ESTIMATION OF EES VALUES BY VEHICLE 3-D MODELLING
Journal Title: Mobility and Vehicle Mechanics - Year 2018, Vol 44, Issue 1
Abstract
Energy Equivalent Speed value (EES) is the base of energy method for crash velocity assessment. Estimation of EES value is based on deformation depth and a vehicle stiffness coefficient. Vehicles that are damaged in traffic accidents are usually unavailable for accidents experts so they have to rely on photographs of those vehicles. Development of 3-D photogrammetry and leading software solutions in the field of photogrammetry allowed more detailed overview of deformation on vehicles that were involved in accidents. One of those software solution, that provide 3D models from pictures taken in the planned photo session, is PhotoModeler Scanner. By comparing 3D models of a damaged and undamaged vehicle, experts can get more insight into the type and damage intensity. Analysing those 3D models, information about deformation depth are obtained. This paper shows the procedure of forming a 3D model of an undamaged vehicle created from photographs that were taken in the planned photo session and processed in PhotoModeler Scanner software. This model was compared with a 3D model of the same type of vehicle made from photographs taken at the accident spot. Based on measurements that are taken from those 3D models, the main elements for EES estimation are determined.
