System for Use in Stations for Road Tolls
First Claim
1. A system for use in stations for road tolls, comprising:
- a first optical apparatus for recording images of the roadway,a second apparatus for wireless communication with a vehicle apparatus,wherein a height above the roadway and an angle in a lateral and a vertical direction in relation to the roadway are known for the first apparatus,wherein the second apparatus can determine coordinates for the vehicle apparatuses in at least two directions through its communication with the vehicle apparatuses,means for being able to detect one or more number plates from an image taken using the optical apparatus,means for calculating the positions of the detected number plates in three directions,means for being able to determine any associations between number plates and vehicle apparatuses by comparison between the positions of the number plates and the positions of the vehicle apparatuses.

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.

11. A road tolling system, comprising:
-
a first optical apparatus for recording images of the roadway, wherein the first apparatus is at a height above the roadway, is at a lateral angle relative to the roadway, and is at a vertical angle relative to the roadway, a second apparatus for wireless communication with a vehicle apparatus, wherein the second apparatus is to determine coordinates for the vehicle apparatuses in at least two directions through its communication with the vehicle apparatuses, a detector in communication with the first apparatus, the detector to detect one or more plates from an image taken using the optical apparatus, a calculator in communication with the detector and to calculate positions of the detected plates in three directions, and a comparator in communication with the calculator and the second apparatus and to determine any associations between the plates and the vehicle apparatuses by comparison between the positions of the plates and the positions of the vehicle apparatuses. - View Dependent Claims (12, 13, 14, 15)
