Description

Simply put, machine vision is to use machines instead of human eyes to make measurements and judgments. The machine vision system uses machine vision products (i.e. image acquisition devices, which are divided into CMOS and CCD) to convert the captured target into image signals, transmit them to a dedicated image processing system, obtain the morphological information of the photographed target, and convert it into digital signals based on pixel distribution, brightness, color and other information; the image system performs various operations on these signals to extract the characteristics of the target, and then controls the equipment action on site based on the judgment results. Machine vision technology is also used on detection platforms to detect processed workpieces.
