Industrial robot vision systems mainly consist of four categories: pattern recognition, counting, visual positioning, dimensional measurement, and appearance inspection. Applications like autonomous driving and facial recognition can also be categorized under robot vision. To understand the application scope of vision systems, it's essential to first understand the components of domestic machine vision systems.
What are the main components of a robot industrial control system?
1. Light source: The light source is the most crucial component of domestically produced industrial robots. The quality of a light source depends on its contrast, brightness, and sensitivity to changes in position. The machine vision industry primarily uses LED light source products. Currently, the domestic production rate of the light source industry is relatively high, leading to relatively fierce competition.
2. Lenses: Domestic companies have some competitiveness in low-end lenses, but high-end lenses are still largely imported. The basic function of a lens is to modulate light beams and image the target onto the photosensitive surface of an image sensor to complete signal transmission. Different industrial lenses are used in different industrial environments, and their prices vary considerably.
3. Industrial cameras: Industrial cameras are mainly imported from Europe and the United States, but domestic brands have begun to gradually replace imports, starting from the low-end market. Industrial cameras are the core component of industrial vision systems. Their function is to convert light signals into electrical signals, requiring higher transmission power, anti-interference ability, and stable imaging capabilities.
4. Image capture card: Image capture cards are a relatively well-developed and mature technology in my country. Some people also call them video capture cards. This component is usually plugged into a PC. The function of this capture card is to connect the camera to the PC. It acquires data from the camera and converts it into information that the PC can process.
5. Image processing software: Image processing software is basically monopolized by foreign companies, with domestic companies only making some moves in secondary development. Industrial vision software processes digital signals to extract target features, controls the actions of field equipment based on the judgment results, and automatically completes image acquisition, display, storage, and processing.
6. System integration: Domestic manufacturers are developing rapidly in the integration field, especially in areas where foreign capital has not yet established a presence, or in the field of non-standard automation. The profit margin for secondary development by domestic integrators is relatively small. Generally, after completing their downstream layout in a certain industry, they will gradually try to move upstream to the underlying layer, researching import substitution for core software and hardware.
