In the era of industrial automation, the emergence of machine vision is the general trend. The so-called machine vision refers to the use of machines instead of human eyes to do measurement and judgment, through the computer to capture images to simulate human visual function, to achieve the extension of human vision. More importantly, machine vision system has some functions of human brain, which can extract information from the image of objective things, process and understand it, and finally be used for actual detection, measurement and control. The use of machine vision detection compared with manual detection has unattainable advantages, below to understand it.

Machine vision online automatic detection has advantages over manual detection:

1, non-contact, non-damage detection, will not damage, scratch products.

2, fast speed, can cooperate with the production line speed, do not delay the production time.

3. Greatly improve the detection efficiency, high product detection accuracy, and improve the shortcomings of manual detection of missed and false detection.

4, stable work, can be 24 hours long time work, no human eye visual fatigue, high work efficiency.

5, reduce costs, automatic machine detection saves a lot of labor costs, for the enterprise to bring considerable benefits.

6, strong applicability, high flexibility, can work in some dangerous environment is not suitable for manual work, such as radiation, toxic gas, high temperature, high pressure, fluid and other dangerous environment, the use of machine vision equipment can avoid personal safety accidents.

In general, compared with manual detection, machine vision has the characteristics of automation, objectivity, non-contact and high precision. Especially in the field of industrial production, machine vision emphasizes the precision and speed of production, as well as the reliability of industrial field environment. It has great application value in repetitive and mechanical work. It is an important step for enterprises to realize automatic production.
