Abstract

According some aspects of the present invention, there is provided a method for providing an augmented reality service, including (a) receiving an image through a camera, (b) performing image matching operation on the input image in an image matching server, (c) determining by an API server whether the image can be implemented as augmented reality using a result of the image matching if the image is matched to a specific image among previously stored images, (d) providing by an AR content server augmented reality content for implementing an augmented reality scenario, if it is determined that the image can be implemented as augmented reality and (e) implementing the augmented reality using the augmented reality content by a terminal. Various images input through a camera may be implemented as augmented reality by receiving only the data needed to implement a corresponding image into the augmented reality from a server by applying an image matching technique before implementing the augmented reality, without storing the data required for implementing the augmented reality in a limited memory space of a terminal.

Claims

1. A method for providing an augmented reality service using an application programming interface (API) server, comprising:

determining, by the API server, whether content related to an input image is decided to be displayed as augmented reality based on a matching result, the matching result being received by the API server, if an image input through a camera of a terminal is determined to be matched to a specific image among previously stored images as a result of performing image matching operation on the input image as a target; and

requesting directly, by the API server, an augmented reality (AR) content server to provide augmented reality content for implementing an augmented reality scenario, or requesting, by the API server, the AR content server to provide the augmented reality content for implementing the augmented reality scenario by way of the terminal, if the content related to the input image is decided to be displayed as augmented reality.

13. The method of claim 1, wherein the API server determines whether the content on the input image correspond to a region to be displayed as augmented reality or a region to be played back as a general image and outputs content relevant to a corresponding region.

32. The method of claim 1, wherein the image matching operation is performed in the terminal or a separate image matching server.

34. A computer-readable recording medium for recording a computer program for executing a method of any one of claim 1.

35. A computer-readable recording medium for recording a computer program for executing a method of any one of claim 1.

2-5. -5. (canceled)

6. A method for providing an augmented reality service using a fourth augmented reality service providing server, comprising:

determining, by the fourth augmented reality service providing server, whether content related to an input image is decided to be displayed as augmented reality based on a matching result, if the fourth augmented reality service providing server performs image matching operation on an image as a target input through a camera of a terminal and determines that the input image is matched to a specific image among images previously stored in the fourth augmented reality service providing server; and

transmitting, by the fourth augmented reality service providing server, augmented reality content for implementing an augmented reality scenario to the terminal, the augmented reality content being extracted by the fourth augmented reality service providing server, if the content related to the input image is decided to be displayed as augmented reality.

7. The method of claim 6, wherein the image is a single image photographed through the camera or an image input in a preview state.

8. The method of claim 7, wherein if the image is input in the preview state, and if a relative position of an object moves on the image as the terminal moves, a 3D image implemented on the image also moves.

9. The method of claim 6, wherein if it is determined that feature information of the input image has high similarity with feature information of a specific image among the previously stored images as a result of the image matching operation, an identification symbol assigned to the specific image is provided as a result of the image matching.

10. The method of claim 9, wherein the identification symbol is an index number.

11. The method of claim 6, wherein determining whether the content related to the input image is decided to be displayed as augmented reality includes, determining whether the content related to the input image is determined to be displayed as the augmented reality by previously storing an identification symbol of an image that can be displayed as augmented reality and comparing an identification symbol provided as a result of the image matching operation with the previously stored identification symbol.

12. The method of claim 6, wherein the augmented reality content include an AR scenario data, a feature value data created through a trackable image data or a corresponding data, and a 3D object data, the feature value data created through the trackable image data or the corresponding data being an image data or feature information of the image data for tracking, by the terminal, a target determined to be matched by the image matching operation.

16-21. -21. (canceled)

22. A fourth augmented reality service providing server for providing an augmented reality service, comprising:

an AR region determination unit for determining whether content related to an input image is decide to be displayed as augmented reality based on a matching result, if image matching operation is performed on an image as a target input through a camera of a terminal and it is determined that the input image is matched to a specific image among previously stored images; and

a content providing unit for transmitting augmented reality content for implementing an augmented reality scenario to the terminal, the augmented reality content being extracted by the content providing unit, if the content related to the input image is decided to be displayed as augmented reality.

23. The server of claim 22, wherein the image is a single image photographed through the camera or an image input in a preview state.

24. The server of claim 23, wherein if the image is input in the preview state, and if a relative position of an object moves on the image as the terminal moves, a 3D image implemented on the image also moves.

25. The server of claim 22, wherein if it is determined that feature information of the input image has high similarity with feature information of a specific image among the previously stored images as a result of the image matching operation, an identification symbol assigned to the specific image is provided as a result of the image matching.

26. The server of claim 25, wherein the identification symbol is an index number.

27. The server of claim 22, wherein the augmented reality content include an AR scenario data, a feature value data created through a trackable image data or a corresponding data, and a 3D object data, the feature value data created through the trackable image data or the corresponding data being an image data or feature information of the image data for tracking, by the terminal, a target determined to be matched by the image matching operation.

31. The server of claim 22, wherein the fourth augmented reality service providing server determines whether the content on the input image correspond to a region to be displayed as augmented reality or a region to be played back as a general image and outputs content relevant to a corresponding region.
