The design of light source and optical system is an important part of the machine vision system. The core of a machine vision system is image acquisition and processing. All information comes from the image, so the quality of the image itself is critical to the entire machine vision system. The light source is an important factor affecting the image quality. Through appropriate light source lighting design, the target information and background information in the image can be optimally separated, thereby greatly reducing the difficulty of segmentation and identification of image processing algorithms, and improving the positioning and measurement of the system. accuracy, and system reliability. Conversely, if the light source is not properly designed, it will result in less effort in the design of image processing algorithms and imaging systems.

In the machine vision system, the main function of the light source is to illuminate the target, improve the brightness of the target, form an imaging effect that is conducive to image processing, overcome the disturbance of ambient light, and ensure the stability of the image.
Therefore, the design of light source and optical system is an important part of the machine vision system. In the machine vision system, the functions of the light source are at least the following: illuminating the target and improving the brightness of the target; forming an imaging effect that is conducive to image processing; overcoming the disturbance of ambient light and ensuring the stability of the image.
