Definitions

  • the invention relates to a method for recording an incident, in particular a traffic offence, by making at least one picture record of this incident and storing the record.
  • Such methods are generally applied for automatically recording traffic infractions, such as driving through a red light or exceeding the maximum speed limit.
  • traffic infractions such as driving through a red light or exceeding the maximum speed limit.
  • the infraction is recorded, whereafter a camera, optionally together with a flash device, is activated and the offender is thus photographed.
  • a camera optionally together with a flash device
  • the offender is thus photographed.
  • at least the licence plate of the offending vehicle and the vehicle type must be unambiguously distinguishable in the picture record, while the record must further provide a clear picture of the overall traffic situation at the time of the observed offence.
  • a drawback to the known methods is that only a comparatively limited number of records can be made with a photo or film camera before the film is used up and has to be replaced, while such photographic records moreover do not lend themselves well to automatic processing, whereby this method is labour-intensive and costly.
  • the invention therefore has for its object to provide a method for recording a traffic offence wherein these drawbacks do not occur.
  • By making electronic records use can be made for storing the records of the currently available mass storage means of electromagnetic or opto-electronic type, such as a so-called hard disk or optical disk. A considerably larger number of offences can hereby be recorded than in the known methods before replacement of the storage medium is necessary.
  • the electronically captured records can also be transmitted in simple manner, for instance via telephone lines or through the air, and such records lend themselves well to further automated electronic processing.
  • At least two picture records are preferably made at substantially the same time from different angles of view.
  • One picture record can herein be made of the overall traffic situation while another picture record can show the offending vehicle in detail.
  • the electronic image data of the two picture records are preferably entered into a single collective data file, which data file is encrypted and then stored. In this way it can be legally established with sufficient certainty that the vehicle shown in detail on one of the picture records has indeed committed the traffic offence shown as a whole in another picture record.
  • the electronic image data is preferably digitized and stored digitally.
  • the invention also relates to a device for recording an incident, in particular a traffic offence, with which the above described method can be performed.
  • a device for recording an incident in particular a traffic offence, with which the above described method can be performed.
  • Such a device is provided according to the invention with means for making a picture record in electronic manner in addition to electronic storage means.
  • the electronic image recording means are adapted to make at least two records at substantially the same time from different angles of view.
  • the electronic image recording means can comprise at least two separate cameras, but it is also conceivable that the image recording means comprise a single camera with very fast zoom lens.
  • the camera can be a video camera, for instance a so-called CCD camera.
  • a device 1 for recording an incident, in particular a traffic offence, is provided with electronic image recording means 2,3, and with electronic storage means 4,5,7.
  • the recording means 2,3 can be formed by video cameras, each provided with a shutter (not shown).
  • the camera 2 for the detail image consists of a camera housing 14 and a zoom lens 15 arranged thereon.
  • Cameras 2,3 are fed by a power supply 18 and are each provided with a control unit 13 with which different parameters of the cameras can be adjusted, such as the focus and distance, the shutter time, the iris (to optimalize light/depth of field), the amplification factor of the video signal and the correction factor for day or night recordings.
  • the control units 13 are connected to an exposure meter 16.
  • the control units 13 are further connected via a so-called SCI-bus to a processor card 12 from which they receive instructions.
  • the cameras 2,3 are each connected to a central recording control device 10 which receives control signals from processor card 12 on which inter alia are arranged encrypting means.
  • This card 12 also supplies instructions to the recording control device 10 to cause the image data from cameras 2,3 to be entered into a collective data file.
  • the central recording control device 10 is also connected to a flash installation 17.
  • the central recording control device 10 is further connected via an output line 30 and an input line 31 to a card 11 which carries the digitizing means and which, like the card 12 carrying the encrypting means, forms part of a computer 21.
  • the device can be programmed in different ways.
  • the storage means can for instance comprise a hard disk 7 on which a boot program is present. Also present is a floppy disk drive 6 in which a boot disk can be placed. It is further possible to boot the system via a modem 29 with which a user located remotely of the device 1 can communicate with the device.
  • the floppy disk drive 6, hard disk 7 and modem 29 are connected to the device via a so-called multi-I/O card 9 on which a so-called IDE-bus and RS232-bus are arranged.
  • a keyboard 19 optionally with mouse 20 and monitor 24 to computer 21 of device 1 and thus start up the latter by entering the appropriate commands.
  • the cameras 2,3 are first of all properly adjusted.
  • the image of one or more of cameras 2,3 can be projected under the influence of control device 10 directly onto monitor screen 24, so that the adjustment of cameras 2,3 can be directly monitored.
  • the system can further function independently.
  • the system is activated by a device designated schematically with 22 which senses a traffic offence, such as driving through a red light or exceeding the maximum speed limit.
  • This device 22 can consist for example of a number of loops in the road surface or a radar speed measuring device.
  • this signal is transmitted via card 12 to control device 10 which synchronously operates the shutters of cameras 2,3 and optionally the flash 17.
  • the images of the cameras 2,3 are fed to control device 10, from which they are transmitted via line 30 to the digitizing card 11 on which is located a number of AD converters.
  • the transmission of the images to digitizing card 11 is adapted under the control of device 10 and processor card 12 such that part of the picture lines, for instance the odd picture lines, of the image from camera 2 are combined with part of the picture lines, for instance the even picture lines, of the other camera 3 and a digital composite picture is thus formed which includes half the image of each camera 2,3.
  • This composite picture or combined image data file is subsequently encrypted under the control of processor card 12 and stored on for instance a removable hard disk 4 or a tape drive 5, which can be connected to computer 21 via a so-called SCSI card 8.
  • SCSI card 8 Prior to encrypting and storage further information concerning the subject of the records (an offending vehicle 27) can be added to the data file. This information is provided by the equipment 22 detecting the offence and can be presented visually in the picture in any desired manner during playback thereof.
  • the stored image can also be presented visually on for instance a monitor 28 connected via a video (SVGA) card 23 to the computer 21.
  • SVGA video
  • the stored composite picture is again disassembled into an overall picture 25 recorded by camera 3 and a detail picture 26 recorded by camera 2.
  • each of these pictures 25,26 has in one direction only half the original resolution (because only half the picture lines are stored) this is still sufficient for the intended application and it is even possible to read (if necessary electronically) the licence plate of the offending vehicle 27 from the detail record 26.
  • Various operations can be performed on the digital record. When a large number of records is stored the removable hard disk 4 can be removed. It is also possible to periodically transfer the image data on hard disk 4 or tape streamer 5 to a central processing unit via modem 29.
  • the encrypting in the card 12 serves to ensure that the electronic data file which must serve as evidence of an offence cannot be manipulated. Any accepted protocol is suitable as encrypting protocol.
  • compression technique In order to limit the amount of data which has to be stored and possibly transferred, use can be made of compression techniques, at least when the legislation in the country of use deems such a manipulation of the stored data permissible.
  • compression technique can be used so-called "lossless" techniques with which the memory requirement can be reduced by about fifty percent, or, legislation permitting, non-lossless techniques with which reduction to ten percent of the original amount of data is possible.
  • the alternative embodiment of the device according to the invention shown in fig. 2 has four cameras, a fixed RGB camera 3 and three black and white zoom cameras 2.
  • the digitizing card 11 is an RGB digitizing card which, like the black and white digitizing card shown in fig. 1, has two fields for respectively the even and odd picture lines.
  • half the picture lines (e.g. the even picture lines) of the RGB camera 3 are "interwoven" with half the picture lines (the odd picture lines) of each of the three black and white cameras 2.
  • the latter are connected for this purpose to respectively the R, G or B input of the RGB digitizing card 11.
  • three black and white detail pictures and an RGB overall picture can be reliably stored in digital form. It is also possible to thus process the images from several camera combinations as shown in fig. 1 in a single digitizing card.
  • Use of a single digitizing card results not only in a relatively low purchase price of the device 1 but also in low power consumption, while the use of space in computer 21 (the number of slots required) is moreover reduced.
  • three lanes 33,34,35 (fig. 3) of a highway 32 can for instance be monitored.
  • the fields of view of two of the three black and white cameras 2 are herein shown schematically with 36 and 37 respectively. In this embodiment it is of course important that the three black and white cameras 2 and the RGB camera 3 are carefully synchronized.
