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, the device being communicated with a plurality of terminals, the device comprising:

at least one or more units, communicated with the plurality of terminals, the one or more units being configured and executed by a processor using an algorithm associated with least one non-transitory storage device, the units comprising,

division unit, executed by the processor, 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 assigning an identifier to each divided image;

a distribution management unit, executed by the processor, for randomly distributing the plurality of divided images to the plurality of terminals and receiving the results of recognizing the divided image from each of the plurality of terminals; and

a mergence unit, executed by the processor, for generating a predetermined vehicle license plate number by merging the recognizing results on the basis of the identifier.

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, wherein the distribution management unit records and manages at least one of information of the terminals, time information on the divided image which is transmitted, location information of the terminals, and the number of recognizing which is processed by the terminals.

4. 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.

5. A computer-implemented 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 and assigning an identifier to each divided image;

a step of randomly distributing the plurality of divided images to a plurality of terminals;

a step of receiving the results of recognizing the divided image from each of the plurality of terminals; and

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

6. The method for recognizing a vehicle license plate number according to claim 5, 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.

7. The method for recognizing a vehicle license plate number according to claim 5, wherein, in the step of receiving the recognizing results, at least one of information of the terminals, time information on the divided image which is transmitted, location information of the terminals, and the number of recognizing which is processed by the terminals is recorded.

8. The method for recognizing a vehicle license plate number according to claim 5, 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.
