A Review on the Usability of Mobile Phone-based Close-Range Photogrammetry, Terrestrial Laser Scanning and UAVs in Traffic Accident Modeling

Abstract

Fast, detailed and accurate three-dimensional (3D) documentation of traffic accident scenes are crucial since it provides data for traffic accident reconstruction which allows determining the vehicle speed, examining the nature of the collision, and affording evidence in court cases. There are various documentation techniques such as classical drawing techniques, photogrammetry, laser scanning etc. The modern methods have become more preferable compared with the classical drawing methods along with the developing technology. In this aspect, 3D models emerge as a solution for fast and detailed documentation of traffic accidents. In addition, deformations can be determined more accurately by using these models in comparison with the classical methods. In this study, three different models were produced by using mobile phone-based photogrammetry, UAV photogrammetry and terrestrial laser scanning. Then, each model was examined comparatively in terms of completeness, visual representation, time efficiency and metric accuracy. In addition, the usability of mobile-phones as a fast and low-cost tool for 3D modeling was also examined in terms of incident modeling.
