Machine vision technology is an important branch of computer science. Since its inception, machine vision has been more than 20 years old, and its functions and applications have been gradually improved and promoted with the development of industrial automation.
In the 1950s, statistical pattern recognition of two-dimensional images was studied.
In the 1960s, Roberts began research on 3D machine vision.
In the mid-1970s, the MIT Artificial Intelligence Lab officially launched the "Machine Vision" course.
Since the 1980s, a global research boom has begun, machine vision has flourished, and new concepts and new theories have emerged.
The initial stage was from 1990 to 1998, during which time the real machine vision system market had very little sales. Major international machine vision manufacturers have not yet entered the Chinese market. Prior to 1990, there were only a few laboratories in the universities and research institutes that studied image processing and pattern recognition. In the early 1990s, some engineers from these research institutes set up their own vision company to develop the first generation of image processing products, and people could do some basic image processing and analysis work. Although these companies have successfully solved some practical problems with visual technology, such as multimedia processing, printed surface inspection, license plate recognition, etc., their functionality and reliability in terms of software and hardware are not good enough, limiting their use in industrial applications. Development potential. In addition, an important factor is that the market demand is not large, many engineers in the industry have no concept of machine vision, and many companies do not realize the importance of quality control.
The second phase, 1998-2002, was defined as the introduction period of machine vision concepts. Since 1998, more and more electronics and semiconductor factories, including those invested in Hong Kong and Taiwan, have settled in Guangdong and Shanghai. A complete line of machines and advanced equipment with machine vision was introduced to China. With this trend, some manufacturers and manufacturers began to hope to develop their own visual inspection equipment, which is the beginning of the real machine vision market demand. Equipment manufacturers or OEMs need more external technical development support and product selection guidance. Some automation companies have seized this opportunity and have taken a different path from the development of the image companies mentioned above – to provide international machine vision supply. Business agents and system integrators. They introduced state-of-the-art mature products from the US and Japan, provided professional training consulting services to end users, and sometimes developed a complete set of visual inspection equipment with their business partners.
After long-term market development and cultivation, not only the semiconductor and electronics industries, but also in the automotive, food, beverage, packaging and other industries, some top manufacturers began to recognize the important role of machine vision in improving product quality. At this stage, many well-known vision equipment suppliers, such as: Cognex, Basler, Data TranslaTIon, TEO, SONY began to contact the Chinese market to seek local partners, but meet the requirements of local partners, such as Morningstar.
The third stage has been called the development period of machine vision since 2002. From the following points, we can see the rapid growth trend of machine vision in China:
1. In various industries, more and more customers are looking for visual inspection solutions. Machine vision can solve precise measurement problems and improve their product quality. Some customers even set up their own visual department.
2. More and more local companies are beginning to introduce machine vision into their business, some are general industrial control product agents, some are automation system integrators, and some are new vision companies. Although most of them have not yet fully paid back, they all agree that the machine vision market has great potential. The lack of experienced visual engineers and practical project experience is the main problem they face.
3. Some companies with several years of practical experience gradually position themselves to better develop the machine vision business. They may continue to improve their acquisition card, image software development capabilities, or attempt to become a leader in providing industrial field solutions or visual inspection equipment. Simple agents are still part of their business, but they have begun to develop their own technologies or know-how at the component and system level. 4. After several years of looking for agents, many multinational companies have begun to establish their own branches in China. Usually they set up their own branches in China in Beijing, Shanghai, Guangdong, Shenzhen, etc. to manage key customers and provide technical and business support to partners.
The development of machine vision has not been a single application. The software and hardware products of machine vision have gradually become an integral part of all stages of manufacturing, which puts higher requirements on the integration of the system. Industrial automation companies require integrated industrial automation systems that work with test or control systems rather than stand-alone vision applications. In the modern automated production process, machine vision systems are widely used in the fields of condition monitoring, finished product inspection and quality control.
As a well-known machine vision company in the industry, we have more than ten years of industry experience, specializing in the production and sales of machine vision software and hardware products.
Current status of machine vision industry in major regions
With the global manufacturing center shifting to China, the Chinese machine vision market is becoming an important target market for international machine vision manufacturers after North America, Europe and Japan. At present, the Asia-Pacific region including China and Japan accounts for more than 20% of the global total, surpassing Europe and ranking second in the world.
Machine vision market trends
From the perspective of industrial development life cycle, the international machine vision industry is already in a mature stage. Under the promotion of market hotspots such as Industry 4.0, it is expected that in the next 3 to 5 years, the machine vision technology in Europe, America and Japan will continue to be innovative, the international machine vision market. It is expected to maintain the size of the existing market and continue to grow. The domestic machine vision industry is still in the growth stage. From the perspective of 2014 and 2015, China's machine vision industry has accumulated enough technology, market and industry experience, and has entered a stage of rapid development.
From the perspective of the global market, the machine vision industry has matured. In recent years (2006-2015), the number of patents in the foreign machine vision market has been declining year by year. The global distribution of machine vision patents is mainly concentrated in developed countries such as the United States, Europe, and Japan, and Europe and the United States in the field of machine vision technology is in a dominant position.
Status of domestic patent applications: The number of patents per year has steadily increased. The overall trend of domestic machine vision patents in the southeast coast of 2009-2015 (as of January 2016)
China Industrial Research Network released the 2016-2022 China Machine Vision Market Research Analysis and Development Trend Forecast Report that the number of domestic machine vision patents has increased year by year, and major universities and enterprises have invested in research in the field of machine vision, domestic machine vision. The industry is in a stage of rapid development. The domestic machine vision industry mainly concentrates on coastal developed provinces and Beijing, and the number of patents in Jiangsu, Guangdong, Zhejiang, Beijing and Shanghai accounts for 75% of the total number of applications nationwide.
Number of industrial enterprises: There are more than 100 international machine vision brands in China. China's own machine vision companies also have more than 102 old brands such as Vision Image, and more than 200 machine vision products agents. More than 50 machine vision system integrators, covering all machine vision industry chain products from light sources, industrial cameras, industrial lenses, image capture cards and smart cameras.
Business distribution
At present, domestic machine vision enterprises are mainly located in the Pearl River Delta, the Yangtze River Delta and the Bohai Rim region. The enterprises are mainly distributed in Guangdong, Zhejiang, Jiangsu, Shanghai and Beijing.
Since the beginning of the 1980s, domestic machine vision has been introduced through difficult concepts and entered the development period in 2002. Especially in 2012, the Ministry of Industry and Information Technology issued the “Twelfth Five-Year Development Plan for High-end Equipment Manufacturing Industryâ€. The plan clearly includes intelligent manufacturing equipment as one of the key directions for the development of high-end equipment manufacturing at this stage. From 2013 to 2015, with the rise of concepts such as “Industry 4.0†and “Made in China 2025â€, domestic machine vision companies have sprung up, and the domestic machine vision industry has accelerated significantly. It is expected that the domestic machine vision development period will last until around 2020, and then enter the industrial maturity period.
Machine vision can be said to be the lowest level of infrastructure layer of artificial intelligence. In the application fields of the artificial intelligence industry, the application fields of machine vision are very deep and very numerous. From the perspective of the entire industry chain, China's artificial intelligence industry is in a period of rapid ecological construction.
From the field of machine vision, it is in a fast reconfiguration period. From the perspective of market analysis, machine vision is not a particularly new field. From the earliest image processing to the present, there are many large manufacturers on the market. For a long time, I have been deeply involved in intelligent security and transportation. They started not to do machine vision and face recognition. In these industries, many manufacturers are in the same stage of rapid development.
CCID Consulting predicts that China's artificial intelligence market will exceed 40.6 billion in 2018, and this compound growth rate will reach 25.8%, which is faster than the global growth rate. In terms of market structure, there is also a whole situation. In terms of investment scale, in the past year, the total amount of investment including investment has increased rapidly, and the number of enterprises engaged in artificial intelligence and machine vision has also increased rapidly.
In the future, through the favorable policies of artificial intelligence, there will be relatively big opportunities in these four areas. Security, transportation, finance, and consumer electronics are the application industries that are the focus of machine vision.
The first is that the giants are doing machine vision, including the evolution of artificial intelligence. They are all open to the public. In China, for example, Huawei, for them, the idea of ​​open source, how to use open source, there are many ideas and foreign countries still have A certain gap, a lot of open source to complete the code to package their own use, in fact, from the perspective of the whole idea, the concept of foreign open source is more advanced. Of course, there are reasons behind it. Many companies are basically on the path of open source deployment when submitting artificial intelligence code.
The evolution direction of the entire industry is currently in a period of rapid return. The evolution of the entire industry and product technology will have cyclical fluctuations. The machine vision field and computer vision are still in a fast payback period. That is to say, its technology has matured and the market attention is rapidly rising. It is the future. Key products and areas that can be quickly rewarded.
Finally, in the current development of China's entire market, including the government's planning, the topic of smart city has re-emerged. Many years ago, many constructions were made, but the development was not particularly smooth. Now with the development of artificial intelligence industry, this power The main reason is that the technical strength can solve the real needs and real problems. In terms of data, we predict that there will be more than 500 smart cities in China this year. In terms of industry definition of smart cities, the demand for machine vision is particularly large. The definition of a lot of smart cities is that what is called a smart city is the number of camera heads. This is a very rigid standard. The demand for smart, including camera with face recognition function is very high in the future. big.
