In the process of intelligent manufacturing, machine vision mainly uses the computer to simulate the human vision function, that is, the image information of objective things to extract, process and understand, and finally used for the actual detection, measurement and control. To realize "Made in China 2025" and complete the transformation from a manufacturing power to a manufacturing power, intelligent manufacturing is the main direction. In the process of intelligent manufacturing, machine vision mainly uses the computer to simulate the human vision function, that is, the image information of objective things to extract, process and understand, and finally used for the actual detection, measurement and control. With the intensification of intelligent manufacturing, the market demand for machine vision will gradually increase.

Machine vision is widely used in life, and plays an important role in the fields of transportation, hydrological observation, geological disaster early warning and identification. On a macro level, the fast-growing sub-industries are face recognition and image recognition. The two branches focus on finance, security and transportation. Most of the investors in these segments have their own technological advantages and will provide application solutions for various scenarios to make profits.

The development status of machine vision in China

China's machine vision industry started late and the concentration is not very high. Originally mainly represented foreign brands. In recent years, many distributors have started to develop their own products, but there is still a certain gap between them and foreign countries in terms of industry distribution, channel distribution and mature automation products. Domestic machine vision relatively mature automation product quality and technical content is low, the market is far from saturation.

Machine vision enterprises can be roughly divided into first-level developers, second-level developers and product agents. Domestic machine vision enterprises are mainly foreign machine vision product agents and system secondary developers. At present, more than 100 foreign brands have entered the Chinese machine vision market, more than 200 local enterprises are responsible for sales agents, and more than 50 professional system integrators. Domestic truly professional machine vision manufacturers are few, but the local machine vision system manufacturers and machine vision system components have some defects.

The development trend of machine vision in China

Visual image technology needs to focus on building four core competencies:

First, intelligent recognition. Rapid convergence of massive information, from the massive information to find the key features. Accuracy and reliability are key.

Second, intelligent measurement. Measurement is the foundation of the industry and requires precision.

Third, intelligent detection. On the basis of measurement, the comprehensive analysis and judgment of multiple information and multiple indicators are carried out, focusing on the intelligent judgment based on complex logic.

Fourth, intelligent interconnection. The massive data of images are collected and interconnected at multiple nodes, and the data of personnel, equipment, production materials, environment and technology are interconnected, generating innovative capabilities such as deep learning, intelligent optimization and intelligent prediction, truly demonstrating the power of Industry 4.0.
