[0052] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0053] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0054] The existing technology does not provide clear and coherent street view images, and the real-life three-dimensional results are limited in application in non-professional fields.

[0055] This application provides a solution to introduce the traditional street view product production technology into the real-life three-dimensional field, and create panoramic geographic event products according to local conditions. The real-life three-dimensional data results have the advantages of high authenticity, high precision, good visualization effects and wide application value of geographic information.

[0056] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, a panoramic geographic event scene generation device, etc. The following takes the panoramic geographic event scene generation device as an example to illustrate this embodiment and the following embodiments.

[0057] Based on this, the present application embodiment provides a method for generating a panoramic geographic event scene, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the method for generating a panoramic geographic event scene of the present application.

[0058] In this embodiment, the method for generating a panoramic geographic event scene includes steps S10 to S60:

[0059] Step S10, obtaining the scene theme;

[0060] Furthermore, based on the scene theme, determine the scene display scope, data accuracy requirements and screen key focus objects.

[0061] It should be noted that this step is used to select hot geographical events around the scene theme, such as landslides, earthquakes and other geological disasters, and collect relevant information of hot events, including the time, location, cause, and disaster status of the events. Hot time and hot spot information can be used as the display content of the panoramic geographical event scene; analyze the scene elements, clarify the scene display scope and data accuracy requirements, and screen key focus objects, such as buildings, transportation facilities, water systems, and personnel distribution.

[0062] It is understandable that before making a panoramic product, the demand positioning should be clarified, the scene elements should be analyzed, the core theme should be highlighted, the scene script should be planned, and the scene route should be designed to provide a basis for subsequent basic data screening, virtual camera settings, and key object marking;

[0063] Step S20, determining corresponding real-scene 3D results and thematic data based on the scene theme;

[0064] It should be noted that as a standardized product of new basic surveying and mapping, the real-scene 3D results are non-scale, full-element data sets that express spatial relationships and attribute information. They have extremely strong display effects and measurable accuracy, can provide data support for panoramic geographic event products, and quickly build real-scene 3D scenes, mainly including digital elevation models (DEM), digital orthophotos (DOM), oblique photography 3D models and other geographic scenes, (2D / 3D) basic geographic entities, building (structure) structures, road facilities, underground space and other component 3D models and other professional entity data. As an important part of geographic spatial data, the real-scene 3D data results have the advantages of high authenticity, high accuracy, good visualization effects and wide application value of geographic information, which can effectively solve the data source problem of street view product production;

[0065] It is understandable that the thematic geographic information data contains rich thematic attribute information and statistical information, which can be provided to users. According to the display theme of the panoramic product, the corresponding thematic data can be obtained for statistical analysis, and the analysis results can be drawn and displayed in charts and graphs, and then superimposed on the panoramic scene for display;

[0066] Step S30, screening the real scene 3D results to obtain real scene 3D data;

[0067] It should be noted that panoramic geographic event products are lightweight real-life three-dimensional products. Compared with traditional real-life three-dimensional results, their data structure and data volume are no longer constraints on the display platform's processing performance and multi-user high-concurrency access, greatly reducing the requirements for the display terminal's hardware performance or network transmission speed.

[0068] Understandably, this strategy introduces 3D panoramic technology into the application research and market promotion of real-life 3D results for the first time, exploring specific methods for promoting real-life 3D data in the consumer market. Real-life 3D results provide the data basis for reconstructing the real environment, while 3D panoramic technology puts users in it.

[0069] Furthermore, the real-scene 3D results are screened according to the scene display scope and data accuracy requirements of the scene theme to obtain digital elevation models, digital orthophotos and oblique photography models;

[0070] The two-dimensional geographic entities in the real three-dimensional results are processed by three-dimensional symbolization to obtain three-dimensional geographic entities;

[0071] Three-dimensional geographic entities, digital elevation models, digital orthophotos and oblique photography models are used as real-life three-dimensional data.

[0072] It should be noted that two-dimensional geographic entities usually refer to various geographic elements on the map, which are presented in a flat form on the map without considering the height or three-dimensional sense; three-dimensional symbolization processing is the process of presenting geographic information data in a three-dimensional form, which is usually used in map making, GIS (Geographic Information System) visualization and virtual reality applications. This processing can make geographic entities more realistic and three-dimensional in three-dimensional space and provide richer visual information; Digital Elevation Model (DEM) is a digital terrain model used to represent the elevation information of the earth's surface. It is a commonly used data type in Geographic Information Systems (GIS); Digital Orthophoto Map (DEM) is a digital terrain model used to represent the elevation information of the earth's surface. Orthophoto is a digital map or image product that has been corrected for aerial photography or satellite remote sensing images to eliminate image distortion caused by terrain and camera perspective. This correction includes making the image have consistent proportions, right angles and equal scale properties, so that all objects in the image are displayed in an orthographic (i.e. vertical) manner at their true positions; oblique photography model is a digital map or image product obtained using oblique photography technology, using an aerial platform with an oblique photography camera to photograph the surface at different angles and directions, thereby producing images with an oblique perspective. This image acquisition technology can provide more surface details and three-dimensional sense, which is more realistic and richer than traditional vertical photography technology.

[0073] It is understandable that the spatial scope that needs to be displayed is determined according to the scene theme and application requirements. This can be an entire city, a specific area, a single building or scenic spot, etc. Consider the scale and scope of the scene to determine the geographical area that needs to be covered, and determine the accuracy requirements of the data according to the scene theme and specific application requirements. This can include horizontal and vertical accuracy, resolution, geographic reference system, etc., formulate screening criteria, and determine which objects meet the requirements of focus according to the scene theme and application requirements. The screening criteria can include aspects such as the importance of the object, geographical location, appearance characteristics, historical and cultural value, etc.

[0074] Step S40, superimposing the real-scene 3D data and the thematic data to construct a real-scene 3D scene;

[0075] Step S50, setting an observation point based on the real three-dimensional scene, acquiring images around the observation point, processing the images around the observation point to obtain a panoramic geographic event scene, and preprocessing the panoramic geographic event scene;

[0076] It can be understood that panoramic geographic event products based on real-life three-dimensional results are an innovative type of geographic information product. Based on real-life three-dimensional results such as geographic scene data and geographic entity data, various thematic data are superimposed, and three-dimensional panoramic technology is used to create an immersive virtual reality environment. Assisted by mapping elements, thematic animations, voice guides and other means, geographic events or hot spots are presented to users in the form of three-dimensional panoramas.

[0077] Step S60, obtaining auxiliary element data, loading the preprocessed panoramic geographic event scene and the auxiliary element data to the target publishing platform, and displaying the panoramic geographic event scene on the target publishing platform based on the preset roaming route.

[0078] In the specific implementation, the panoramic images and graphic data are published to the designated platform, assisted by thematic animations, voice guides and other means to display panoramic geographical event scenes based on the roaming routes.

[0079] The present embodiment provides a method for generating a panoramic geographic event scene, which includes obtaining a scene theme; determining corresponding real-life three-dimensional achievements and thematic data based on the scene theme; screening the real-life three-dimensional achievements to obtain real-life three-dimensional data; superimposing the real-life three-dimensional data and thematic data to construct a real-life three-dimensional scene; setting observation points based on the real-life three-dimensional scene, obtaining images around the observation points, processing the images around the observation points to obtain a panoramic geographic event scene, obtaining auxiliary element data, superimposing various thematic data based on real-life three-dimensional achievements such as geographic scene data and geographic entity data, using three-dimensional panoramic technology to create an immersive virtual reality environment, and using auxiliary mapping elements, thematic motion effects, voice guides and other means to present geographic events or hot spots to users in the form of three-dimensional panoramic images.

[0080] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following. Figure 2 , step S40, the method for generating a panoramic geographic event scene further includes steps S401 to S404:

[0081] Step S401, obtaining a key focus object, marking the key focus object in the real three-dimensional scene, adding display prompt information, and saving the marking in the form of a chart;

[0082] It should be noted that TIPS information is prompt information, which is used to explain key objects.

[0083] In the specific implementation, annotations are drawn for key focus objects, TIPS information is added, and the information is saved in the form of charts.

[0084] Step S402, obtaining thematic data, performing information extraction and analysis on the thematic data according to the key focus objects, and obtaining chart analysis results;

[0085] In the specific implementation, obtain thematic data, extract and analyze information around key focus objects, draw charts to record analysis results, such as bar charts, pie charts, etc., and draw data statistics and analysis results;

[0086] Step S403, writing a text introduction or recording an audio recording of the theme background, event information, product name and author information in the scene theme;

[0087] In the specific implementation, write a text introduction or record an audio to introduce the theme background, event information, product name and author information;

[0088] Step S404, superimposing the annotations, chart analysis results and textual introduction or recorded audio to obtain auxiliary element data.

[0089] It should be noted that auxiliary elements can also include dynamic characteristics: using three-dimensional model symbols to achieve dynamic effect display of specific scenes, such as landslides, water flows, seismic waves, etc., mapping elements: three-dimensional compass, coarse-grained latitude and longitude grid, etc.;

[0090] Auxiliary elements can enrich the visualization effect of real-life three-dimensional scenes and highlight the theme and core elements of the scenes.

[0091] This embodiment provides a method for generating a panoramic geographic event scene. The information carrying capacity of real-life three-dimensional data is much higher than that of street view information. It supports the overlay of geographic information and analysis of information. Regardless of the data type, such as scene data, entity data, thematic data, etc., or the data level, such as terrain level, city level and component level, it can fully cover the data resources required for the production of three-dimensional panoramic products. By associating real-life three-dimensional data, information can be updated in real time and dynamically.

[0092] Based on the first and second embodiments of the present application, in the third embodiment of the present application, the same or similar contents as those in the above embodiments can be referred to the above introduction, and will not be described in detail later. Figure 3 , step S50, the method for generating a panoramic geographic event scene further includes steps S501 to S502:

[0093] Step S501, setting an observation point and a surround model based on a real three-dimensional scene, and acquiring an image around the observation point through the surround model;

[0094] It should be noted that a surround view model is a device used to capture images or videos of the surrounding environment. It is usually composed of multiple cameras and can capture the surrounding scenery in 360 degrees. The surround view model can be a single device or an array composed of multiple cameras.

[0095] In the specific implementation, an observation point is set based on a real-life three-dimensional display scene, a surround model is used, image acquisition is started, and street view images around the current observation point are obtained.

[0096] Step S502: Based on the data model, images around the observation point are stitched into a panoramic image through image registration, correction and fusion to obtain a panoramic geographic event scene.

[0097] It should be noted that the data model can be an algorithm or software for processing the captured image data and stitching them into a panoramic image. This process can include operations such as geometric correction, color correction, feature matching and fusion of the images.

[0098] In the specific implementation, after shooting is completed, image stitching is completed based on the data model to obtain a panoramic image, and each camera independently outputs the panoramic image result;

[0099] It is understandable that the traditional way of obtaining street view data requires setting up digital cameras on site for multi-angle panoramic shooting, and cost expenditure becomes a key constraint factor. Based on the real three-dimensional scene, a virtual camera is set up for shooting. In principle, there are infinite viewing angles to publish designated hot spots or geographical events, which effectively saves data collection costs, establishes a mathematical model to automatically complete image stitching, and solves the problem of panoramic data collection in inaccessible areas.

[0100] Further, the original geographic coordinates of the panoramic geographic event scene are cleared, and relative coordinates are obtained, and the relative coordinates are used as the geographic coordinates of the panoramic geographic event scene;

[0101] Synchronously divide the panoramic geographic event scene into preset small blocks;

[0102] After encrypting each small block, the encrypted small blocks are spliced ​​together to obtain an encrypted panoramic geographic event scene.

[0103] In the specific implementation, for panoramic products, set the virtual reality space and relative coordinate benchmark, clear the original geographic coordinates of the panoramic products, input the relative coordinates, and simultaneously use methods such as image segmentation and encryption to protect the image data.

[0104] It is understandable that panoramic geographic event products continue to carry thematic information after clearing the geographic coordinates. They are released based on virtual reality space and real-life three-dimensional street view effects. They no longer rely on absolute geographic space and can further ensure data security through methods such as domain name fixed-point encryption and image segmentation encryption.

[0105] Furthermore, the panoramic geographic event scene and auxiliary element data are loaded into the target publishing platform, and corresponding hot spots are added in the background of the target publishing platform to realize the display of the auxiliary element data;

[0106] Playing the panoramic geographic event scene on the publishing platform based on the preset roaming route to display the panoramic geographic event scene;

[0107] Generate a playback link address or QR code of the panoramic geographic event scene based on the publishing platform to share the panoramic geographic event scene.

[0108] It should be noted that for the panoramic display platform, methods such as domain name fixed-point encryption can be used to specify the domain name to play the panoramic image;

[0109] It is understandable that product releases can also be achieved by connecting to virtual display devices, including VR glasses, handles, flight simulators and other real-life devices to interact with panoramic products, and by generating playback link addresses or QR codes to share panoramic products.

[0110] In the specific implementation, the panorama is loaded to the designated publishing platform, and each panorama is used as an independent unit. Roaming hotspots, audio and video hotspots, video hotspots, text hotspots, etc. are added in the background. While playing the panorama, effects such as hotspot switching and detailed display of key content are achieved.

[0111] This embodiment provides a method for generating a panoramic geographic event scene. The panoramic geographic event product directly changes the interaction mode between the user and the real three-dimensional scene, from the traditional plane display to the multimedia interactive display, and supports the connection of display devices such as VR glasses, handles, flight simulators, etc. to create an immersive virtual reality experience.

[0112] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the method for generating the panoramic geographic event scene of the present application. More simple transformations based on this technical concept are all within the scope of protection of the present application.

[0113] Figure 4 A flowchart of a method for generating a panoramic geographic event scene in this application;

[0114] Select the display theme, refine the scene elements, filter the real-life 3D data and overlay the thematic data to mark the key objects. The real-life 3D results include DOM / TDOM, basic geographic entities, DEM / DSM, component 3D models, oblique photography models, etc. The thematic data include natural disaster data, meteorological and hydrological data, etc. Build a real-life 3D scene, mark the key objects and establish the TPS of the key objects, analyze the data charts, calibrate the hotspot positions, set the observation points, enter the surround mode to shoot street view pictures, automatically stitch to obtain panoramic images, clarify the geographic coordinates of the panorama, update to relative coordinates based on unified rules, load all panoramas into the playback program or display platform, take each panorama as a hotspot, connect them in series according to time or space, and then access the mapping elements, text explanations, voice guides and display devices, including VR glasses, handle mice, flight simulators, 3D compass coarse-grained latitude and longitude grids, product introduction author information, voice guide flight routes, etc. Finally, build a 3D panoramic virtual roaming system and display it to users.
