The visual system of industrial robots is mainly composed of four categories: pattern recognition, counting, visual positioning, scale measurement and appearance detection, such as unmanned driving, face recognition, etc., which can be classified as the field of robot vision. If you want to know the scale of use of the vision system, you must first understand the components of the domestic machine vision system.
1. Light source
The light source is the most abundant link of domestic industrial robots. The quality of the light source lies in the contrast, brightness and sensitivity to position changes, and the machine vision profession first uses LED light source products. At present, the degree of localization of the light source profession is relatively high, and the competition is relatively fierce.
2. Lens
Low-end lenses domestic enterprises have a certain degree of competitiveness, and high-end lenses are basically still relying on imports. The basic function of the lens is to realize beam modulation, and the signal transmission is completed by imaging the image on the light-sensitive surface of the picture sensor. Different industrial lenses are used in different industrial sites according to requirements, and the price gap is relatively large.
3. Industrial camera
Industrial cameras are mainly imported from Europe and the United States, and domestic * has begun to gradually import substitution from the low-end market. The industrial camera is the central component of the industrial vision system, and its function is to complete the process of converting optical signals into electrical signals, requiring higher transmission power, anti-interference force and stable imaging ability.
4. Drawing capture card
The picture capture card is a relatively complete and mature development in China, and some people call it a video capture card, which is usually a card inserted into a PC. The purpose of this capture card is to connect the camera to the PC. It takes data from the camera and converts it into information that can be processed by a PC.
5. Picture processing software
Picture processing software is basically monopolized by foreign companies, and domestic companies only have a layout in secondary development. The industrial vision software calculates the digital signal to extract the policy features, controls the actions of the field equipment according to the results of the discrimination, and actively completes the collection, display, storage and processing of the picture.
6. System integration
Domestic manufacturers are developing rapidly at the integration end, especially in some fields where foreign capital has not yet been deployed, or in the field of non-standard automation. Domestic integration manufacturers carry out secondary development with little profit space, generally after a certain occupation downstream completes the layout, will test the gradual development of the upstream bottom, and discuss the import substitution of central software and hardware.
