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 determining a visible angle of a target object, an electronic device, and a storage medium are provided. The method includes: acquiring first point of interest POI data of the target object, second POI data of an occluder, and a position of an observation point; determining a first tangent line and a second tangent line of the target object, passing through the position of the observation point, according to the first POI data and the position of the observation point; determining a third tangent line and a fourth tangent line of the occluder, passing through the position of the observation point, according to the second POI data and the position of the observation point; and determining a target visible angle of the target object relative to the occluder according to the first tangent line, the second tangent line, the third tangent line, and the fourth tangent line.
