Abstract: A variety of algorithmic approaches such as Finite Element Modeling (FEM) and Surface Modeling (SM) use post-accident photos and other data to reconstruct an accident to improve vehicle damage and occupant injury determination. A database of vehicle models created with these techniques may then be used to create vehicle accident simulations and reconstruct the accident based on different impact and occupant parameters. Accident reconstruction using FEM and other techniques allows accident visualization for Auto Physical Damage (APD) corresponding to the vehicle's insurance policy, internal and external component damage prediction for the vehicle, and occupant injury prediction based on movement during the accident.
