Abstract: The present disclosure relates to a method, an apparatus and a system for generating a real scene map. The method includes: performing recognition on an acquired panorama image to obtain a target frame for each point of interest in the panorama image, where the target frame is used for selecting a point of interest through a frame, and the target frame has a position attribute, determining relative position information of each target frame with respect to the panorama image according to the position attribute of each target frame, and embedding each target frame into a preset sphere model according to the relative position information of each target frame with respect to the panorama image to obtain a panorama sphere model, and rendering the panorama sphere model to obtain a real scene map.

Abstract: A method for displaying annotation information, an electronic device and a storage medium, related to the field of computers and image information processing, are provided. The method includes: acquiring depth information and annotation information of a target region in a first image at a first angle of view; establishing an association relationship between the depth information and the annotation information; and in a case that a second image at a second angle of view is acquired, determining a display region of the target region in the second image based on the depth information, and displaying, in the display region in the second image, the annotation information of the target region based on the association relationship. Thereby, the cross-image display of the annotation information of the target region with the depth information can be realized.

Abstract: Embodiments of the present disclosure provide an information recommendation method, apparatus, device and a computer readable storage medium. The method includes: acquiring positioning information of a mobile terminal of a user; determining multiple optional geo-fences based on the positioning information; and determining a pre-recommended geo-fence based on the positioning information and weight information of the acquired multiple optional geo-fences; and generating recommendation information of the pre-recommended geo-fence in case that a position corresponding to the positioning information falls within the range of the pre-recommended geo-fence. The embodiments of the present disclosure can improve the recommendation accuracy.
