machine vision

Visual inspection is to use machine instead of human eye to measure and judge. Visual detection refers to converting the target to image signal through machine vision products (i.e. image capturing device, which is divided into CMOS and CCD), and then transmitting it to a special image processing system. According to the pixel distribution, brightness, color and other information, it is transformed into digital signal. The image system performs various operations on these signals to extract the characteristics of the target, and then controls it according to the result of discrimination Equipment action at manufacturing site. It is a valuable mechanism for production, assembly or packaging. It has inestimable value in detecting defects and preventing defective products from being distributed to consumers.

Working principle

The machine vision detection system uses CCD camera to convert the detected object into image signal, which is transmitted to the special image processing system. According to the pixel distribution, brightness, color and other information, it is transformed into digital signal. The image processing system performs various operations on these signals to extract the characteristics of the object, such as area, quantity, position, length, and then according to the preset allowable degree and Output results of other conditions, including size, angle, number, qualified / unqualified, yes / no, etc., to realize automatic identification function.
