Method and system for navigation using video call

1. A computer-implemented navigation method comprising:

transmitting, from a terminal, current location-based video data during a video call, the video data comprising an image of the video call and metadata acquired from a camera;

receiving, from a counterpart terminal, instruction information for navigation based on the video data, the instruction information including route instructions between two points;

generating navigation information to display a route based on the route instructions between the two points by mapping the instruction information to the video data; and

providing the navigation information based on location information of the terminal by overlaying a layer onto features of the image of the video call, the layer including the route.

2. The method of claim 1 , wherein the providing of the navigation information comprises providing augmented reality (AR)-based navigation information generated by mapping the instruction information to the video data of the terminal, based on the location information of the terminal.

3. The method of claim 1 , wherein the mapping of the instruction information to the video data is based on a location at which the instruction information is input.

4. The method of claim 1 , wherein the receiving of the instruction information comprises receiving, from the counterpart terminal, instruction information that is input through a user interface for inputting the instruction information in response to the user interface being provided to the counterpart terminal.

5. The method of claim 1 , wherein the receiving of the instruction information comprises receiving, from the counterpart terminal, instruction information associated with a specific event input to the video data.

6. The method of claim 1 , wherein the providing of the navigation information comprises providing guidance information associated with the navigation information based on the location information of the terminal.

7. The method of claim 1 , wherein the providing of the navigation information comprises consecutively updating the navigation information based on changed location information of the terminal in response to the location information of the terminal being changed.

8. The method of claim 1 , wherein the providing of the navigation information comprises playing content including a destination route of the terminal as the navigation information in response to the content being uploaded from the counterpart terminal.

9. The method of claim 1 , wherein the providing of the navigation information comprises generating information associated with a deviation of the terminal in response to detecting an occurrence of the deviation of the terminal based on the navigation information.

10. The method of claim 1 , wherein the providing of the navigation information comprises transmitting and receiving a message between the terminal and the counterpart terminal.

11. The method of claim 1 , wherein the providing of the navigation information comprises displaying a travel route through which the terminal is moving based on the location information of the terminal.

12. The method of claim 1 , wherein the transmitting of the current location-based video data comprises transmitting, to the counterpart terminal, the current location-based video data that is input to the video call screen of the terminal, according to a camera mode that operates during the video call.

13. A non-transitory computer-readable recording medium storing instructions that, when executed by a processor, cause the processor to perform a navigation method comprising:

transmitting, from a terminal, current location-based video data during a video call, the video data comprising an image of the video call and metadata acquired from a camera;

receiving instruction information, from a counterpart terminal, for navigation based on the video data, the instruction information including route instructions between two points;

generating navigation information to display a route based on the route instructions between the two points by mapping the instruction information to the video data; and

providing the navigation information based on location information of the terminal by overlaying a layer onto features of the image of the video call, the layer including the route.

14. A navigation server comprising:

a memory configured to store instructions; and

a processor, configured to execute the instructions to

determine current location information of a terminal during a video call from video data comprising an image of the video call and metadata acquired from a camera;

acquire additional information associated with instruction information for navigation that is input based on video data of the terminal from a counterpart terminal in response to the video data of the terminal being displayed on a video call screen of the counterpart terminal, the instruction information including route instructions between two points; and

provide the additional information associated with the instruction information to the terminal to be mapped to the image of the video call as a layer including the additional information as a route, based on the route instructions, between the two points.

15. The navigation server of claim 14 , wherein the processor is configured to generate augmented reality (AR)-based navigation information by mapping the additional information associated with the instruction information to the video data.

16. The navigation server of claim 14 , wherein the processor is configured to transfer map information including the current location information of the terminal to the video call screen of the counterpart terminal.

17. The navigation server of claim 14 , wherein the processor is configured to generate guidance information based on the current location information of the terminal and the instruction information.

18. The navigation server of claim 14 , wherein the processor is configured to set a deviation range for detecting a deviation of the terminal, to determine whether the terminal is deviated based on the deviation range, and to generate an alert message.

19. The navigation server of claim 14 , wherein the processor is configured to generate the layer that includes additional information associated with the instruction information and to transmit the layer to the terminal.

20. The navigation server of claim 16 , wherein the processor is configured to display, on the video call screen of the counterpart terminal, a travel route according to location information of the terminal based on navigation information that is displayed on the video call screen of the terminal.
