Abstract: Parallel axis stereophotography has been applied to record events of an automotive crash simulation. Two 16mm, high frame rate, high acceleration cameras were used of the type developed for use on board military aircraft. The cameras travelled with the crashing vehicle, and were mounted on a rigid frame which was in turn attached to the floor pan of the vehicle. The crashes referred to here simulated car-to-pole side impacts. The cameras provided a stereoscopic record of events within the body shell|s interior during the impact. Displacements and velocities of the anthropomorphic dummies seated in the body shell and of the intrusion caused by the pole, were determined using a single stereo photogrammetric method. Depth measurements were obtained with relative errors of about 1% or 15mm.
Keywords: vehicle design; parallel-axis stereophotography; crash simulation; photogrammetry; anthropomorphic dummies; vehicle safety; car-to-pole side impact.
