차량 충돌사고 해석을 위한 3차원 스캐닝/모델링 활용

Abstract

This paper proposes effective 3-dimensional collision crash modelling methods using photogrammetry and a 3D scanner, along with the scientific application methods of these models for reconstruction analysis of vehicle collision accidents. Two methods based on photogrammetry are presented: one is by using a small number of pre-existing photos, and the other is by using a large amount of photos taken for the exact purpose of 3-dimensional modelling. With the 3D scanner measurement method, a 3-dimensional collision crash model that is more elaborate than photogrammetry is created. Several application methods for accident reconstruction analysis are proposed based on the modelling process and the characteristics of the results.
