Visual technology monitors the load and temperature changes of bearings in real-time, eliminating the danger of overload and overheating. 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. The biggest characteristics of machine vision technology are fast speed, large amount of information, and multiple functions.
