Tips for choosing lens light sources:
-
Contrast: Contrast is crucial for machine vision applications. The primary task of lighting in machine vision is to create significant contrast between features that need to be observed and those that need to be ignored, making it easier to distinguish features. Contrast is defined as having sufficient grayscale difference between features and their surrounding areas. Good lighting should ensure that the features to be detected stand out from the background.
-
Robustness: Robustness refers to the ability to adapt well to the environment. A good LED lighting source should have the same effect in practical work as it does in the laboratory.
-
Brightness: When choosing between two light sources, opt for the brighter one. If the light source is not bright enough, it will inevitably require a larger aperture, reducing depth of field.
-
Uniformity: Uniformity is a critical technical parameter of a light source. A light source with good uniformity ensures stable system operation.
-
Maintainability: Maintainability primarily refers to how easy it is to install and replace the light source.
-
Lifespan and Heat Generation: The brightness of the light source should not decline rapidly, as this can affect system stability and increase maintenance costs. Light sources that generate a lot of heat tend to have faster brightness degradation and shorter lifespans.
