Compared with the new opportunities brought about by the resonance of concepts such as virtual reality, human-computer interaction, robotics, and security, machine vision emulates and replaces not only human eyes but a whole set of vision systems. With powerful information processing capabilities, machine vision can be applied not only to industrial production, but also to the field of artificial intelligence in the future. The imagination space can be expanded.
It is reported that machine vision has the advantages of high efficiency, high precision, strong stability, adaptability to dangerous environments, wide sensitization range and other artificial vision that cannot be compared. With the continuous extension of industrial automation, the machine vision industry has a wide range of applications, experts say, robot vision The application mainly manifests in four aspects: 1. Guide and positioning: The loading and unloading use machine vision to locate and guide the robot arm to accurately grasp. 2. Appearance test: Check whether there is any quality problem on the product line. This link is also the most part to replace the manual. 3, high-precision testing: Some products have high precision, reaching 0.01 ~ 0.02m even to u-level, the human eye can not be detected must use the machine to complete. 4. Identification: The traceability and collection of data are used in automotive parts, food, and pharmaceuticals.
The domestic machine vision industry has entered a period of rapid development since 2009, with an annual growth rate of about 15-20%. The development of machine vision allows the machine to understand the world. With the public's attention to product quality and the deepening of automation reforms, the penetration rate of machine vision in various industries will also gradually increase.
In the era of "intelligence" machine vision has great potential for development
Intelligent transportation, smart homes, smart wearable devices... The era of “smart†era, smart manufacturing will become the direction of future development. In the process of intelligent manufacturing, machine vision mainly uses computers to simulate human visual functions. It has a part of the functions of the human brain. It extracts information from the images of objective things, processes them and understands them, and is finally used for actual detection, measurement, and control. . In the next few years, as China's processing and manufacturing industry develops, the demand for machine vision will gradually increase.
It is understood that the machine vision market started to start in 11 years and began to show explosive growth in 13 years. In 2014, the Chinese market is 8 billion, and in 2015 it is estimated to be 20 billion (including system integration equipment).
With the increase of machine vision products and improvement of technology, the application of domestic machine vision will shift from the low end of the initial stage to the high end. With the involvement of machine vision, automation will move in a smarter and faster direction.
Industry analysis, with the development of machine vision, new industry applications may emerge in the future. The relatively large amount of industrial production may be in the logistics industry, especially when it comes to 3D vision. Civil service may require more experience. The difficulty is that the variability of the environment is large and the redundancy of the algorithm is more demanding. Civil applications will mainly come from consumer-grade products.
Machine vision development encounter threshold
In recent years, China's machine vision has developed to a certain extent, and the future development potential is huge. However, at present, domestic machine vision still encounters certain thresholds in the development process.
Some industry analysts have analyzed that the threshold of machine vision components is mainly reflected in software algorithms. However, there are large gaps in the processing speed and capability of domestic enterprises. At the same time, due to late start of the industry, there are few shipments and there is no hardware price. Advantage.
The author was informed that currently there are nearly a few machine vision product manufacturers in China. Compared with foreign machine vision products, the biggest gap in domestic products is not simply in technology, but also includes branding and intellectual property rights. Domestic machine vision products are mainly represented by foreign brands, which are gradually approaching the road of independent research and development of products and started later.
In the future, the quality of machine vision products cannot be measured by a single factor and should be judged gradually in accordance with the unified international standards. With the gradual opening up of automation in China, the product technology that will lead and gradually become open. Therefore, it is difficult to rely on closed technologies to promote the development of the entire industry. Only the formation of a unified and open standard can enable more manufacturers to develop products on the same platform. This is also the driving force for promoting China's machine vision toward the international level.
