Machine vision series (01) -- Overview

Artificial intelligence is a national strategy , Machine vision is one of the core fields of artificial intelligence processing , Whether learning machine vision or artificial intelligence , Must have enough knowledge of each other .( short ) A lot of processing on video , It can be said to be the category of machine vision . AI is a tool , Machine vision is the essence ,( short ) Video technology is an application .

Machine vision uses machines to measure and judge instead of human eyes . Machine vision system through machine vision products ( Ingestion device , branch CMOS and CCD Two kinds of ) Convert the captured target into image signal , To a dedicated image processing system , Get the shape information of the object . According to the pixel distribution and brightness 、 Color information , Turn it into a digital signal ; The image system calculates the signal , Extract the features of the target , Carry out relevant processing according to the discrimination results .

Machine vision is a comprehensive technology , Including image processing 、 Mechanical engineering technology 、 control 、 Electric light source illumination 、 Optical imaging 、 sensor 、 Analog and digital video technology 、 Computer hardware and software technology ( Image enhancement and analysis algorithms 、 Image card 、 I/O Card, etc ).

Machine vision improves the flexibility and automation of production . In the field of video technology , Through machine vision technology , Develop interactive video effects .

In the process of mass and repetitive industrial production , Using machine vision detection method can greatly improve the efficiency and automation of production . In the field of printing , At the money printing factory , Machine vision has a wide range of applications .

stay ( short ) Video technology processing , Machine vision also has a wide range of applications , Many video technology special effects processing , All belong to the category of machine vision .

Machine vision is closely related to artificial intelligence , Application of machine vision in China , Mostly stay in the framework application . This series is based on video development technology , Combined with a typical AI framework , About the process of video development , Application of machine vision technology .

The content of this series is not industrial video . Industrial vision is a branch of machine vision , On the whole, Germany and Japan are at the forefront of industrial vision technology . In the manufacture of machine vision system and hardware products , Germany first , Japan second .

Domestic industrial vision research institutions are mainly the Institute of physics and the Institute of automation of the Chinese Academy of Sciences , Most of them depend on foreign hardware products , Conduct relevant research . Its subordinate companies develop vision related systems . Other industrial vision companies act as agents for foreign machine vision products .

             This series focuses on the research and development of machine vision system in the field of radio and television , Prefer artificial intelligence . Other areas of machine vision are not discussed .
