly integrity inspection, electronic assembly line components automatic positioning, beverage bottle cap printing quality inspection, product packaging bar code and character recognition, etc. The common feature of this kind of application is continuous mass production and high requirement for appearance quality.

Usually this highly repetitive and intelligent work is done by the naked eye, but in some special cases, such as accurate and fast measurement of small size, shape matching and color recognition, relying on the naked eye can not be carried out continuously and steadily, and other physical quantity sensors can not be competent. With the intensification of industry competition, the control of product quality has not allowed even 0.1% defects. It is necessary to ensure 100% inspection pass rate (i.e. "zero defects") to ensure the sustained and stable growth of performance.

Therefore, people began to consider using CCD camera to grab images and send them to the computer or special image processing module. Through digital processing, size, shape and color can be distinguished according to the information of pixel distribution, brightness, color and so on. This method combines the rapidity and repeatability of computer processing with the highly intelligent and abstract ability of naked vision, which leads to the concept of machine vision detection technology.

Machine vision detection technology is a new testing technology based on computer vision research. Different from the research of computer vision, such as visual pattern recognition and visual understanding, visual detection technology focuses on the geometric size and position measurement of objects. In addition, the detection system of machine vision technology can also automatically detect the whole product, which plays a very important role in controlling product quality and ensuring product quality.

With the development of various industries, in order to better base themselves on the market and enhance the competitiveness of enterprises, more and more enterprises pay attention to the continuous introduction of high-tech. Nowadays, with the development of industrial automation, machine vision technology has been applied more and more widely in the industry, which is more and more recognized and favored by users.
