Abstract:Vehicular accidents are one of the great societal challenges. In some demographics, they are the leading cause of death. It is important that accidents are thoroughly investigated. In this project we use Structure-from-Motion (SfM) techniques to create 3D models of the whole accident and of relevant parts. The investigator only needs to use a standard camera to take pictures of the scene from many locations and perspectives. Given enough images, the SfM software computes a 3D model. We will develop tools to integrate the models into the investigative procedures, e.g. by comparing the model of the damaged car with an intact model to determine the crush. We will also collaborate with Texas A+M Transportation Institute (TTI) to find additional use cases and make it a useful tool in collision research.
