I. Test efficiency
The rapid development of industrial automation has greatly improved the production efficiency, which puts forward higher requirements for the detection efficiency. The manual detection efficiency is in a fixed range and cannot be greatly improved. In the repeated and mechanized detection process of the assembly line, inspection personnel are prone to fatigue, resulting in reduced detection efficiency. The machine vision inspection equipment can detect products faster, especially when detecting high-speed moving objects in the production line, the machine can improve the detection efficiency, and the speed can even reach 10-20 times that of the manual.

II. Detection accuracy
Due to the physical limitations of the human eye, even relying on a magnifying glass or microscope to detect products will be affected by subjectivity, accuracy can not be guaranteed, and the standards of different inspectors will also be different; The accuracy of the machine has obvious advantages, and its accuracy can reach one thousandth of an inch. Moreover, machine vision inspection equipment is not subject to subjective control, as long as there is no difference in parameter Settings, multiple machines with the same configuration can maintain the same accuracy.
