The CCD:

English full name: charge-coupled Device Chinese full name: Charge coupled Device

The vision system (CCD for short) is to use machines instead of human eyes to make measurements and judgments. Vision system refers to the machine vision products (that is, image intake device, divided into two kinds of CMOS and CCD) will be ingested target into image signals, transmitted to the special image processing system, according to the pixel distribution and brightness, color and other information, into digital signals; The image system performs various operations on these signals to extract the features of the target, and then controls the equipment action in the field according to the discriminant results. A valuable mechanism for production, assembly or packaging. It has inestimable value in detecting defects and preventing defective products from being distributed to consumers.

The feature of machine vision system is to improve the flexibility and automation of production. In some dangerous working environment not suitable for manual work or artificial vision is difficult to meet the requirements of the occasion, commonly used machine vision to replace artificial vision; At the same time, in the process of mass industrial production, using artificial vision to check the quality of products is low efficiency and accuracy is not high, using machine vision detection method can greatly improve the production efficiency and the degree of automation of production. And machine vision is easy to realize information integration, is the basic technology of computer integrated manufacturing. Can measure, guide, detect, and identify products on the fastest production line, and can complete the production task with quality and quantity.
