Generating a 3D Simulation of a Car Accident from a Written Description in Natural Language : the CarSim System

Abstract

This paper describes a prototype system to visualize and animate 3D scenes from car accident reports, written in French. The problem of generating such a 3D simulation can be divided into two sub-tasks: the linguistic analysis and the virtual scene generation. As a means of communication between these two modules, we first designed a template formalism to represent a written accident report. The CarSim system first processes written reports, gathers relevant information, and converts it into a for mal description. Then, it creates the corresponding 3D scene and animates the vehicles.
