Description
- 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. In the known methods the infraction is recorded, whereafter a camera, optionally together with a flash device, is activated and the offender is thus photographed. In order for it to function as valid testimony in the case against the offender, 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. In the known methods use was always made for this purpose of a photo or film camera with which very sharp records can be made from which the required information can easily be obtained.
- A drawback to the known methods however 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. This is achieved according to the invention in that the making of the picture record and the storing thereof take place electronically. 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. Thus, despite the often relatively limited resolution of electronic image recording means, the data required for legal use of the records can nevertheless be recorded. 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.
- In order to enable a simple processing and transmission of the records, the electronic image data is preferably digitized and stored digitally.
- A very great certainty as to the mutual correspondence of the records of the offence and the detail record of the vehicle is obtained when each picture record is built up of a number of parallel picture lines and only a limited number of mutually spaced picture lines of each picture record is included in the data file and stored, wherein the total number of picture lines included in the data file corresponds with the number of picture lines of a single picture record. Multiple images are thus as it were mutually interwoven, whereby in terms of legal evidence it is sufficiently clear that these picture records are made at the same moment.
- 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. 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.
- In preference the electronic image recording means are adapted to make at least two records at substantially the same time from different angles of view. For this purpose 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.
- The invention is now elucidated on the basis of two embodiments, wherein reference is made to the annexed drawing, in which corresponding components are designated with corresponding reference numerals, and in which:
- fig. 1 is a schematic representation of a first embodiment of a device according to the invention,
- fig. 2 is a representation corresponding with fig. 1 of a second embodiment of the device according to the invention, and
- fig. 3 shows a top view of a traffic highway along which the second embodiment of the device according to the invention is disposed.
- 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 acamera housing 14 and azoom lens 15 arranged thereon.Cameras power supply 18 and are each provided with acontrol 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. Thecontrol units 13 are connected to anexposure meter 16. Thecontrol units 13 are further connected via a so-called SCI-bus to aprocessor card 12 from which they receive instructions. - The
cameras recording control device 10 which receives control signals fromprocessor card 12 on which inter alia are arranged encrypting means. Thiscard 12 also supplies instructions to therecording control device 10 to cause the image data fromcameras recording control device 10 is also connected to aflash installation 17. The centralrecording control device 10 is further connected via anoutput line 30 and aninput line 31 to acard 11 which carries the digitizing means and which, like thecard 12 carrying the encrypting means, forms part of acomputer 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 andmodem 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. Finally, it is of course possible to connect akeyboard 19, optionally withmouse 20 and monitor 24 tocomputer 21 of device 1 and thus start up the latter by entering the appropriate commands. - When the device 1 is booted the
cameras cameras control device 10 directly ontomonitor screen 24, so that the adjustment ofcameras digitizing card 11 and transmitted vialine 31 to the centralrecording control device 10. - When all settings have been made, 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. When thedevice 22 gives a signal that an infraction is detected, this signal is transmitted viacard 12 to controldevice 10 which synchronously operates the shutters ofcameras flash 17. The images of thecameras device 10, from which they are transmitted vialine 30 to the digitizingcard 11 on which is located a number of AD converters. The transmission of the images to digitizingcard 11 is adapted under the control ofdevice 10 andprocessor card 12 such that part of the picture lines, for instance the odd picture lines, of the image fromcamera 2 are combined with part of the picture lines, for instance the even picture lines, of theother camera 3 and a digital composite picture is thus formed which includes half the image of eachcamera processor card 12 and stored on for instance a removable hard disk 4 or a tape drive 5, which can be connected tocomputer 21 via a so-called 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 theequipment 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 thecomputer 21. For this purpose the stored composite picture is again disassembled into anoverall picture 25 recorded bycamera 3 and adetail picture 26 recorded bycamera 2. Although each of thesepictures offending vehicle 27 from thedetail 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 viamodem 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. - 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. As 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 andwhite zoom cameras 2. The digitizingcard 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. In this embodiment half the picture lines (e.g. the even picture lines) of theRGB camera 3 are "interwoven" with half the picture lines (the odd picture lines) of each of the three black andwhite cameras 2. The latter are connected for this purpose to respectively the R, G or B input of theRGB digitizing card 11. In this manner and with relatively little equipment 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. - With such a device three
lanes highway 32 can for instance be monitored. The fields of view of two of the three black andwhite cameras 2 are herein shown schematically with 36 and 37 respectively. In this embodiment it is of course important that the three black andwhite cameras 2 and theRGB camera 3 are carefully synchronized.
