Craniofacial Anthropometry : the comparison of accuracy between laser scanning and photogrammetry techniques

Abstract

Modelling and measuring of human face are increasingly becoming important for various purposes. One of the purposes is craniofacial anthropometry or human face measurement. Recent innovations in technology have generated a variety of techniques that can be used for craniofacial anthropometry purposes. In this paper, the accuracy of two different techniques was evaluated and compared between each others. The two techniques used in this paper were laser scanning and photogrammetric. Mannequin is the type of data used in this study. The mannequin was scanned using two laser scanners VIVID910 to create the 3D model. Then the measurement was made on the 3D model based on anthropometric landmarks. For photogrammetric technique, Sony Cybershot DSC F828 camera was used with AUSTRALIS software to make the measurements based on anthropometric landmarks. The results from both techniques then were evaluated and compared. From this study, we indicate that the measurement differences for both techniques are less than 1mm.
