A Cheap Visual Inspection System for Measuring Dimensions of Brass Gear

Dimensional inspection is one of the main sections of industrial parts production process. Machine vision is a modern method to inspect produced parts. Using machine vision has some problems in measuring parts dimensions and also these solutions are expensive for small industries. In this paper, problems of visual dimensional inspection have been explained and some solutions have been proposed to improve these systems performance. To do this, a visual inspection system has been implemented to control production quality of a brass gear. This system is an accurate, repeatable, fast and cheap solution for small industries. Experimental results show that the system more accurate and repeatable than the manual methods.
