Abstract

The present invention relates to a license plate number input device and a method therefor. The license plate number input device according to the present invention comprises: a characteristic information extraction unit for extracting characteristic information on a license plate from a vehicle image; a keypad provision unit for providing at least one input keypad on the basis of the extracted characteristic information; and an out unit for displaying input information input by a user through the provided input keypad.

The license plate number input device according to the present invention is expected to have the effect of allowing a user to input license plate number quickly and easily by providing an image of a license plate region and an input keypad on the basis of characteristic information extracted from a vehicle image.

In particular, the license plate number input device allows the license plate in the vehicle image to be more easily compared with a virtual license plate and thus is expected to have the effect of allowing easy verification while improving naked-eye discrimination of the license plate in the vehicle image.

Claims

1. A license plate number input device comprising:

a characteristic information extraction unit which extracts characteristic information of a license plate from a vehicle image;

a keypad provision unit which provides at least one input keypad on the basis of the extracted characteristic information; and

an output unit which displays input information received from a user through the provided input keypad.

2. The device of claim 1, further comprising a control unit which creates a virtual license plate based on the input information received from the user through the input keypad and provides the created virtual license plate.

3. The device of claim 2, wherein the control unit, together with the input keypad, displays a background image of the license plate based on the characteristic information through the output unit, and creates the virtual license plate by displaying the input information on the background image of the license plate.

4. The device of claim 1, wherein the keypad provision unit provides the input keypad for at least one among a color, districts, purposes of the vehicle, and numbers to the user based on the characteristic information, and receives the input information from the input keypad.

5. The device of any one of claims 1-4, further comprising an input unit which receives the input information received from user.

6. The device of any one of claims 1-4, further comprising a sound provision unit which provides text to speech (TTS) based on the input information.

7. The device of any one of claims 1-4, wherein the characteristic information includes at least one among a color, a shape and a format of the license plate, whether a specific character is included in the license plate, and information on the characters included in the license plate.

8. A license plate number input method comprising:

extracting characteristic information of a license plate from a vehicle image;

providing at least one input keypad on the basis of the extracted characteristic information; and

displaying input information received from a user through the provided input keypad.

9. The method of claim 8, further comprising creating and providing a virtual license plate based on the input information received from the user through the input keypad.

10. The method of claim 9, further comprising displaying a background image of the license plate based on the characteristic information, together with the input keypad,

wherein the creating and providing of the virtual license plate includes displaying the characteristic information on the background image of the license plate.

11. The method of claim 8, wherein the providing of the input keypad includes providing the input keypad for at least one among a color, districts, purposes of the vehicle, and numbers to the user based on the characteristic information in order to receive the input information.

12. The method of any one of claims 8-11, further comprising providing text to speech (TTS) based on the input information to the user.

13. The method of any one of claims 8-11, wherein the characteristic information includes at least one among a color, a shape and a format of the license plate, whether a specific character is included in the license plate, and information on the characters included in the license plate.
