Machine vision uses "machine eyes" instead of human eyes to identify, measure and judge objects. As a rapidly developing branch of artificial intelligence, machine vision has the advantages of high perceptual efficiency and high accuracy.

Compared with overseas, the machine vision industry in China started relatively late, which can be traced back to the 1960s at the earliest. At present, with the in-depth application of algorithm layer and the continuous development of 3D technology, the application of machine vision is developing rapidly.

The demand of localization promotes the maturity of industrial vision.

Machine vision in China can be traced back to the 1960s, but it was not until the middle and late 1990s that machine vision began to enter the stage of theoretical exploration. at that time, machine vision began to be applied in aerospace, military industry, high-end scientific research and other scenes.

Until the beginning of this century, Chinese enterprises mainly represented foreign machine vision devices. In this process, they gradually mastered the simple machine vision software and hardware products, and built a primary application system of machine vision. Since about 2010, the development of AI algorithm has accelerated, which has greatly promoted the development of the machine vision industry. During this period, the machine vision industry has maintained a growth rate of 20% and 30%.

Benefiting from the development of 3D technology, the demand for domestic applications is increasing, and machine vision has entered a period of high development. It is worth mentioning that in 2016, AlphaGo beat the top human chess player Lee se-dol, which marks the depth of the algorithm layer in the field of vision. Subsequently, the popularization of machine vision in the field of intelligent manufacturing has been accelerated, and the industrial application has been unprecedentedly developed.

It can be seen that the machine vision industry in China has roughly experienced the stages of theoretical exploration, industry application and in-depth understanding, and is becoming more and more mature. In this process, the policy played a catalytic role. During the "14th five-year Plan" period, all parts of the country put forward the development goal of the machine vision industry. From a regional point of view, Jiangsu, Zhejiang and Shanghai are mostly engaged in the construction of intelligent factories. Beijing and Guangdong and other places are mostly through intelligent robots to promote the development of machine vision.

In addition, it is worth noting that the demand for localization in the industrial sector also plays a strong role in promoting it. According to public data, the scale of China's industrial automation market exceeded 200 billion yuan in 2020, and by 2021, the market scale of automation and industrial control in China will reach 253 billion yuan, and the speed of localization in the industrial field has been accelerated. the potential market demand for machine vision is increasing, software and hardware technology continues to make breakthroughs, and the overall industry level of industrial vision continues to improve.

02. How is the development now? Machine vision is not a new concept. On the contrary, machine vision has been proposed for many years. In recent years, with the deep application of AI and algorithms, the concept of machine vision has been gradually heated up. Especially in the past two years, China's machine vision market has maintained a high growth trend, mainly due to the upgrading of consumption, the continuous improvement of product quality and quality standards, the increasing demand for testing, and the continuous increase in labor costs. accelerated the development of machine vision.

From the enterprise point of view, by 2020, the number of machine vision and related enterprises in China has exceeded 600, compared with 2010, the number of enterprises has increased as much as ten times. Among them, the proportion of small and medium-sized enterprises with sales below 30 million is the highest, accounting for about 32%, and the number of enterprises with sales of 100 million yuan is the least. In these enterprises, Ling Yunguang, Tianzhun Technology, Gaoshi Technology, moment Technology and other rapid development, sales are also relatively high.

However, compared with foreign manufacturers, because the earliest Chinese manufacturers mainly acted as product agents, and started a little later, foreign manufacturers have stronger design, R & D, and manufacturing capabilities. For example, Conagra in the United States, Basler and Isla in Germany, Keenes and OMRON in Japan, foreign enterprises have also been at the forefront of technological research and development.

However, it should be noted that China is an important part of the global machine vision market, and the market scale has grown rapidly in recent years. According to public data, the overall industry sales reached 14.4 billion yuan by 2020, and it is expected to maintain a growth rate of about 27% this year. Total sales will be close to 30 billion yuan.

On the other hand, the growth rate of foreign machine vision market is relatively slow. by 2020, the global machine vision market has reached US $10.7 billion, and it is expected to grow to US $14.7 billion by 2025, with an annual compound growth rate of about 6.5%.

With its strong discrimination and detection ability, machine vision is widely used in many industries, such as industry, consumer electronics, new energy and so on, and is becoming the basic support of digital and intelligent reform in various industries.

03. Implant eyes into the machine

Machine vision is widely used in various industries, it can also be said that where there is detection, measurement and identification, machine vision can be used, such as in industrial manufacturing, consumer electronics, semiconductors, printing and packaging and other fields.

From the perspective of consumer electronics, because the iteration of consumer electronics products is relatively fast, consumers have higher and higher requirements for the quality of electronic products, so machine vision inspection has become a rigid demand for the development of the industry. China is the largest R & D and manufacturing base of consumer electronic products in the world. in the huge industrial chain, machine vision has covered all aspects, from components and components to overall production. Machine vision is widely used in detection, screening and reading scenes.

Machine vision plays an irreplaceable role in many industries, and the reason is not difficult to understand. if we pass manual identification and detection in all links, first, the current labor cost is relatively high, which will undoubtedly increase the operating pressure of the enterprise. second, manual inspection for a long time, there is great damage to the human eye.

In this case, machine vision through the "machine eye" instead of human eyes, can effectively avoid damage, and work efficiency can also be greatly improved. Thanks to the convenience and efficiency of machine vision, machine vision has landing applications in the fields of new energy vehicles, photovoltaic, robots, lithium batteries and so on.

Machine vision is equivalent to implanting wisdom eyes for machines, and machines can identify every corner of the world. With the gradual deepening of automation and intelligence in the field of industrial manufacturing in China, machine vision will have a broader space for development.
