Paper Abstract

The Naval Biodynamics Laboratory is engaged in a series of experiments to evaluate the dynamic response of critical anatomical segments to acceleration environments. A target configuration attached to a T-plate and affixed to an anatomical segment is acquired by at least two cameras, and linear displacement and orientation components are derived from this data. The quality of these cinematographic solutions depends on the number of targets and on the geometry of the target configuration relative to the camera axis orientation, as well as on errors in camera location and orientation, errors in photo-target location on the T-plate, timing errors between cameras, and high frequency noise errors. This paper presents methods for statistically assessing these errors while obtaining the solution for the kinematic variables and presents plots of these errors for representative runs in the NBDL data base. The possibility of using the method for dynamically eliminating poor quality solutions is also discussed.
