Abstract
In this paper the results are presented of an experiment to evaluate the accuracy of digital photogrammetry with PhotoModeler as a measurement technique and to determine if the technique is suitable for measuring the typical depths of crush found in low speed collisions.
The results of a photogrammetric study of a staged T-style 30-mph collision are also presented. The vehicles involved were photographed, modelled in PhotoModeler, and the pre-impact speed was then found using the crush measurements from the models and empirical equations developed by Dr. D. P. Wood, which relate crush and energy absorbed.
