Abstract: Systems and methods for navigating a user to a destination are provided. An exemplary indoor navigation method uses a terminal device. The method includes capturing, by the terminal device, image data of an indoor scene, and determining a current position of the user based on the captured image data. The method also includes determining a navigation path and a navigation sign for navigating the user from the current position to the destination, and rendering, by the terminal device, a three-dimensional representation of the indoor scene with the navigation sign placed therein based on the image data and the navigation path. The navigation sign signals the navigation path in the three-dimensional representation. The method further includes displaying, on the terminal device, the three-dimensional representation to the user.

Abstract: The present disclosure relates to a navigation method, a device for navigation and a navigation system in the field of communication technique. Said method comprises steps of performing a location processing to obtain a location of the first terminal, acquiring a location of a second terminal; and navigating the second terminal based on navigation information from the location of the second terminal to a target location. The target location is a predetermined location or a current location of the first terminal. A first terminal for navigation comprises a location module, an acquiring module and a navigation module. A server for navigation comprises an acquiring module and a transmitting module. Said system comprises the first terminal and the server. The present disclosure accomplished a location-based navigation service and incorporated the location service and the navigation function so as to enhance the location service function and sufficiently meet with the user's requirements.
