Abstract: The invention is directed to a method and an arrangement for detecting a traffic violation in a traffic light zone through rear end measurement by a FMCW radar device. For this purpose, a vehicle driving through a radar beam of a FMCW radar device, whose first outer edge beam horizontally forms an obtuse angle with the roadway edge, is measured at its front end, flank and rear end. The vehicle length is determined from the obtained measurement signals and added to the specific radial distance of the vehicle, which is determined close to a stop line through the vehicle rear, and a prediction is made based on the vehicle speed about the vehicle front driving over the stop line.

Abstract: A method for detecting a traffic violation in a traffic light zone through rear end measurement by a FMCW radar device (1). A specific position (sP1) assigned to the front of a vehicle (3) and the radial velocity are derived from the measurement signal obtained at a first measurement time (t1), and a first anticipated position (eP1) for the front of the vehicle is calculated by the distance-time rule at the second measurement time (t2) by means of the time period between the first measurement time (t1) and the second measurement time (t2). Through repeated calculation of an anticipated position for the front of the vehicle at further measurement times, an anticipated time when the front of the vehicle crosses a stop line (5) defining the traffic light zone is predicted iteratively with the determined vehicle velocity.

Abstract: A method for classifying vehicles in which an angle-resolving radar device yields measurement signals which have frequencies corresponding to a Doppler shift and which originate from measured vehicles and from which radial distances, object angles and radial velocities can be derived. The frequencies of the acquired measurement signals are stored as functions over the measurement time period, and a spectrogram is formed for every vehicle therefrom. Subsequently, the spectrograms are checked for assessment regions with maximum bandwidth of the frequency. These assessment regions are compared with assessment regions of stored spectrograms for different vehicle classes and associated with the most similar such that the measured vehicles are classified.

Abstract: Method in which vehicles are measured repeatedly while traveling through a radar cone, and specific position values are formed so as to be associated with the measurement times.

The length of this section depends upon the length of the vehicle and makes classification possible.

Abstract: A method and an apparatus for identifying motor vehicles for monitoring traffic. The identification is carried out by image-evaluation and includes determining the size ratios of a license-plate contour in a perspectively distorted image on the basis of stored standardized license-plate formats, determining the size of the perspective distortion of the license-plate contour on the basis of the associated standardized license-plate format, establishing a calculation rule for the perspective rectification on the basis of the ascertained distortion of the license-plate contour with respect to the associated license-plate format, rectifying the extracted license-plate-containing motor-vehicle view, and comparing the rectified image with reference images of front views of motor vehicles stored in a database in order to assign the image with greatest correspondence to a group of classified motor vehicles.

Abstract: The invention relates to a method for carrying out a dynamic range compression in traffic photography for representation having greater detail fidelity in images created in connection with traffic monitoring installations. The problem addressed by the invention is that of finding a possibility for achieving, in the case of digitally obtained images in traffic photography, whilst precluding the different subjective influences on the part of the processing personnel, a representation of the dark regions with greater detail fidelity, without the information of the brighter regions being lost in the process. According to the invention, this problem is solved by means of a method for carrying out a specific dynamic range compression in traffic photography.

Abstract: The invention is directed to a method for detecting and documenting the speeds of a plurality of vehicles in an image document. The plurality of vehicles drive simultaneously through the measurement zone of a radiation-based, multitarget-capable measuring arrangement. Vehicle-specific measurement data are acquired from the measurement results, and measurement data sets are formed from these vehicle-specific measurement data and stored. One of the vehicles driving at a speed above a limiting value causes a camera to be triggered. An image document in which a speed is displayed so as to be assigned to the imaged vehicles is generated from the image data acquired by the camera and from the last stored measurement data set.

Abstract: The invention is directed to a method for classifying a moving vehicle. The object of the invention is to find a novel possibility for classifying vehicles moving in traffic which allows a reliable automatic classification based on two-dimensional image data. This object is met according to the invention in that an image of a vehicle is recorded by means of a camera and the position and perspective orientation of the vehicle are determined therefrom, rendered two-dimensional views are generated from three-dimensional vehicle models which are stored in a database in positions along an anticipated movement path of the vehicle and are compared with the recorded image of the vehicle, and the vehicle is classified from the two-dimensional view found to have the best match by assignment of the associated three-dimensional vehicle model.

Abstract: By means of the method according to the invention, a vehicle is detected when it drives into and out of a specified section of a roadway, the detection time is acquired, and an image recording in which the vehicle registration plate of the vehicle is detected is produced so as to be associated with each detection time. The image recordings in which the same vehicle registration plate was determined are correlated, and an average speed is determined from the difference of the associated detection times and the known length of the section of road and is compared with a specified maximum speed. If a speeding violation is determined, a high-resolution image recording of the driver of the vehicle is generated.
