Machine vision is the ability to use optical systems, industrial digital cameras and graphics to process things to simulate human vision and ideas. Automation equipment can be divided into three categories: sensing detection, monitoring system and execution organization. Machine vision belongs to the automatic use equipment of sensing detection. Machine vision system has very high resolution accuracy and processing speed. It can reach or surpass the vision ability of human eyes on many targets. It can process the content that human body cannot perceive through infrared, ultrasound, microwave special sensor imaging and so on. In addition, machine vision system can work uninterruptedly, and has the advantages of objective and quantifiable imaging targets.
Data show that the global machine vision shopping mall was about 4.2 billion US dollars last year, an increase of 10.5% compared with the same period last year. Among them, the United States is the world’s largest machine vision shopping mall, accounting for 50%. China’s machine vision industry started relatively late, but in recent years it has developed rapidly. Last year, the size of shopping malls reached 350 million US dollars, with an increase rate of about 22.2%. The Organization estimates that in the next few years, China’s machine vision industry will maintain a 20% growth rate, far higher than the global average of 8.4%.
From the point of view of product use, machine vision is not only used as a single product in the field of quality detection, but also widely installed in industrial robots, CNC machine tools and other industrial automation products. It belongs to the upstream central link of automation engineering and is widely used in the process of industrial automation.
Last year, our machine vision system was mainly used in the field of electronic production, accounting for about 46%. In addition, 10.9% of cars and 9.7% of pharmaceuticals were used. China’s machine vision skills are becoming more sophisticated, and the scope of future use will gradually expand. The occupational needs of food, packaging, printing, logistics, instrumentation and other industries are expected to significantly improve.
Industrial robots. Machine vision brings good news for obstacle avoidance and navigation of industrial robots. The human eye in the industrial production line can not satisfy the requirements of industrial promotion in terms of accuracy and power. As for the products which can not observe objects and have high precision, only rely on machine vision. With the rapid addition of industrial robotic shopping malls and the continuous improvement of production accuracy, machine vision skills have been successfully used in industrial robots and become a central key skill.
Medical robots. It is estimated that the combined growth rate of global medical robots sales in the next three years is about 55%, and the compound addition rate of surgical robots and recovery robots will reach 30% and 47% in the next five years. It can be seen that both medical robots and industrial robots have huge shopping mall space to wait for excavation, and machine vision adds thrust.
UAV category. Machine vision is the primary problem for UAV to complete unmanned. Analytical think tank believes that the smart UAV will insist on exceeding 50% in the next few years, exceeding 10 billion yuan in 2018. In addition, Tesla and time-sharing lease add new popularity for automatic control, and machine vision benefits.
Security category. Intelligent security is an important part of China’s smart city. Machine vision can accomplish intelligent supervision through biological identification, intelligent event analysis and terahertz skills. It liberates a lot of human resources and greatly improves power, making it possible to climb the sky and see through the eyes.
At that time, machine vision has been successfully used in industrial robots, automatic control, medical diagnosis, security monitoring and industrial testing and other fields. With the emergence of new skills in the science and technology industry, the window of the use of machine vision will be opened. In the future, this use of skills will be extended to consumer electronics, wearable equipment, advanced car control assistant system, intelligent monitoring and other areas closer to the people’s day, as well as the hottest new occupations at that time.
