Abstract
To provide navigation to a destination to a user even in a state in which acquisition of a current position via a positioning module is difficult. There is provided an image processing device including: an image acquisition unit configured to acquire an image onto which a real object including a visual recognition target is projected; a recognition unit configured to recognize relative arrangement of a terminal that has captured the image to the real object by executing image recognition of the recognition target; and a control unit configured to display a display object indicating a direction toward a destination of a user on a screen of the terminal on the basis of the relative arrangement of the terminal recognized by the recognition unit.
Background
Various navigation services for guiding a user to some destination have been implemented so far. Navigation is normally performed on the basis of knowledge regarding a position of a destination and a current position of the user. In order to acquire the current position of the user, many navigation services use a positioning module, such as a global positioning system (GPS) module or PlaceEngine (registered trademark), which is included in a terminal held by the user.
Patent Literature 1 proposes that a specified object corresponding to a place serving as a destination (e.g., buildings or facilities) be emphasized in an image so that a user can easily find the place serving as the destination on a screen of a terminal. Also in Patent Literature 1, a current position of the user is acquired via a GPS module.
Summary
Technical Problem
However, not all terminals include a positioning module. Further, even in the case where a terminal includes a positioning module, it is difficult to acquire a current position via the positioning module in an environment in which the terminal cannot receive a radio signal for positioning.
Therefore, it is desirable to achieve a mechanism capable of providing navigation to a destination to a user even in a state in which acquisition of a current position via a positioning module is difficult.
Solution to Problem
According to the present disclosure, there is provided an image processing device including: an image acquisition unit configured to acquire an image onto which a real object including a visual recognition target is projected; a recognition unit configured to recognize relative arrangement of a terminal that has captured the image to the real object by executing image recognition of the recognition target; and a control unit configured to display a display object indicating a direction toward a destination of a user on a screen of the terminal on the basis of the relative arrangement of the terminal recognized by the recognition unit.
According to the present disclosure, there is provided an image processing method executed by an image processing device, the image processing method including: acquiring an image onto which a real object including a visual recognition target is projected; recognizing relative arrangement of a terminal that has captured the image to the real object by executing image recognition of the recognition target; and displaying a display object indicating a direction toward a destination of a user on a screen of the terminal on the basis of the recognized relative arrangement of the terminal.
According to the present disclosure, there is provided a program causing a computer that controls an image processing device to function as: an image acquisition unit configured to acquire an image onto which a real object including a visual recognition target is projected; a recognition unit configured to recognize relative arrangement of a terminal that has captured the image to the real object by executing image recognition of the recognition target; and a control unit configured to display a display object indicating a direction toward a destination of a user on a screen of the terminal on the basis of the relative arrangement of the terminal recognized by the recognition unit.
Advantageous Effects of Invention
According to a technique of the present disclosure, it is possible to provide navigation to a destination to a user even in a state in which acquisition of a current position via a positioning module is difficult.
