1) Contrast contrast is very important for machine vision. The important task of lighting for machine vision applications is to generate a large contrast between the features that need to be observed and the image features that need to be ignored, so that it is easy to distinguish features. Contrast is defined as a sufficient gray measure difference between a feature and the area around it. Good lighting should ensure that the features to be detected stand out from other backgrounds.
2) Robustness
Robustness is a good adaptation to the environment. A good LED lighting source needs to have the same effect as it does in the laboratory.
3) Brightness
When choosing between two light sources, the choice is to choose the brighter one. If the brightness of the light source is not enough, it is necessary to increase the aperture, thereby reducing the depth of field.
4) Uniformity
Uniformity is a very important technical parameter of light source. The light source with good uniformity makes the system work stably.
5) Maintainability
Maintainability mainly means that the light source is easy to install and easy to replace.
6) Life and calorific value
The brightness of the light source is not easy to decay too quickly, which will affect the stability of the system and increase the cost of maintenance. The brightness of lamps with large heat generation decays quickly, and the life of the light source will also be greatly affected.
