Definitions

  • the invention relates to a device as generically from the US 6,696,978 B2 is known.
  • Devices for detecting traffic violations relate in particular to those which detect speed violations or red light violations. They may be permanently installed as stationary devices or temporarily stationary as mobile devices, e.g. B. in a parked vehicle or in moving vehicles.
  • invasive measuring sensors such as pressure sensors or induction loops, are preferably introduced into or onto the road surface.
  • non-invasive measurement sensors such as laser rangefinders or radar sensors are used.
  • the camera is directed onto the roadway in such a way that its object field is adapted to the measuring range determined by the measuring sensors.
  • the object field only has to detect the lanes that lie within the measuring range.
  • the object field may overlap in the direction of travel with the measuring range or lie behind him, as it is unimportant for the documentation of the infringement, where the vehicle is recorded. Rather, it is of interest that a recording is generated in which the vehicle, the license plate and / or in particular the driver are clearly visible. This is achieved by triggering the recording if that Vehicle is located at a predetermined photo point, ie at a defined distance from the camera.
  • the vehicle In the case of red light violations, on the other hand, the vehicle must be picked up at certain locations in relation to the roadway, eg. B. at the retaining strip or in the crossing area.
  • the measuring range and the object field of the camera must at least overlap.
  • the camera is oriented so that its object field, depending on the position of the measuring range, detects the road surface, ie is adapted to the measuring range.
  • the recordings contain all relevant data such as location, date, time and, if applicable, speed.
  • An evaluation of the usually recorded in the recording with license plate can be done by an official visually or by an automatic image analysis.
  • a generic device for detecting speeding offenses is from the summary of JP 05-062096 known.
  • the measured vehicle speed is compared in a comparator with a predetermined maximum speed. If the maximum speed is exceeded by the measured speed, a signal is triggered via a switch and forwarded to a camera. It is a recording created by the infringer vehicle and output as a picture signal. From the image signal, the information of the vehicle registration number is read out via an image processing unit. Together with the measured speed, the vehicle registration information is displayed in the recording and recorded in a recording unit.
  • An automatic vehicle license plate recognition device is known with which a vehicle speed can also be detected.
  • the device is equipped with a camera and a sensor which is arranged within the object field of the single-frame camera. As soon as the sensor detects a vehicle passing through the object field, the camera is triggered and a first front photo, which also shows the vehicle registration number, is generated. From the change in location distinctive features of the vehicle registration in this first front photo to a later created photo can be concluded on the speed.
  • the speed here is not derived from measured values, but derived from the image evaluation.
  • each vehicle traveling through the object field of the camera is detected here.
  • a combined laser / radar video device for detecting speed violations, in which a camera captures image data of the vehicle registration number and other identification data of a vehicle.
  • the device comprises means for measuring the speed of a target vehicle and for outputting a signal indicative of the measured speed, e.g. As a radar or a laser detector, a camera that is functionally connected to the means for speed measurement, for capturing image data of the vehicle registration of the target vehicle when the target vehicle exceeds a predetermined speed, and means for unique assignment of image data and signal.
  • the apparatus further advantageously comprises a recognition unit for recognizing the vehicle registration number of the target vehicle and a zoom drive, connected to the camera and controlled by the recognition unit, to obtain an improved registration of the vehicle license plate when a vehicle is detected at excessive speed.
  • the aforementioned devices are, except the JP 2001-126184 , designed to detect a speeding failure and to record the license plate of the infringing vehicle and to detect it automatically. This means that only the license plates of infringing vehicles are recorded.
  • JP 2001-126184 a device is proposed, with which the vehicle registration number of all the object field of a camera passing vehicles are detected in order to determine the vehicle speed via the image evaluation for license plate identification. It is unclear whether this device is capable of detecting and sanctioning a speeding violation.
  • the object of the invention is to provide a device with which traffic violations can be recorded and documented in a measuring range and, on the other hand, the vehicle registration numbers of all the vehicles passing the measuring range can be detected and recognized.
  • the device has a first camera, which is a high-resolution single-frame camera, connected to a high-power emitting in the visible spectral range flash device for receiving a vehicle, especially with well-lit face of the driver, and at least one further, low-resolution camera is present, the is connected to an illuminating device emitting in the non-visible spectral range in order to detect unnoticed for a driver whose vehicle license plate.
  • a first camera which is a high-resolution single-frame camera, connected to a high-power emitting in the visible spectral range flash device for receiving a vehicle, especially with well-lit face of the driver, and at least one further, low-resolution camera is present, the is connected to an illuminating device emitting in the non-visible spectral range in order to detect unnoticed for a driver whose vehicle license plate.
  • the first camera will only be triggered if there is a traffic violation.
  • the at least one further camera can also be a single-frame camera and is then triggered when a vehicle is in its object field, which z. B. with an invasive sensor (hardware trigger) on which the edge of the object field is aligned, is detected.
  • an invasive sensor hardware trigger
  • the means for acquiring measured values are invasive sensors, these can also be advantageously used as hardware triggers for the further cameras.
  • the at least one further camera can also be a video camera, which permanently creates sequences of images, whereby only images are evaluated if these have changes compared to previous images, which indicate that a vehicle has retracted into the object field of the camera (software trigger).
  • the recordings of the at least one further camera are evaluated with an automatic license plate reader by the license plate being detected in the recording via an image recognition software and compared with the image data of sought-after license plates stored in a computer.
  • the at least one other camera is a low-resolution camera, just enough for the image recognition of the license plate.
  • the use of more than one further camera makes it possible to adapt their object fields only to partial areas of the measuring area, such as individual lanes. With a smaller object field to be detected cameras with an even lower resolution can be used, which in turn allow an even faster reading of the recording medium.
  • the first camera detects a plurality of lanes of a lane for documenting traffic violations, it is advantageous to provide one additional lane per lane, which ensures that at most one license plate per exposure must be identified.
  • All cameras use a common computing and storage unit, whereby the determination of a traffic violation and identification of searched vehicle license plates can take place parallel to each other without mutual influencing each other.
  • the first high-resolution camera is triggered after the identification of a sought-after license plate in order to obtain an image document, which also maps the driver clearly recognizable.
  • a device comprises means for detecting measured values 1 from a vehicle traveling through a measuring range, which are suitable for proving a traffic violation.
  • Such agents are known in the art.
  • From the radar signals can also less than the speed, a distance and the angle to the radar axis of the detected vehicle are derived, whereby the vehicle can be assigned to a lane to the measured speed z. B. to compare with lane-specific maximum speeds.
  • the means for acquiring measured values 1 can also be a laser device which defines a measuring range with a single beam directed at a vehicle, a scanning single beam or a fanned single beam.
  • the distance of the measuring radiation is measured over the duration of the measuring radiation or the position of the passing vehicle to the measuring device is determined via the measuring angle and closed by the change of the position or distance to the speed.
  • Such devices are particularly suitable as temporary stationary devices for locally flexible use or as hand-held devices.
  • the measuring range is determined by radiation
  • the measuring range is determined by their Arrangement determined. It is customary to use this pressure sensors or induction loops and thus permanently create stationary devices. It detects the passing of these sensors, from which time signals are derived as measured values, with which the speed of a vehicle is usually determined via the path-time law. It can also be detected only the mere presence of the vehicle at a specific time, which is a measured value to z. B. determine a red light violation.
  • Measuring methods with the aforementioned measuring sensors provide measured values with respect to a vehicle which are suitable for proving traffic violations. In order to determine whether the measured values actually prove a traffic violation, appropriate means must be available for this purpose.
  • Measurements that can prove a traffic violation are, for. B. a speed which is greater than a predetermined limit, or a time during the red light phase of a traffic light, in which the mere presence of a vehicle, for. B. is detected behind a support bar.
  • a detected speed is a traffic violation, it is compared to a threshold.
  • the time recorded is compared with the time periods of the red phase. If the time point detection z. B. is limited by a limited to the red light phase activation of the measuring means, so that the determination of the traffic violation is already given with detection of the measured value.
  • all means which serve to assign the measured values to a traffic violation ie, for Example, a comparator, which compares a detected speed with a predetermined limit speed, or a trigger that binds a time recording and camera triggering to the switching phases of a traffic light, be understood as a means for determining the measured values as evidence of a traffic violation.

According to the different national legislations, both front and rear views can be made. When shooting at the front, the driver's face should also be clearly visible through a good illumination of the vehicle interior. For this purpose, a powerful xenon flash lamp or a power-saving illumination of at least one light-emitting diode is advantageously used.
  • a second image, clearly showing the same vehicle is usually created, in which the license plate is clearly displayed.
  • a recording may be desired in which the vehicle is visible in the traffic scene, or recordings in which the vehicle at different positions z. B. is shown in the traffic light area.

  • the illumination device 7 is advantageously either a permanently active or synchronized to the frame rate infrared illumination.
  • the infrared lighting has the advantage that it is not perceived by the driver and no glare can occur.
  • a significantly lower-power illumination is used for the illumination of the object field of the video camera, as for the illumination of the object field of the single-frame camera 3, since the identifier to be detected Usually have a highly reflective background and by the frequent combination of dark numbers and numbers on a light, especially white background have a very good contrast.
  • the image data obtained with the video camera are read in the computing and storage unit 5 in real time and held in a volatile memory.
  • suitable software by comparing the image data, changes in the image data of successive images can be detected, which give an indication as to whether a vehicle has moved into the object field of the video camera.
  • the image data of an associated or following photograph is identified in a label reader 10 by means of a picture-recognizing software integrated in the arithmetic and storage unit 5.

  • the rear photography can be identified with the first single-frame camera 3 with a high image resolution advantageous on several lanes, such as a three-lane highway, vehicles and license plates.
  • the video camera is connected to the computing and storage unit 5, but has its own second control unit 8, whereby the license plate detection and the detection of traffic violations run independently of each other.
