Abstract: Provided are a tour guiding method and apparatus, an electronic device and a storage medium. The method includes receiving a video stream collected by a user in a current location area of a target scenic spot and sent by an application device; determining, based on the collected video stream and prestored three-dimensional point cloud data of the target scenic spot, an augmented-reality-based content resource package corresponding to the current location area, where the augmented-reality-based content resource package includes at least six-degrees-of-freedom attitude data of the application device; and sending the augmented-reality-based content resource package corresponding to the current location area to the application device to enable the application device to provide the augmented-reality-based content resource package corresponding to the front location area for the user.

Abstract: Embodiments of the present disclosure provides a method and apparatus for constructing a map. The method may include: determining pose information of each panoramic image frame from a panoramic image sequence of a target area, and determining a perspective image sequence from each panoramic image frame; determining a feature track corresponding to the panoramic image sequence based on perspective image sequences corresponding to adjacent panoramic image frames; and constructing a visual map of the target area based on the feature track and the pose information of each panoramic image frame.
