What is the difference between an industrial camera and a normal camera

Machine vision inspection technology has important applications in modern industrial production, and industrial camera is one of the main components of machine vision inspection system, playing a very important role in machine vision inspection system. When it comes to cameras, everyone is familiar, but the price of industrial cameras used in machine vision inspection systems is much higher than that of ordinary cameras. What is the difference between the two? This article will compare in several ways.


  1. Appearance structure

  From the appearance and structure, industrial cameras are compact, not easy to damage, and can work continuously in harsh environments. Ordinary cameras generally have a beautiful appearance and good portability, but they cannot work continuously for more than 24 hours.

  2. Subject

  Taking into account the specificity of the subject, industrial cameras have a short exposure time, so they can capture high-speed moving objects. For example, attach a business card to a fan blade, rotate at maximum speed, set the correct shutter time, and capture images with an industrial camera. You can still clearly distinguish the fonts on the business card. This is obviously impossible for a normal camera that can only shoot 2 to 3 images per second.


  3. Image sensor scanning mode

  In the scanning method of the image sensor, the industrial camera is progressive scanning, and the ordinary camera is often an interlaced scanning or even a three-line scanning. The reason for this difference is that progressive scanning image sensors are difficult to produce, low yield, low shipping costs, and high price. The advantage is that they can clearly capture fast moving objects, but this is not an urgent need for ordinary cameras, so for ordinary cameras. A cross-image sensor may be the best choice.


  4. Constitutive elements

  In terms of composition, the difference between the two is obvious. Industrial cameras pursue the authenticity of acquired images, and image sensors convert optical signals into electrical signals and store or output them directly. Ordinary cameras, such as SLR cameras, have also added a separate image signal processing unit (ISP). The ISP performs linear correction, noise removal, dead pixel repair, color interpolation, white balance correction, exposure correction, etc. through operation processing to enable images to Satisfy the visual perception of the human eye, but this beautification is a taboo for industrial visual inspection. For example, if the image is made from ingredients and the camera is a chef who processes the ingredients, the industrial camera will pursue the taste of the ingredients themselves, while the average camera will add flavor by adding seasonings, while the target of the seasoning is different.


  5. Output image quality

  In terms of output image quality, industrial cameras output bare data, wide spectral range, suitable for high-quality image processing algorithms; ordinary cameras are limited by data storage space, often compress images, and the spectral range is only suitable for human vision.

  The difference between industrial cameras and ordinary cameras is where I believe that everyone has already got a certain understanding.
