The method for three-dimensionally constructing a scene in real scenery according to claim 4, wherein: in step S4, at least one base map is selected and set as default loading during the base map configuration, otherwise, the newly constructed scene cannot be initialized, and the topographic map layer configuration and the service layer configuration are configured according to requirements, where the base map configuration, the topographic map layer configuration and the service layer configuration are the same as the base map configuration in the initial layer, the topographic map layer configuration in the initial layer and the service layer configuration in the initial layer, and the tool configuration method is the same as the initial tool configuration method.
6. The method for three-dimensionally constructing a scene in real scenery according to claim 5, wherein: the content of the custom data configuration comprises three-dimensional viewpoint data configuration, wherein the three-dimensional viewpoint is used for designating and controlling the observation position and direction in a three-dimensional scene, and the position, the direction and the visual field range of a camera are controlled by setting the viewpoint, so that the content seen by a user in the scene is determined, the viewpoint allows the user to freely navigate and browse on the three-dimensional earth, and different geographic features and geographic data are observed; when the viewpoint data is transferred, selecting whether to be checked as a scene initial viewpoint according to the requirement, if the scene initial viewpoint is configured, directly jumping to the initial viewpoint when the newly constructed scene is initialized, otherwise, displaying the high-altitude three-dimensional earth when the scene is initialized.
7. The method for three-dimensionally constructing a scene in real scenery according to claim 6, wherein: the content of the custom data configuration also comprises a three-dimensional roaming data configuration, wherein the three-dimensional roaming refers to a process of free movement and browsing in a three-dimensional earth scene, the three-dimensional roaming refers to a process of free navigation and exploration of geographic topography, buildings, landmarks and other geographic data by a user in a virtual three-dimensional environment, through the three-dimensional roaming, the user uses an interactive tool or an input device to control the movement of a viewpoint, the user interacts with the geographic data in an intuitive manner, and obtains deeper understanding about geographic positions and environments; and during the three-dimensional roaming data transmission, the configuration is directly carried out according to the requirement.
8. The method for three-dimensionally constructing a scene in real scenery according to claim 7, wherein: the content of the custom data configuration also comprises three-dimensional plotting data configuration, wherein the three-dimensional plotting refers to text or graphic labels associated with geographic entities in a three-dimensional earth scene and is used for displaying related information in the scene so as to enhance understanding and interaction of users on geographic data, and when the three-dimensional data is plotted, different groups are required to be set and visible distances of the groups are required to be set so as to ensure that three-dimensional plotting data in different groups are displayed on demand in different visible distances.
9. The method for three-dimensionally constructing a scene in real scenery according to claim 8, wherein: the content of the custom data configuration also comprises three-dimensional video fusion data configuration, wherein three-dimensional video fusion is to combine three-dimensional geographic space data and video content to create an interactive experience, so that a user browses and watches the video content on a map, and real-time video streams are matched with geographic position data, so that the user can watch videos related to geographic positions on the map, and the configuration and initial display are directly carried out as required when the three-dimensional video fusion data are transmitted.
10. The method for three-dimensionally constructing a scene in real scenery according to claim 9, wherein: in step S5, the required content met by the new scene includes accuracy and integrity requirements, visualization requirements, functionality requirements, performance requirements and user experience requirements, if all the new scene meets the accuracy and integrity requirements, visualization requirements, functionality requirements, performance requirements and user experience requirements, the method proceeds to S6, and if at least one of the accuracy and integrity requirements, visualization requirements, functionality requirements, performance requirements and user experience requirements in the new scene does not meet the accuracy and integrity requirements, the method proceeds to S7.
