Abstract

A device for recognizing a vehicle license plate number comprises a division unit for dividing a vehicle license plate image into a plurality of images such that a predetermined area is included in each of the plurality of images; and a distribution management unit for distributing the plurality of divided images to a plurality of recognizing terminals corresponding to each area and receiving the results of recognizing the corresponding area from each of the plurality of recognizing terminals.

Claims

1. A device for recognizing a vehicle license plate number comprising:

a division unit for dividing a vehicle license plate image into a plurality of images such that a predetermined area is included in each of the plurality of images; and

a distribution management unit for distributing the plurality of divided images to a plurality of recognizing terminals corresponding to each area and receiving the results of recognizing the corresponding area from each of the plurality of recognizing terminals.

2. The device for recognizing a vehicle license plate number according to claim 1, wherein the division unit divides the vehicle license plate image such that at least one area of a vehicle type, usage, a serial number, and a competent authority is included.

3. The device for recognizing a vehicle license plate number according to claim 1, further comprising:

a mergence unit for generating a predetermined vehicle license plate number on the basis of the recognizing results.

4. The device for recognizing a vehicle license plate number according to claim 3, wherein the division unit assigns an identifier for identifying the divided image to the divided image.

5. The device for recognizing a vehicle license plate number according to claim 4, wherein the mergence unit generates the predetermined vehicle license plate number by merging the recognizing results on the basis of the identifier.

6. The device for recognizing a vehicle license plate number according to claim 1, wherein the distribution management unit randomly distributes the plurality of divided images to the plurality of recognizing terminals.

7. The device for recognizing a vehicle license plate number according to claim 1, wherein the distribution management unit records and manages at least one of information of the recognizing terminals, time information on the divided image which is transmitted, location information of the recognizing terminals, and the number of recognizing which is processed by the recognizing terminals.

8. The device for recognizing a vehicle license plate number according to claim 1, wherein the recognizing terminal transmits the results of recognizing the divided images using an image processing algorithm previously stored, or transmits the recognizing results received from a user to the device for recognizing a vehicle license plate number.

9. A method for recognizing a vehicle license plate number using a device for recognizing a vehicle license plate number, the method comprising:

a step of dividing a vehicle license plate image into a plurality of images such that a predetermined area is included in each of the plurality of images;

a step of distributing the plurality of divided images to a plurality of recognizing terminals corresponding to each area; and

a step of receiving the results of recognizing the corresponding area from each of the plurality of recognizing terminals.

10. The method for recognizing a vehicle license plate number according to claim 9, wherein, in the step of dividing, the vehicle license plate image is divided such that at least one area of a vehicle type, usage, a serial number, and a competent authority is included.

11. The method for recognizing a vehicle license plate number according to claim 9, further comprising:

a step of generating a predetermined vehicle license plate number on the basis of the recognizing results.

12. The method for recognizing a vehicle license plate number according to claim 11, wherein, in the step of dividing, an identifier for identifying each of the plurality of divided images is assigned.

13. The method for recognizing a vehicle license plate number according to claim 12, wherein, in the step of generating, the vehicle license plate number is generated by merging the recognizing results received from the plurality of recognizing terminals on the basis of the identifier.

14. The method for recognizing a vehicle license plate number according to claim 9, wherein, in the step of distributing, the plurality of divided images are randomly distributed to the plurality of recognizing terminals.

15. The method for recognizing a vehicle license plate number according to claim 9, wherein, in the step of receiving the recognizing results, at least one of information of the recognizing terminals, time information on the divided image which is transmitted, location information of the recognizing terminals, and the number of recognizing which is processed by the recognizing terminals is recorded.

16. The method for recognizing a vehicle license plate number according to claim 9, wherein the recognizing terminal transmits the results of recognizing the divided images using an image processing algorithm previously stored, or transmits the recognizing results received from a user to the device for recognizing a vehicle license plate number.
