摘要： 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.
