Abstract

Methods and systems for uniquely identifying a vehicle that has committed a potential violation are disclosed. One method comprises the steps of: obtaining first data for uniquely identifying vehicles that enter a zone of interest (610); obtaining second data relating to a potential violation committed by a particular vehicle in the zone of interest (620); correlating the first and second data to identify a portion of the first data recorded while the particular vehicle was present in the zone of interest (630); extracting a unique identifier of the particular vehicle from the first data (640); and recording the unique identifier and an association between the unique identifier and the second data (650).

7. A method according to claim 1, wherein said first data comprises a sequence of digital images.

8. A method according to claim 7, wherein said first data is recorded at said zone of interest.

9. A method according to claim 7, wherein said first data is recorded at a location remote from said zone of interest.

10. A method according to claim 8, wherein said first data is recorded by a portable digital camera.

11. A method according to claim 2, wherein said step of determining that a particular vehicle has committed a potential violation is performed using a device adapted to detect presence of a vehicle in said zone of interest.

12. A method according to claim 11, wherein said device comprises a vehicle detector comprising a magneto-resistive sensor.

13. A method according to claim 1, wherein said step of correlating said first and second data is performed after said vehicle has left said zone of interest.

14. A method according to claim 7, wherein said step of correlating said first and second data comprises identifying one or more of said digital images that were captured while said particular vehicle was potentially committing said violation.

15. A method according to claim 1, wherein said step of extracting a unique identifier of said particular vehicle from said first data comprises the step of retrieving said vehicle'"'"'s license registration number from at least one of said digital images.

16. A method according to claim 1, comprising the further step of extracting a unique identifier of said zone of interest based on said identified portion of first data.

17. A method according to claim 16, wherein said zone of interest comprises a parking bay and said step of extracting a unique identifier of said zone of interest based on said identified portion of first data comprises the step of retrieving a unique parking bay identification number from said identified portion of first data.

18. A computer system for uniquely identifying a vehicle that has committed a potential violation, said system comprising:

memory for storing data and software program instructions;

an input/output interface for receiving and transmitting data;

a video display for displaying information; and

at least one processor coupled to said memory, said input/output interface and said video display, said at least one processor programmed to;

obtain, via said input/output interface, first data for uniquely identifying vehicles that enter a zone of interest;

obtain second data relating to a potential violation committed by a particular vehicle in said zone of interest;

correlate said first and second data to identify a portion of said first data which was recorded while said particular vehicle was present in said zone of interest;

extract a unique identifier of said particular vehicle from said first data; and

record said unique identifier and an association between said unique identifier and said second data.

19. The computer system according to claim 18, wherein said first and second data are independently obtained.

20. A computer system according to claim 18, wherein said first and second data are obtained from separate distinct sources.

21. A computer system according to claim 18, wherein said first data is obtained prior to obtaining said second data.

22. A computer system according to claim 18, wherein said first data comprises a sequence of digital images.

23. A computer system according to claim 22, wherein said first data is recorded at said zone of interest.

24. A computer system according to claim 22, wherein said first data is recorded at a location remote from said zone of interest.

25. A computer system according to claim 18, wherein second data comprises magnetic data generated by a vehicle detector comprising a magneto-resistive sensor.

26. A computer system according to claim 22, wherein said at least one processor is programmed to identify one or more of said digital images that were captured while said particular vehicle was committing said potential violation.

27. A computer system according to claim 18, wherein said at least one processor is programmed to retrieve said vehicle'"'"'s license registration number from at least one of said digital images.

28. A computer system according to claim 18, wherein said at least one processor is further programmed to extract a unique identifier of said zone of interest based on said identified portion of first data.

29. A computer system according to claim 28, wherein said zone of interest comprises a parking bay and said wherein said at least one processor is programmed to retrieve a unique parking bay identification number from said identified portion of first data.
