Abstract

A method for discovering an augmented reality (AR) object is provided that is applicable to the field of AR technologies. The method for discovering an AR object includes, when it is determined, according to a pre-generated navigation route and a movement speed of a terminal, that a vicinity of a preselected AR object is reached, determining a status of the terminal; when it is determined that the terminal is in a searching state, starting a camera and acquiring a picture; and when the acquired picture includes the AR object, notifying of the AR object.

Claims

1. A method for discovering an augmented reality (AR) object, comprising:

determining a status of a terminal when it is determined, according to a pre-generated navigation route and a movement speed of the terminal, that a vicinity of a preselected AR object is reached;

starting a camera and acquiring a picture when it is determined that the terminal is in a searching state; and

notifying of the AR object when the acquired picture comprises the AR object.

2. The method according to claim 1, wherein that it is determined, according to the pre-generated navigation route and the movement speed of the terminal, that the vicinity of the preselected AR object is reached comprises:

acquiring a distance between a position of the AR object and a starting position of the terminal according to the pre-generated navigation route;

acquiring, according to a movement manner preselected by the user, an average movement speed of the movement manner;

calculating, according to the distance and the average movement speed, an expected time for the terminal to reach the vicinity of the AR object; and

after the terminal starts from the starting position of the terminal and has moved the expected time, determining that the vicinity of the AR object is reached.

3. The method according to claim 1, wherein the method further comprises:

collecting a current position parameter of the terminal by using a navigation and positioning system when the acquired picture does not comprise the AR object; and

correcting the navigation route according to the position parameter.

4. The method according to claim 3, wherein the position parameter comprises at least one of positioning parameter information of a current position of the terminal and an obvious sign of the current position of the terminal.

5. The method according to claim 1, wherein determining the status of the terminal comprises determining, according to whether a gyroscope and a preset function are used, whether the terminal is in the searching state.

6. The method according to claim 1, further comprising outputting warning information when it is determined that the terminal moves irregularly in the vicinity of the AR object and finally goes far away from the AR object.

7. A terminal, comprising:

a status determining unit configured to determine a status of the terminal when it is determined, according to a pre-generated navigation route and a movement speed of the terminal, that a vicinity of a preselected augmented reality (AR) object is reached;

a picture acquiring unit configured to start a camera and acquire a picture when the status determining unit determines that the terminal is in a searching state; and

a notifying unit configured to notify of the AR object when the picture acquired by the picture acquiring unit comprises the AR object.

8. The terminal according to claim 7, wherein the status determining unit comprises:

a distance acquiring subunit configured to acquire a distance between a position of the AR object and a starting position of the terminal according to the pre-generated navigation route;

a speed acquiring subunit configured to acquire, according to a movement manner preselected by the user, an average movement speed of the movement manner;

an expected time acquiring subunit configured to calculate, according to the distance acquired by the distance acquiring subunit and the average movement speed acquired by the speed acquiring subunit, an expected time for the terminal to reach the vicinity of the AR object; and

a determining subunit configured to, after the terminal starts from the starting position of the terminal and has moved the expected time, determine that the vicinity of the AR object is reached.

9. The terminal according to claim 7, further comprising:

a parameter collecting unit configured to collect a current position parameter of the terminal by using a navigation and positioning system when the picture acquired by the picture acquiring unit does not comprise the AR object; and

a correcting unit configured to correct the navigation route according to the position parameter collected by the parameter collecting unit.

10. The terminal according to claim 9, wherein the position parameter comprises at least one of positioning parameter information of a current position of the terminal and an obvious sign of the current position of the terminal.

11. The terminal according to claim 7, wherein the status determining unit is configured to determine, according to whether a gyroscope and a preset function are used, whether the terminal is in the searching state when it is determined, according to the pre-generated navigation route and the movement speed of the terminal, that the vicinity of the preselected AR object is reached.

12. The terminal according to claim 7, further comprising a warning unit configured to output warning information when it is determined that the terminal moves irregularly in the vicinity of the AR object and finally goes far away from the AR object.
