Abstract
This paper presents a method of determining a vehicle crush and equivalent barrier speed (EBS) using digital photogrammetry. A state-of-the-art documentation technique called close-range photogrammetry allows engineers and accident reconstructionists to create three-dimensional (3-D) computer models of damaged vehicles utilizing photographs. Utilizing photogrammetric software, engineers can digitize accident scene photographs to create accurate 3-D computer models of the vehicles, which can be used to quantify structural damage sustained by the vehicles. Crush deformation can be quantified utilizing this process, and the resulting crush dimensions can be input into engineering software to determine a vehicle's EBS. (A)
