Female Calvaria Shape Digitization: A Method to Create a Database of Scalp Shapes to be Used in Equipment Design
Abstract
At the request of our customer Mr. Mark Richter of the United States Marine Corp/Marine Expeditionary Rifle Squad (USMC/MERS), the United States Air Force (USAF) Anthropometry Laboratory (711 HPW/HP/HPIF) developed a head fixation rig and a method to collect point data, through hair, that could be used to represent the geometry of a scalp. This work was driven by the inadequacy of current head scan data and the confounding effects of hair volume. An improved representation of head geometry, particularly in the form of a large database, will become a much needed resource to improve helmet design. This report details the methodology developed that will be used to conduct scalp shape surveys in order to create a functional database. This methodology includes descriptions of a head fixation rig, the data collection method, and of software that automates the integration of the data collected with the USAF rig and method. This software, developed by the Morphometrics Laboratory at Florida State University (FSU) uses the collected scalp point data to generate a smooth, polygonal mesh head form in proper relation to a 3D scan of each subjects face (Figure 1). The resulting head database will be able to serve as a helmet and helmet mounted equipment (HMDs) design resource.
