Machine Vision Light Source Overview
The role of machine vision light sources and their importance in the field of machine vision.
Function:
The most important task of machine vision illumination is to create the maximum contrast between the features that need to be observed and the image features that need to be ignored, thus facilitating the differentiation of features.
Importance:
- Determine the success or failure of the entire system
- Improve the accuracy and efficiency of the system
- Reduce system complexity and requirements for image processing algorithms
