Optical 3D Measuring In the Quality Control Of Sheet Metal Products



Goals of the project

This project is a part of a bigger project called Levytuotteiden laadunvalvonta (Quality control of Sheet Metal Products). The goal of this subproject is to find out the possibilities to use machine vision and 3D measurement methods to detect the defects in sheet metal production. Limitations of different techniques and some measurement devices will be examined, too.
