Machine vision is a technology that uses machines to simulate human visual functions, that is, through machine vision products (image capture devices, including CMOS and CCD), the captured target is converted into an image signal, which is transmitted to a dedicated image processing system for various calculations and processing to extract information and analyze it, ultimately used for practical recognition, detection, measurement, and control.

Machine vision technology is an interdisciplinary subject involving artificial intelligence, neurobiology, Psychophysics, computer science, image processing, pattern recognition and many other fields. Machine vision mainly uses computers to simulate human visual functions, extract information from images of objective objects, process and understand it, and ultimately use it for practical detection, measurement, and control.
