In machine vision projects due to the extensive image processing techniques and many activities can be done in this area, it has caused that in these projects and operations On samples which have been selected for processing, lighting Research and projects would be done in less, while with process of doing a good or excellent lighting depending on type of outgoing projects can reduce the volume of processing of later stages. In this respect Subject of lighting techniques and the products which are in this working field So we'll see how far a good exposure processing can improve the efficiency of a machine vision system.
