Background
Industrial cameras are a key component in machine vision systems, and their most essential function is to convert light signals into ordered electrical signals. The selection of a proper camera is also an important link in the design of a machine vision system, and the selection of the camera not only directly determines the resolution, image quality and the like of the acquired image, but also is directly related to the operation mode of the whole system. Industrial cameras are generally installed on machine pipelines to replace human eyes for measurement and judgment, digital images are taken and the images are converted into image signals, the image signals are transmitted to a special image processing system, the image system performs various operations on the signals to extract the characteristics of the targets, and then the field equipment action is controlled according to the judgment result.
Compared with the traditional civil camera (video camera), the camera has high image stability, high transmission capability, high anti-interference capability and the like, and most of the industrial cameras in the market are cameras based on CCD (Charge Coupled Device) or CMOS (Complementary Metal Oxide Semiconductor) chips.

The photoelectric conversion, charge storage, charge transfer and signal reading are integrated into a whole, and the photoelectric conversion, charge storage, charge transfer and signal reading are typical solid-state imaging devices. The outstanding feature of a CCD is that charge is used as a signal, while the other devices are current or voltage signals. Such an imaging device forms a charge packet by photoelectric conversion, and then transfers and amplifies an output image signal under the action of a drive pulse. A typical CCD camera consists of an optical lens, a timing and synchronization signal generator, a vertical driver, and an analog/digital signal processing circuit. As a functional device, compared with a vacuum tube, the CCD has the advantages of no burn, no lag, low-voltage operation, low power consumption and the like.
The CMOS image sensor integrates the photosensitive element array, the image signal amplifier, the signal reading circuit, the analog-to-digital conversion circuit, the image signal processor and the controller on one chip, and also has the advantage of programming random access of local pixels. CMOS image sensors are widely used in high resolution and high speed applications due to their good integration, low power consumption, high speed transmission, wide dynamic range, and other features.

By selecting a proper light source and a correct lighting mode, the defect area information and the background information in the image can be obviously separated, the difficulty of an image processing algorithm is greatly reduced, and the precision and the reliability of the system are improved. However, there is no universal light source detection device, and a suitable light source needs to be selected for different detection objects to achieve the best effect.
