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: The present disclosure discloses a map data processing method, a device, a storage medium and a program product, and relates to intelligent transportation, automatic driving, electronic map and other fields in computer technology. A specific solution is: determining, according to coordinates of vertexes of a tile included in panoramic map data, coordinates of mapping points of the tile on a plane where a viewport is located; determining a bounding box of the mapping points according to the coordinates of the mapping points; according to whether there is an overlapping area between the bounding box of the mapping points and a visible range corresponding to the viewport, determining whether the tile falls within the visible range, thus determining the indexes of all the tiles falling within the visible range. In this way, the indexes of the tiles falling within the visible range corresponding to the current viewport can be determined accurately.

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.
