Vision Input System
What Is Vision Input System
Vision systems are a primary consideration for any manufacturer who is looking to improve quality or automate production. Primarily used for online inspection, vision systems can perform complex or mundane repetitive tasks at high speed with high accuracy and high consistency. In easily, a vision Input System is the ability of a computer to see; it employs one or more video cameras, analog-to-digital conversion (ADC), and digital signal processing (DSP).
Information
Human eyes are sensitive to electromagnetic wavelength s ranging from 390 to 770 nanometers (nm). Video cameras can be sensitive to a range of wavelengths much wider than this. Some machine-vision systems function at infrared (IR), ultraviolet (UV), or X-ray wavelengths. Two important specifications in any vision system are sensitivity and resolution. Sensitivity is the ability of a machine to see in dim light or to detect weak impulses at invisible wavelengths. Resolution is the extent to which a machine can differentiate between objects.
The term machine vision is often associated with industrial applications of a computer's ability to see, while the term computer vision is often used to describe any type of technology in which a computer is tasked with digitizing an image, processing the data it contains, and taking some kind of action.
Machine vision is used in various industrial and medical applications. Examples include:
