Reconstruction of Car Crash Scenes Using a 3D Building and Query Algebra

In this paper, we define a novel 3D building and query algebra for reconstructing car crash scenes. In particular, a low-cost 3D tool based on such algebra is proposed in order to collect and manage the same data set that will be used in the investigation procedures. Once acquired the GPS coordinates of the involved vehicles and scenes details by means of appropriate measurement systems, our tool provides the 3D models of all the scene objects with a set of useful multimedia information and displays them on 3D maps. Preliminary results in the case of a motorway car crash scene are presented and discussed.
