First, the technical characteristics of the era of Industry 4.0-vision and image technology are the core (from "smart eyes" to "smart people").

Vision and image technology is one of the great technologies of mankind in the 20th century. 80% of people's perception of outside information is obtained through the eyes, and the amount of information contained in images is huge. In the information age, especially in the industrial information age, visual image technology is destined to become a leader.

Vision technology has improved the ability to obtain information in industrial automation. Information will no longer be simple data in a single dimension, but a wide range of three-dimensional mass data. At the same time, it will greatly break through the limitations of the human eye in dimensions such as speed, size, and spectrum. For example, the vision system basically covers the full spectrum, the resolution can reach 1 micron, and the speed can reach hundreds of millions of frames per second. This greatly exceeds the current level of industrial manufacturing in terms of speed and accuracy, and even meets a more precise, Higher-speed manufacturing requirements can fully guarantee the fast and accurate information acquisition in industrial manufacturing. On the other hand, the rapid development of image technology has enabled massive amounts of image information to be analyzed and utilized at a high speed, in real time, and intelligently, which has greatly improved the speed of human judgments, is getting closer and closer to human intelligence, and hastened the speed of information processing in industrial production And accurate.

The combination of vision and image technology is to install a pair of super "smart eyes" for industrial equipment.

In the future, industrial production will be centered on "smart eyes" and equipped on tens of thousands of various devices to direct a variety of "hand, foot, and body" actions to achieve "depth perception, intelligent decision-making, and automatic execution" ", Become" smart people ", let the automation of intelligent industrial manufacturing soar!

Second, the technical framework of vision technology service Industry 4.0-four intelligent (intelligent identification, intelligent measurement, intelligent detection, intelligent interconnection).

What technologies will visual images develop and how will they change our industry? Let's imagine the future production.

In an electronic product production workshop, the size of various chips and components has been reduced from a few mm to several tens mm to several micrometers to tens of micrometers. The welding and assembly of components is guided by a vision system by a production robot such as Surgery-like precision operations, because the size and quality of the device have been reduced by hundreds of times, the assembly speed has been greatly improved, hundreds of actions can be completed per second, and the production efficiency has been increased by a hundred times. One contains thousands of components. Electronic products can be manufactured in as little as 10 seconds.

The vision system uses 10 imaging units to work simultaneously to achieve multi-angle stereo imaging, a combination of large-scale millimeter-level imaging and ultra-precision micron-level imaging. The speed of each imaging unit reaches more than 1,000 frames per second, and the entire system simultaneously acquires The image information of more than 10,000 frames per second can be processed in real time and comprehensively complete target positioning, accurate measurement, and precise motion instructions.

At the same time, the other 10 imaging units immediately scanned the product at multiple angles and dimensions to confirm whether the quality was up to standard. Suddenly, there is a problem with a solder joint of a certain product. The qualified soldering area is 2 micrometers, and actually only reaches 0.85 micrometers. This will cause the impedance of signal transmission to increase and the working frequency will not reach the normal range. The vision system will immediately guide Inspect the robot and remove the waste to the branch for repair.

More than 500 imaging units in the assembly workshop monitor various environmental indicators, and integrate all image data and other data to the central information server. After analysis, at the instant of the deviation of the solder joints, a total of 5 abnormalities were found, including a slight drive current. Fluctuations, small movements at a time ... The problem was found, image analysis and historical data analysis found that the lubrication of one of the joints was close to the maintenance life, and automatic compensation lubrication was immediately performed. The hidden trouble was eliminated, and the system was running as fast as usual ...

The above scenes are far from covering all of Industry 4.0, but we can see it in the tube. Facing these requirements, visual image technology needs to focus on building four core capabilities.

First, intelligent identification. The purpose of identification is to find the target for the next operation. To identify key features from a large amount of information, target recognition needs to rapidly converge massive information. Its intelligence is high, and accuracy and reliability are key.

Second, smart measurement. Measurement is the foundation of industry. There is no product without measurement. The accuracy of measurement depends on the level of effort.

Third, intelligent detection. The detection is done on the basis of measurement. According to the degree of deviation between the measurement result and the target, it is judged as pass or fail. However, detection is often not a comparison of the results of a single indicator, and comprehensive analysis and judgment of multiple information and multiple indicators are required. Intelligent judgment based on complex logic is the key.

Fourth, smart interconnection. "The future is a world of data", and the interconnection of data will generate endless creativity. Just like human brain neurons, when information and nodes exceed a certain number, they can produce autonomous learning and independent creativity. Creativity is wisdom and creativity is the source of development. When massive amounts of image data are collected and interconnected at multiple nodes, and at the same time data such as personnel, equipment, production materials, environment, and processes are interconnected, innovative capabilities such as deep learning, intelligent optimization, and intelligent prediction are derived, showing the big data Charm will show the true power of Industry 4.0.

The development of hardware, software, and integrated technology for the vision and industry of the future industry will enter an era of continuous upgrading of goals, technical excellence, and continuous innovation! It is time for Chinese companies engaged in machine vision to work hard to develop core capabilities and strengthen innovation. At the same time, they will vigorously cooperate with automation equipment manufacturers and robot manufacturers to "implant eyes and brains for machines." The banner of upgrading the manufacturing industry!

Third, the choice of the times, the fortune of the industry, the fortune of China!

The biggest beneficiary of the concept of Industry 4.0 is China. It seems that the Chinese manufacturing industry, which has tasted the sweetness in the labor-intensive era and is not sensitive to the threats, is arrogant. Developing manufacturing is China's national strategy. "Made in China 2025" has clearly demonstrated the government's enthusiasm and determination. Once launched, it will change the situation at a high speed, and our industry will also move to a new height.

The machine vision industry focuses on the service industry. In the past many years of development, the scale has always been too small. R & D is mostly based on projects and large-scale application of product development is rare. This is far from the climate. This is also due to the low level of automation in our manufacturing industry and the weak driving force for self-innovation.

However, the pioneers of China's machine vision actively expanded in a relatively small space, accumulating energy, and accumulated a considerable number of talents, technologies and management experience. For example, high-end technologies such as imaging and lighting, software algorithms and other countries are basically the same or have a small gap, Some products even surpass similar foreign counterparts in terms of performance and technological innovation. Although there are shortcomings in productization such as reliability and ease of use, the gap is not large. At present, the changes in China's manufacturing industry will definitely ignite the rapid development of the visual image industry. China's machine vision must also shoulder this historical mission and help China's industrial manufacturing industry to transform and upgrade.

Vision and image technology are important cores of Industry 4.0. Mutual promotion of development is the inevitable technology, and it is also the choice of the times. China ’s visual industry has been developing for 30 years, and historical opportunities must not be missed. No longer is it necessary to sigh. What we need is to act quickly, bring forth vigorous talents, show strong innovation, and discuss heroes in the tide of the times!
