Evaluation of 3D Scanners to Develop Virtual Reality Applications

Abstract

The main purpose of this paper is to show the results obtained with the evaluation of 3D (three dimensional) scanners to obtain 3D models or objects which can be used to build virtual reality systems. Firstly, some basic concepts related to this emerging technology are briefly described. Furthermore an evaluation methodology based on MCDM (multi criteria decision making) concepts is applied. The methodology helps decision makers to select the best 3D scanner, based on several criteria and comparing the results obtained applying three different MCDM methods. Finally the results obtained in the evaluation of several scanners are presented.
