Summarize
Machines are used instead of human eyes for measurement and judgment. Machine vision system is to convert the captured object into image signal through machine vision products (i.e. image capturing device, divided into CMOS and CCD) and transmit it to a special image processing system to get the shape information of the captured object, and convert it into digital signal according to the information of pixel distribution, brightness, color, etc. The image system performs various operations on these signals to extract the target. Characteristic, and then according to other results to control the field equipment action
