What should I pay attention to when selecting an industrial camera

  Industrial cameras are a key component in machine vision systems, and their most essential function is to convert optical signals into ordered electrical signals. Choosing the right camera is also an important part of the design of the machine vision system. The choice of the camera not only directly determines the image resolution, image quality, etc., but also directly relates to the operating mode of the whole system. So, what do you need to pay attention to when selecting industrial cameras? Let's take a look at Dior Xiaobian.

  1. Resolution: The number of pixels (Pixels) of the image captured by the camera at each time is generally directly related to the number of pixels of the photoelectric sensor for the digital camera, and depends on the video system for the analog camera.

  2. Pixel Depth: The number of bits per pixel of data.


  3, Frame Rate / Line Rate: The rate at which the camera captures the transmitted image. For area array cameras, the number of frames collected per second (Frames/Sec.) is collected for line array cameras. The number of lines (Lines/Sec.).


  4. Exposure mode and shutter speed (Shutter): For line array cameras, they are progressive exposure mode. You can select the fixed line frequency and external trigger synchronization mode. The exposure time can be consistent with the line period, or you can set Set a fixed time; area array cameras have several common methods such as frame exposure, field exposure and scroll line exposure. Digital cameras generally provide external trigger capture...


  5. Sensor type: CCD type or CMOS camera?

  If the object to be photographed is moving, and the object to be processed is also an object moving in real time, then of course the camera with the CCD chip is most suitable. However, some manufacturers' CMOS cameras can also be used as CCDs if they use frame exposure.

  6. Color: color camera or black and white camera?

  In general, if you want to deal with the color of the image, it is naturally a color camera, if you don't need it, you can use a black and white camera. Because of the same resolution of the camera, black precision is better than color, especially when looking at the edges of the image, black and white will be better.


  7. Transmission interface: What interface is better?

  For the detection accuracy is very high, the resolution of the area array camera does not meet the requirements, of course, the line camera is an inevitable choice.


  What kind of attention should be paid to the selection of industrial cameras? I believe everyone has already got a certain understanding here. If you want to know more about the selection of industrial cameras, you can consult on the official website of Dior Technology. Dior Technology has various types of industrial camera models. It has IEC International Electrotechnical Commission TC79 Safety and Protection Technology Branch Chinese experts, SAC/TC100 National Security and Alarm System Standardization Technical Committee, International Standardization Technical Experts, and China Security Industry Association First and Second. The 3rd governing unit, the standing director unit of Shenzhen Safety and Protection Industry Association, and the Shenzhen Robot Industry Alliance unit.
