Three Dimensional Computerized Photogrammetry and its Application to Accident Reconstruction

This paper contains a brief history of the science of photogrammetry followed by the general equations governing the three-dimensional photogrammetric process and it's application to accident reconstruction. Several case studies are presented to illustrate the approach using two photographs. Specifically, these case studies address car crush determination, post-impact articulation angle of a tractor-trailer, and the determination of vehicle post-impact rest locations. In addition to these case histories, the applicability of the three-dimensional process to numerous other accident reconstruction problems is be discussed.
