摘要： Systems and methods for updating a model of a building are provided. The method includes obtaining a three-dimensional (3D) model of a building including reference environmental data associated with a plurality of reference locations of the building and obtaining current environmental data corresponding to a current location of the building. The method further includes identifying, from the 3D model, a target reference location corresponding to the current location from the plurality of reference locations of the building and comparing the current environmental data with the target reference environmental data. The method further includes sending to the user device the target reference location when the current environmental data match the target reference environmental data, and updating the 3D model with the current environmental data when the current environmental data statistically un-match the target reference environmental data.

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.

摘要： The present disclosure is related to systems and methods for indoor positioning. The method includes obtaining a first location of a subject at a first time point. The method also includes determining one or more motion parameters associated with the subject at least based on one or more sensors carried by the subject. The method further includes determining, based on the first location of the subject and the one or more motion parameters associated with the subject, a second location of the subject at a second time point after the first time point. The method still further includes adjusting, at least based on surroundings information associated with the subject at the second time point, the second location of the subject to determine a target location of the subject.
