What is the main role of industrial cameras in machine vision systems?

Machine vision uses machines instead of human eyes to make measurements and judgments. It converts the photographed target into an image signal and sends it to the image processing system for various operations to make various judgments. The entire machine vision system is composed of many parts, and the camera plays the role of eyes in the entire vision system, so its importance is very obvious. So, in industrial production, what are the requirements for industrial cameras for a complete machine vision system?

Today, the application of machine vision technology is mainly divided into two sectors: high-end applications and low-end applications. The high-end application sector requires industrial cameras to have high frame rates, high resolution, and high dynamic performance, and the price requirements are not particularly demanding, as long as they are reasonable; while the low-end application sector requires cameras to have good resolution, large discounts in terms of price, and the operation needs to be as simple as possible. From this point of view, high cost performance is the most basic requirement for industrial cameras in machine vision systems.

As we said above, industrial cameras are the core of the machine vision system, and at the same time, they are also the most expensive hardware equipment. At present, foreign industrial cameras are technically more mature than domestic ones, but the corresponding prices are also relatively expensive. Although domestic industrial cameras have not yet fully reached the top international level, their development speed is also very fast. Then, while technology advances, strict price control is the prerequisite for creating a higher cost performance, and it is also the basic capital for domestic industrial cameras to seize the market. For distributors of overall solutions, what they provide to customers is not just cost-effective industrial cameras, but an affordable, stable and high-performance system package.

The main role of industrial cameras in machine vision systems is image collection, and whether the images are captured accurately and clearly plays a key role in later processing and judgment. Therefore, high-performance cameras largely determine the success or failure of system operation. At present, machine vision technology is not only used in the industrial field, but also widely used in scientific research, medical, astronomy and other fields, and the applications of corresponding cameras are also increasing. Progressive analog cameras are often used in traditional industrial applications, but their resolution is not high and the images are not very clear. As the scope of applications expands, in order to adapt to more application requirements, analog cameras are gradually replaced by digital cameras. In fact, this is the advancement of technology. Only with continuous technological progress can my country's industrial cameras meet the pace of my country's accelerating development.
