Abstract: A road calibration system and a method for calibration of a road surveillance system are provided. The road surveillance system monitors a surveillance area of a road using vehicle surveillance devices. The vehicle surveillance devices measure a position of a vehicle passing the surveillance area and are synchronized with a global timing signal. In order to calibrate the vehicle surveillance devices such that a position determination of the vehicle surveillance devices is equal, a calibration vehicle with predefined calibration markers is passed through the surveillance area. During the passage each measurement device measures a position of an assigned calibration marker at a predetermined time and compares a measured distance between the positions of the calibration markers with a reference distance between the positions of the calibration markers.

Abstract: A road calibration system and a method for calibration of a road surveillance system are disclosed. Said road surveillance system is adapted to monitor a surveillance area of a road and comprises a plurality of vehicle surveillance means. Said plurality of vehicle surveillance means are adapted to measure a position of a vehicle passing said surveillance area and are synchronized with a global timing signal. The method comprises, in order to calibrate said plurality of vehicle surveillance means such that a position determination of said plurality of vehicle surveillance means is equal, passing a calibration vehicle with a plurality of predefined calibration markers through said surveillance area. During the passage each measurement means measures a position of an assigned calibration marker at a predetermined time and compares a measured distance between the positions of said calibration markers with a reference distance between the positions of said calibration markers.

Abstract: A method and a device for image registration of the external characteristics and the number plate of a vehicle in a road toll unit for checking the payment status relating to a toll fee, which is intended to be collected by means of remote communication. During the checking and payment operation, the vehicle is followed by successive video recordings. In these recordings, a marker is connected to the vehicle. The same marker is connected to the image of the number plate and to an image of the physical shape of the vehicle. In the event of incorrect payment, a search may be performed based upon both the image of the number plate and the associated image of the physical shape of the vehicle, which are connected together by means of the successive following of the position of the vehicle.
