What is an industrial camera?

Abstract: industrial camera is a key component in machine vision system, and its most essential function is to convert optical signals into orderly electrical signals. Compared with ordinary cameras, industrial cameras have the advantages of strong performance, capturing high-speed moving objects and high frame rate, and are mainly used in industrial and sports fields. Here's an introduction to industrial cameras. 1. What is an industrial camera?

Industrial camera (commonly known as industrial camera) is an important part of machine vision system and plays a very important role in machine vision system. Compared with the traditional video camera, it has the advantages of high stability, strong transmission ability and strong anti-interference ability.

Second, the advantages of industrial cameras

1, industrial fields, such as the development of metal materials and resin materials, can be used to observe the direction and state of internal cracks when materials are impacted, and can be used to analyze the structure when materials are destroyed.

2. In sports, such as baseball and golf, capture the state of the ball and its resistance to the air.

3. In the printing process of packaging and label industry, very subtle printing defects in high-speed printing can be detected in real time. Finding printing defects can provide valuable information for production, so as to take measures in the production process and reduce the final loss. Common defects in printing, such as scratches, dust, missed printing, ink marks and wrinkles, can be easily detected. Not only improve the return on investment and reduce waste, but also improve customer satisfaction and trust.

4. In developing and verifying products, digital industrial cameras have no restrictions on the size of the subject. According to the conditions of the lens, they can be used to shoot general substances and also for microscope photography.

Third, the difference between industrial cameras and ordinary cameras

1, industrial camera has strong performance, stability and reliability, convenient installation, compact and firm structure, long continuous working time, and can be used in harsh environment, which ordinary digital cameras can't do. For example, civil digital cameras can't work continuously for a long time, can't continuous shooting quickly, and can't be fixed on the machine without mounting holes.

2. The shutter time of industrial cameras is very short, which can capture fast moving objects. For example, if you stick a business card on the fan blade, rotate it at the maximum speed, set the appropriate shutter time, and take an image with an industrial camera, you can still clearly recognize the font on the business card. It is impossible to achieve the same effect by taking snapshots with ordinary cameras.

3. The image sensor of industrial camera scans line by line, while the image sensor of civil camera scans every other line or even every three lines. The production process of progressive scanning image sensor is complex, with low yield and less shipment. Only a few companies in the world can provide such products, such as Dalsa and Sony, and they are expensive.

4. The frame rate of industrial cameras is much higher than that of ordinary cameras. Depending on the resolution of the camera, you can take several to hundreds or even thousands of photos per second, while civilian cameras can only take a few photos, which is very different.

5. Industrial cameras usually output rawdata, and its spectral range is often very wide, which is more suitable for high-quality image processing algorithms, such as machine vision applications. However, the spectral range of pictures taken by ordinary cameras is only suitable for human vision, and the quality of compressed images is poor, which is not conducive to analysis and processing.

6. Industrial cameras are more expensive than ordinary cameras. Mainly determined by the market demand. The shipment of industrial cameras is far less than that of civilian cameras, so it is inevitable that the cost will remain high.
