What is Machine Vision?
As a rapidly developing branch of artificial intelligence, machine
vision, in short, uses machines to replace human eyes for
measurement and judgment, and is widely used in various industries.
In the process of large-scale industrial production such as the 3C
industry, the use of artificial vision to inspect products has
problems such as low quality efficiency and low accuracy, and the
use of machine vision inspection methods can greatly improve
production efficiency and production automation.
In the process of product production, manual inspectors must have
keen perception and make accurate judgments on the quality of a
product. It is difficult for traditional manual labor to ensure the
production volume and the quality of the product. The use of visual
inspection equipment for detection can precisely avoid these
problems. It will not cause any damage to the observer and the
observed person, expand the visual range of the human eye, and at
the same time, it can also work for a long time.
Features of Vision Inspection System
1. Accuracy:Due to the physical limitations of the human eye,
machines have obvious advantages in accuracy. Even if the human eye
relies on a magnifying glass or microscope to inspect a product, a
visual inspection system is still more accurate because it can be
accurate to a thousandth of an inch.
2. Repeatability:Visual inspection systems can continuously
complete inspection work without getting tired. In contrast, the
human eye detects a product slightly differently each time, even if
the product is identical.
3. Speed:Visual inspection systems can inspect products faster.
Especially when inspecting objects that are moving at high speed,
such as on a production line, machines can improve production
efficiency.
4. Cost:Since visual inspection systems are faster than humans, an
automated machine vision system can take on the tasks of several
humans. Moreover, the visual inspection system does not need to
stop and can work continuously, so it can greatly improve the
production efficiency.
The composition of system
A machine vision system consists of many related components. A
typical industrial machine vision system has the following parts:
- Light source: It can be understood as the external light of the
human world (sun, fluorescent lamps, candles)
- Lens (fixed focus lens, zoom lens, telecentric lens, microscope
lens): the pupil is the aperture (the size is controlled by the
expansion or contraction of the iris), and the cornea and lens are
like lenses;
- Camera (including CCD camera and CMOS camera): retina
- Image processing unit (or image capture card): retinal nervous
system
- Image processing software: brain
- Communication / input and output unit: limbs and five senses
Inspection principle
The visual inspection system refers to converting the captured
target into an image signal through a CCD industrial camera,
sending it to a dedicated image processing system, and converting
it into a digital signal according to information such as pixel
distribution and brightness; the image system performs various
operations on these signals to extract.
The characteristics of the target, and then according to the
results of the judgment to control the on-site equipment action,
visual inspection, defect detection and system positioning and so
on. Machine vision inspection equipment, CCD vision inspection, and
automated defect inspection equipment are designed to replace
manual quality inspection, improve production efficiency, and
reduce labor costs.
