Industrial computer application in the field of machine vision So what is machine vision? The so-called machine vision, is to use machines instead of human eyes to do measurement and judgment, is an important part of artificial intelligence, machine vision system is a kind of image signal transmitted by machine vision products to a special image processing system. According to the pixel distribution, brightness and color information, it is converted into digital signals. The image system carries out various operations on these signals, extracts the features of the target, and then controls the action of the field equipment according to the discriminant results. It has the advantages of high degree, high efficiency, high precision, and adapt to the complex environment.

 
Why should machine vision system be used in industrial automation control?
 
First, accuracy - because the human eye is limited by physical conditions, the machine has obvious advantages in accuracy.
 
Two, speed - machine detection products faster. Especially when detecting objects that are moving at high speeds, such as on a production line, machines can effectively increase production efficiency.
 
Another fatal flaw in the human eye test is the subjectivity of emotions, which depends on whether the worker is in a good or bad mood. Machines have no emotions, and the results are, of course, very reliable.
 
Four, cost - because machines are faster than people, an automatic detection machine can undertake the task of several people. And the machine does not need to stop, will not get sick, can work continuously, so can greatly improve the production efficiency.

 
In the application of machine vision, industrial computer has the following advantages:

1, the speed is fast, can move to 1000 meters/min strip appearance for overall detection, the accuracy is 0.1 mm, can also be measured on scattered piece specifications, the speed can reach thousands of pieces per minute.
 
2, industrial control computer quality safety and stability, industrial control computer technology has the characteristics of solid stability, machine vision design can be 24 hours uninterrupted work, with a set of teaching tasks, to ensure that the enterprise product function test is not lost and manual detection of the biggest disadvantage is unstable quality control.
 
3, there is no environmental limit, as we all know, people can not work normally in the face of high temperature, small space and other extreme environment, but machine vision will not exist such a problem.
 
4. Compared to very small electronic components and connectors, usually relying on microscopes and other technologies and low power consumption, machine vision can quickly measure high-power magnifying glasses of any small size.
