Machine vision is a comprehensive technology that includes image processing, mechanical engineering, control, electric lighting, optical imaging, sensors, analog and digital video technology, and computer hardware and software technology ( image enhancement and analysis algorithms, image cards, I/O cards, etc. ) . A typical machine vision application system includes image capture, a light source system, an image digitization module, a digital image processing module, an intelligent judgment and decision-making module, and a mechanical control and execution module.
The most fundamental advantage of machine vision systems is that they improve production flexibility and automation. Machine vision is often used to replace human vision in hazardous working environments where manual labor is unsuitable or where human vision alone is insufficient. Furthermore, in large-scale, repetitive industrial production processes, machine vision inspection methods can significantly improve production efficiency and automation.
The machine vision industry chain mainly includes the upstream component market, the midstream system integration / complete equipment market, and the downstream application market. The upstream component market mainly includes hardware and software providers such as light sources, lenses, industrial cameras, image acquisition cards, and image processing software; the midstream mainly consists of integrators and complete equipment providers; and the downstream market primarily includes the electronics manufacturing industry (phone frame flatness inspection), automotive (connector pin height 3D inspection), logistics, security, printing and packaging, tobacco, food and beverage, and pharmaceutical industries. It can be said that in the current era of "intelligent manufacturing" centered on high-end equipment manufacturing, the development of machine vision is a crucial component.
In the future, machine vision will bring about a broad and profound transformation in both daily life and manufacturing. With the explosive growth of artificial intelligence, machine vision, as one of the representative technologies, will inevitably become a new growth point for the industry.
