Machine vision summary:

Machine vision systems are characterized by increased flexibility and automation in production. Machine vision is commonly used to replace artificial vision in some dangerous working environment which is not suitable for manual work or where artificial vision is difficult to meet the requirements. At the same time, in the process of mass industrial production, the manual vision is used to check the quality efficiency and the precision of the product is not high, and the machine vision detection method can greatly improve the production efficiency and the degree of automation of production. And machine vision is easy to realize information integration, which is the basic technology to realize computer integrated manufacturing.


Machine vision operating principle:

The machine vision detection system uses the CCD camera to convert the detected object into an image signal, which is transmitted to a special image processing system. According to the information of pixel distribution, brightness, color, etc., it is converted into a digital signal. The image processing system performs various operations on these signals to extract the characteristics of the target, such as area, quantity, position, length, and then outputs the results according to the preset permissible degree and other conditions, including size, angle, number, Qualified / unqualified, have / no etc, realize automatic recognition function.
