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: A method and apparatus for generating location information, an electronic device, and a computer readable storage medium are provided. The method may include: constructing a corresponding plane equation based on three-dimensional space coordinates of a matching feature pair of a target plane object included in a pair of adjacent image frames having a frame interval less than a preset interval; merging identical plane equations in generated plane equations to obtain a target plane equation, and finally calculating to obtain real corner coordinates of the target plane object, based on corner theoretical coordinates of a graphic box on a plane corresponding to the target plane equation and gravity information of the target plane object.
