1. A method for checking vehicles in a car park, comprising:
- identifying a vehicle by recording images and analysis of the vehicle at an entrance control and at an exit control,storing the analysis results from the entrance control,comparing the analysis results from the exit control with the stored analysis results from the entrance control, andpreventing or allowing the vehicle to leave,wherein at the exit control, the vehicle is driven forward to a front exit barrier, anda rear exit barrier is set up behind the vehicle,the analysis results includes;
identifying, in at least one of the images taken at the entrance control and at least one of the images taken at the exit control, a position of at least one reflector device on the vehicle,identifying a position and orientation of at least one light arrangement on the vehicle via the analysis of the image recording,determining a type of vehicle on a basis of information stored in a database relating to the position and orientation of at least one light arrangement on different types of vehicles and the identification of the position and orientation of the light arrangement, andidentifying a position and orientation of a registration plate of the vehicle in relation to the identified position of the at least one light arrangement via the image analysis of the image in order to thereby obtain a unique identification of the vehicle,the comparing includes comparing the position of the at least one reflector device from the exit control with the stored analysis results from the entrance control, andremoving the front exit barrier only when the vehicle is to be allowed to leave, so that other vehicles are prevented from driving through the exit control at the same time as the vehicle.

Abstract
The invention is provided by means of a method for identifying a vehicle, comprising recording at least a first image of the vehicle using a digital camera, which first image includes at least a registration plate and a light arrangement. The method comprises the steps of identifying the position on the car and the orientation of the light arrangement from the first image, and of determining the type of vehicle on the basis of information stored in a database relating to the position and orientation of light arrangements on different types of car and the identification of the position and orientation of the light arrangement, and of identifying the position on the car and the orientation of the registration plate in relation to the identified position of the light arrangement from the first image in order thereby to obtain a unique identification of the vehicle.

7. A vehicle lock in a car park arranged to allow vehicles to pass through in a secure way from a first area to a second area, comprising:
-
an entry barrier is arranged to prevent entry to the vehicle lock in a first position and to allow entry to the vehicle lock in a second position, the entry barrier being arranged to prevent entry into the vehicle lock when the exit barrier allows exit from the vehicle lock, an exit barrier is arranged to prevent exit from the vehicle lock in a first position and to allow exit from the vehicle lock in a second position, the exit barrier being arranged to prevent exit from the vehicle lock when the entry barrier allows entry into the vehicle lock, and an identification device is provided to identify at least one reflector device on a vehicle, wherein the position and orientation of the reflector device in relation to an identification position of a light arrangement of the vehicle is used to determine if the vehicle is allowed to pass through the vehicle lock. - View Dependent Claims (8, 9, 10)
