The machine vision system can complete inspection work in the same way again and again without feeling tired. In contrast, every time human eyes inspect a product, there will be a slight difference, even if the products are exactly identical.
Due to the physical limitations of human eyes, the machine vision system has obvious advantages in terms of accuracy. Even if human eyes rely on a magnifying glass or microscope to inspect the product, the machine will still be more accurate because its accuracy can reach one thousandth of an inch.
The machine vision system can inspect products faster, especially for high-speed moving objects, for example, on a production line, the machine can improve production efficiency.
There is another fatal flaw in human eye testing, which is the subjectivity brought about by emotions. The test results will change with different moods of workers. However, the machine has no emotions and the test results are naturally very objective and reliable.
Since the working speed of machine vision system is faster than that of humans, an automatic inspection machine can take on the tasks of several people. Moreover, the machine does not need to rest, will not get sick, and can work continuously, so it can greatly improve production efficiency.
The characteristic of machine vision system is to improve the flexibility and automation of production. In some dangerous working environments that are not suitable for manual operations or occasions where artificial vision is difficult to meet the requirements, machine vision is often used to replace artificial vision; at the same time, in the mass industrial production process, manual visual inspection of product quality is inefficient and inaccurate while the use of machine vision inspection methods can greatly improve production efficiency and automation.
