Three-dimensional technologies and high-tech methods are gaining more and more importance in accident and crime investigations. Radiological imaging and three dimensional surface scanning deliver highly precise three dimensional data of accident victims and damaged vehicles. Based on these digital data computer-assisted, drawn-to-scale analysis of the injuries of the body and damages to the vehicle allow for the reconstruction of the course of accident. In the present work a collision between a car and a cyclist was analysed with the described methods. The body of the accident victim was scanned with MSCT and three dimensional optical surface scanning. The accident car and the bicycle were also digitised with the surface scanner.The accident scene was documented by the use of a three dimensional laser scanner and photogrammetry. With real data based reconstruction the collision position of the vehicles and the course of the accident could be determined. Furthermore, an external institution used the collected data to estimate the velocity of the car at time of collision. For the covering abstract see ITRD E144229.
