Method and apparatus for mapping a road and accident prevention system

Apparatus and method for mapping a road while driving a vehicle, said two data acquisition modules are arranged on the sides of the vehicle, each of which has a GPS receiver and an antenna, so that the position of the vehicle can be determined, and from which each has a linear camera, the one-dimensional images of an area on the respective side in a vertical plane extending perpendicularly to the road level provides, so that come from a direction perpendicular to the road information on the road perspective. A processor unit forms a cartographic database of the road, where it sets the vehicle position in correlation to the information on the road. stand instead of the cameras, or in addition to the cameras scanning laser radar available that emit perpendicular to the road downward waves and receive reflected waves, from which information about the distance between the laser radar and the bottom are to be derived, which are used in the formation of the database can.
