<title>A Photographic Data System For Determination Of 3 Dimensional Effects Of Multiaxes Impact Acceleration On Living Humans</title>

Abstract

The Naval Aerospace Medical Research Laboratory Detachment cinephotographic system in use in an investigation of human and human analogue dynamic response to impact acceleration is intended to provide documentary film footage as well as accurate measures of the kinematics of these responses in two and three dimensions. A complete description of this system is undertaken in both its hard and software phases. Accounts of filming and lighting schemes for "G" environments, digitization of photographic data, and a mathematical solution for the position and orientation of a multiply targeted rigid body as acquired by a number of fixed cameras are included in the development.
