Characteristics of machine vision systems

With the development of the automation industry, machine vision systems are widely used in assembly positioning, product quality inspection, product identification, product size measurement, etc. It also improves the flexibility and automation of production. In some dangerous working environments that are not suitable for manual work or in situations where artificial vision cannot meet the requirements, machine vision is often used to replace artificial vision; at the same time, in the process of mass industrial production, using artificial vision to inspect product quality is inefficient and inaccurate. , using machine vision inspection methods can greatly improve production efficiency and production automation. Below, the editor of Chengdu Xinxiwang briefly introduces the characteristics of the machine vision system :

(1) Repeatability - The machine can complete the inspection work in the same way again and again without getting tired. In contrast, the human eye will examine a product slightly differently each time, even if it is exactly the same.

(2) Accuracy - Due to the physical limitations of the human eye, machines have obvious advantages in accuracy. Even though the human eye relies on a magnifying glass or microscope to inspect a product, a machine is still more precise because it is capable of precision down to a thousandth of an inch.

(3) Speed machine can detect products faster. Especially when detecting high-speed moving objects, such as on a production line, the machine can improve production efficiency.

(4) Objectivity - There is another fatal flaw in human eye detection, which is the subjectivity brought by emotions. The detection results will change according to the mood of the workers, while the machine has no emotions, so the detection results are naturally very impressive and reliable. .

(5) Cost - Since machines are faster than people, one automatic inspection machine can take on the tasks of several people. Moreover, the machine does not need to stop, will not get sick, and can work continuously, so it can greatly improve production efficiency.
