Abstract
As part of the effort to support the L1939 Soldier's Helmet project, and future helmet/equipment design and integration projects, the Defence and Civil Institute of Environmental Medicine (DCIEM) acquired a 3D Cyberware 3030 Laser Scanning System and associated software. The project was undertaken to evaluate the capabilities and limitations of the Cyberware Laser Scanning system and related software, in the context of helmet accommodation. Helmet accommodation refers to the extent to which a helmet design maintains a minimum stand-off distance between the head and interior helmet surface. This minimum stand-off distance is necessary to accommodate helmet shell movement and backface deformation during a ballistic impact. To evaluate the three dimensional laser scanning and imaging system, three dimensional head images, representative of the distribution of head sizes in the Canadian Forces (CF), and images of select helmets and headware equipment were scanned and stored in a computer database. This database, and the associated image manipulation and analysis software, was used to evaluate different helmet designs for sizing assessment based on stand-off distance across the range of CF head sizes. Several helmet accommodation analyses were undertaken to assess the suitability of using a laser scanning method for evaluating helmet stand-off and subsequent shell sizing and shape. TRUNCATED
