In the field of industrial automation and machine vision, the performance of an imager as a high-precision measuring device depends largely on the industrial camera selected. The right industrial camera not only enhances the measurement accuracy of the imager, but also improves the operational efficiency and stability of the system.

Classification of industrial cameras

1、By chip type

① CCD camera: based on charge-coupled devices, with high image stability and high transmission capacity.

② CMOS camera: based on complementary metal oxide semiconductor, low power consumption, high integration.

2、According to the characteristics of the sensor structure:

① line array camera: suitable for slender field of view or very high precision detection.

② surface array camera: one-time access to the complete image, suitable for area, shape, size and other measurements.

3、According to the output signal mode:

① analog camera: output analog signals, gradually replaced by digital cameras.

② digital camera: output digital signal, easy to computer processing and analysis.

4、According to the resolution:

① ordinary resolution camera: for general precision requirements of the occasion.

② high-resolution cameras: for high-precision requirements of the measurement and detection.

Key Factors in Selecting an Industrial Camera for Imaging Instruments

1. Resolution: Imagers often require high accuracy measurements, so high resolution cameras are preferred. Higher resolution cameras can provide more image details and improve measurement accuracy.

2. Pixel Depth: Pixel depth determines the number of data bits per pixel. High pixel depth provides richer grayscale information, which is especially important for processing and analyzing complex images.

3. Frame rate: Frame rate determines the number of frames per second that the camera collects. For the measurement of high-speed moving objects, a high frame rate camera can capture more dynamic information and improve the accuracy of the measurement.

4. Interface type: Choosing the right interface type (e.g. Camera Link, GigE, USB, etc.) ensures efficient data transfer between the camera and the imager system.

5. Spectral Response Characteristics: According to the different measurement objects, choosing a camera with appropriate spectral response characteristics can ensure the accuracy and stability of image acquisition.
