Optical lenses are used in machine vision systems to assist in the detection of machine vision to improve efficiency, enhance effects, improve image analysis clarity, and accuracy. They are an important part of assisting smart devices. It is also an important consideration for machine vision systems.
The visual light source acts as the vanguard in machine vision and is a supplier of upstream components in the machine vision industry chain. The success or failure of light source and spherical/aspherical/cylindrical/paraboloid optical lens design is a key factor in determining the success or failure of the system.
Through proper procurement high efficiency thin-film multilayer optical filter illumination design, the target information and background information in the image can be reasonably separated, which can greatly reduce the difficulty of segmentation and recognition of image processing algorithms, improve the positioning and measurement accuracy of the system, and make the system reliability and comprehensive performance. Improved. Conversely, if the light source is not properly designed, it will result in half the effort in image processing algorithm design and imaging system design. Therefore, the success or failure of the design of the light source and optical system is an important factor in determining the success or failure of the system.
Optical lenses have the following functions:
1. Illuminate the target and increase the target brightness;
2. Forming an imaging effect that is advantageous for image processing;
3. Overcome ambient light interference to ensure image stability;
4. Used as a tool or reference for measurement.
Since there is no universal machine vision lighting device, the corresponding lighting device should be designed for each specific application example to achieve the desired effect.
LED light source main advantage
It can be made into various shapes, sizes and various illumination angles. It can be made into various colors as needed, and the brightness can be adjusted freely. Can be freely designed according to customer needs. Long service life (about 30,000 hours, longer service life), low operating costs, and great advantages in terms of overall cost and performance. Fast response, high brightness in 10 microseconds to faster times. The power supply has an external trigger and can be controlled by a computer.
With the development of artificial intelligence industrialization, the machine vision industry is also developing at a high speed, which is followed by the market layout of customizable large size optical prism manufacturers. According to the market research report, it can be seen that the layout of South China is mostly in Dongguan, Guangdong. East China is mainly Jiangsu, Zhejiang and Shanghai, and North China is mainly Beijing.
