According to the invention, traffic conditions can be recorded by means of at least two cameras (2, 3), which are located at a distance (15) from one another on a vehicle (1). The recording zones (11, 12) of said cameras intersect (13), thus enabling at least one reference point (R) of the environment and/or identification point of at least one second vehicle to be triangulated (T), e.g. by photogrammetry. After an accident, the behaviour of one or more vehicles (1) can be reconstructed. In addition to the respective spatial position, the three-dimensional, synchronised recording enables the speed, speed direction, changes in direction, acceleration and braking manoeuvres and the self-rotation of the individual vehicles about their centre of gravity to be identified and measured to scale, without requiring a plurality of sensors to be provided on the vehicles. The vehicles (1) can also be projected into a 3D image of the environment to calculate and reproduce a virtual representation from any spectator's perspective. |
