The Comparison of 3D and 2D Measurement Techniques Used for the Analysis of Vehicle Deformation

Abstract

As one of the main assumptions for the accident analysis has been detailed information about vehicle deformation. The precise deformation depth allows to quantify deformation energy and related impact speed. The aim of this paper has been the comparison of two selected methods used for the determination of deformation depth. For the purpose of this paper were selected top-view photography as basic and cheap method and 3D scanning as modern and advanced method. Different vehicles and 2 basic types of damage - frontal and side impact - were chosen for the analysis. Also, the different range of vehicle deformation depth were selected. On the basis of obtained results is possible to determine the applicability of these methods, their advantages and limitations.As one of the main assumptions for the accident analysis has been detailed information about vehicle deformation.
