Comparison between 3D laser scanning and computed tomography on the modelling of head surface
Publication . Sousa, E.; Vieira, L.; Costa, D. M. S.; Costa, D. C.; Parafita, R.; Loja, Amélia
The measurement of people physical parameters and proportions constitutes an importante field of science, the anthropometry, since it is related to the characterization of the human size and constitution; it allows improving the design and sizing of systems and devices to human use. To enable these measurements, different direct and indirect methodologies may be used depending on the particular aim of a specific study and on the eventual availability of data sources that can be used also for this purpose. Because of this relevance, the present work intends to assess the influence of diferente acquisition and reconstruction methods in the modelling of a 3D head surface. In order to assess the significance of the differences between acquisition and reconstruction methods a set of measurements between several anatomic references of a physical phantom were carried out. Statistical evaluation using the Friedman test for non-parametrical pared samples was considered. We found, so far, no statistically significant differences between the several methods considered for acquisition and reconstruction.
