Analysis of Light Source Selection and Lighting Technology in Machine Vision

With the development of the technology, more and more application based on machine vision was used in actual production. The selection of light source and lighting method is the key step in the application of machine vision, which directly affects the quality of imaging and the difficulty of subsequent visual processing. Therefore, it is very important to select the proper light source and lighting method. The selection of common light source and lighting method are discussed in this paper.
