Machine Vision Technology Push Industrial Automation Development

- Jan 07, 2019-

Background: With the development of industry and the arrival of industry 4.0 era, machine intelligence is becoming a reality. In particular, the recent development of machine vision technology in industrial automation and the continuous updating and iteration of visual technology make its position in intelligent manufacturing increasingly prominent and promote industrial automation and artificial intelligence. Advances in industries such as intelligent manufacturing have brought stronger momentum to development in all fields.


The development of machine vision history:

Machine vision has been developed for more than 20 years. It is essentially an important branch of computer science. In the 1950s, a simple statistical pattern recognition of two-dimensional images was studied, and in the 1960s, 3D machine vision was studied. From the mid-1970s to the early 1980s, machine vision began to be studied on a global scale. At the same time, MIT artificial intelligence laboratory started the course of "machine vision", and machine vision developed vigorously in this period. 

The vision technology we adopt now belongs to the third generation robot vision system. It adopts high speed image chip processing algorithm, has extremely high intelligence and adaptability, can simulate the human visual function.

Machine vision has three main parts: 

1. Robot eyeball structure robot eyeball is equivalent to camera or scanner. It emits infrared light through the infrared emitter. Infrared light is reflected back when it encounters an object. After receiving the reflected infrared light, the infrared receiver transmits the electric signal to the chip. 

2. As one of the core components of industrial robot, motion control system has a decisive effect on the performance of robot. Its motion control is a branch of automation. Using servo mechanism to drive, such as hydraulic pump, to control the position and speed of the machine by linear execution or motor, with the improvement of robot technology, the precision and speed of robot have been very accurate. 

3. The image itself can only find the desired features after image processing to further perform other command actions, such as the movement of the robot arm and the movement of the robot arm. Enables the robot to complete related commands. 

In the application of industry, it is mainly used in industrial robot production, assembly, handling and other work.


Conclusion: Chinese intelligent manufacturing 2025 and machine vision will be inseparable. In the future, machine vision technology will become one of the core of industrial automation and intelligence. In order to realize the extension of man-machine vision on robot, it is necessary to meet the conditions of high degree of automation, high efficiency, high precision and poor adaptability, and play an important role in the process of industrial automation.
