Abstract
The invention relates to a system for use with stations for road tolls, comprising a first optical apparatus for recording images of the roadway and a second apparatus for wireless communication with a vehicle apparatus. The height above the roadway and the angle in a lateral and a vertical direction in relation to the roadway are known for the first apparatus, and the second apparatus can determine coordinates for the vehicle apparatuses in at least two directions through its communication with the vehicle apparatuses. The system comprises means for being able to detect one or more number plates from an image taken using the optical apparatus, and means for calculating the positions of the detected number plates in three directions, and means for being able to determine any associations between number plates and vehicle apparatuses by comparison between the said positions of the number plates and the said positions of the vehicle apparatuses.
