  Industrial cameras have important applications in industrial production, and industrial cameras are also an important component in machine vision systems. When choosing to purchase industrial cameras, there are many industrial camera parameters that need to be judged. So, what are the main parameters of industrial cameras? Here are the TEO Dior industrial camera manufacturers to give you a detailed introduction.

  What are the main parameters of industrial cameras?

  Resolution

  It refers to the pixel distribution on the phase sensitive surface of the camera area array sensor, which directly affects the sharpness of the shooting.


  2. Sensor model

  Mainly CCD and CMOS, these two sensors have their own advantages and disadvantages, but CMOS will be the mainstream of the market.

  3. Noise

  The noise of an industrial camera refers to a signal outside the actual imaging target that is not desired to be acquired during imaging.


  4. Signal to noise ratio

  The signal-to-noise ratio of the camera is defined as the ratio of signal to noise in the image (the ratio of the average gray value of the effective signal to the root mean square of the noise), which represents the quality of the image. The higher the image signal-to-noise ratio, the better the image quality.


  5. Dynamic range

  The dynamic range of the camera indicates the range of the camera's detected optical signal. The dynamic range can be defined by two methods. One is the optical dynamic range, which is the ratio of the maximum light intensity at saturation to the light intensity equivalent to the noise output. Decide. The other is the electronic dynamic range, which refers to the ratio between the saturation voltage and the noise voltage. Dynamic Range = Full Well Capacity of Photosensitive Element / Equivalent Noise Signal Dynamic range can be expressed in terms of multiples, dB or Bit. With a large dynamic range, the camera is more adaptable to different light levels.


  6. Spectral response

  Spectral response is the ability of the chip to respond to light at different wavelengths of light, usually given by the spectral response curve.


  7. Exposure method

  Different industrial cameras have different exposure methods. Line array cameras generally use progressive exposure. Area array cameras generally use frame exposure and scroll line exposure, and some area array cameras use field exposure.

  8. Camera Interface: There are many types of interfaces for industrial cameras, such as Cameralink, Coaxpress and USB3.0. Among them, Coaxpress is superior to other interfaces in data transmission speed.


  9. Maximum frame rate

  This parameter is an important measure of the camera's transmission image rate. For a typical area array camera, the number of frames is collected per second. For most line cameras, the number of lines is collected per second. This is when selecting an industrial camera. An essential parameter to consider.


  10. Cell size: the size of a single pixel, the larger the pixel size, the higher the sensitivity of the camera.

  The main parameters of the industrial camera are those who have introduced Dior. Different fields have different requirements for industrial camera parameters. For example, Dior has many industrial cameras with different parameters in this respect. Dior's products include a full range of industrial cameras, dedicated cameras for industrial image measurement, and more. You can call us if you have any needs in this regard.
