For those of ordinary skill in the art, without creative efforts, other accompanying drawings can be obtained based on these drawings.

[0050] Figure 1 This is the principle block diagram of the present invention. Detailed implementation manners

[0051] The following will clearly and completely describe the technical solutions of the present invention in combination with the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0052] As Figure 1 shown, a three-dimensional meteorological display system based on the digital earth includes a data source management module, a data acquisition module, a three-dimensional display module, and an interaction module;

[0053] The data source management module is used for staff to manage meteorological data sources and form a meteorological source information table; the meteorological data source is the source of various meteorological data. For example, when it is necessary to replace or add a new meteorological data source, the staff adjusts the meteorological source information table; then, corresponding meteorological data source docking is performed to achieve corresponding meteorological data acquisition; and corresponding data processing methods are configured for the meteorological data sources in the meteorological source information table. The data processing methods are used to convert the collected meteorological data into the data format and content required for subsequent three-dimensional visualization display.

[0054] In one embodiment, an intelligent analysis method can be used to assist the staff in managing meteorological data sources. The method includes:

[0055] When the user wants to adjust the meteorological data source and there are multiple optional meteorological data sources, mark the meteorological data source to be replaced or added as the candidate data source, and determine the candidate adjustment plans according to the candidate data source. For example, if there were originally three data sources A, B, and C, and now it is planned to select one from D, E, and F as the new data source, then there are three candidate adjustment plans: ABCD, ABCE, and ABCF;

[0056] Conduct simulation analysis on each candidate adjustment plan to determine the computing resources and data processing time required for each candidate adjustment plan, and make an estimate according to the preset data processing method; Select the computing resources and data processing time corresponding to one candidate adjustment plan as the benchmark, calculate the resource ratio value and efficiency value corresponding to each candidate adjustment plan, calculate the ratio of the resources and the ratio of the data processing time, and the resource ratio value and efficiency value of the candidate adjustment plan used as the benchmark are both 1;

[0057] Calculate the screening value of the corresponding candidate adjustment plan according to the screening formula. The screening formula is:

[0058] SA = b1×ZL + b2×TA;

[0059] In the formula: SA is the screening value; b1 and b2 are both proportionality coefficients, and the value range is 0 < b1 ≤ 1, 0 < b2 ≤ 1; ZL is the resource ratio value; TA is the efficiency value;

[0060] Sort the candidate adjustment plans in ascending order of the screening value to obtain an auxiliary recommendation list; The staff determines the target adjustment plan according to the auxiliary recommendation list and adjusts the meteorological data source according to the target adjustment plan.

[0061] In one embodiment, configure the data processing method for the meteorological data source, which can be configured according to the existing method, such as determining the data processing method manually.

[0062] In one embodiment, the method for configuring the data processing method for the meteorological data source includes:

[0063] Obtain the processing requirements of the three-dimensional display for the data, integrate and set the data processing standards; Identify the meteorological data corresponding to the meteorological data source, and determine the data processing method of the corresponding meteorological data source according to the meteorological data and the data processing standards, that is, the data processing method that processes the meteorological data into data that meets the data processing standards, and mark it as the candidate method;

[0064] Conduct simulation analysis on the candidate methods to obtain the corresponding required computing resources and data processing time, and form the corresponding resource ratio value and efficiency value;

[0065] Calculate the screening value of the corresponding candidate method through the screening formula, and the above screening formula can be applied;

[0066] Select the candidate method with the lowest screening value as the data processing method of the meteorological data source.

[0067] The data acquisition module is used to collect meteorological data of corresponding meteorological data sources in real time, identify the data processing methods corresponding to the corresponding meteorological data sources according to the meteorological source information table, process the corresponding meteorological data according to the corresponding data processing methods to obtain basic display data, and send the basic display data to the 3D display module.

[0068] The 3D display module is used to display meteorological information based on the digital earth, set up a meteorological model building method, obtain basic display data, and set up a meteorological model according to the meteorological model building method and the basic display data; integrate the meteorological model with the digital earth; that is, display the meteorological model to the user in the form of an image or animation. This step involves graphics technologies such as lighting models, texture mapping, and anti-aliasing to ensure that the rendered image is both realistic and beautiful. On the digital earth, this meteorological information can be displayed in the form of being superimposed on the earth's surface or as an independent layer. Users can observe the meteorological information from different angles and scales through operations such as zooming, panning, and rotating; specifically, use existing methods for integration to obtain a meteorological display model and display the meteorological display model to the user.

[0069] In one embodiment, the meteorological model building method is set based on existing methods. Mainly use technologies such as geographic information system (GIS) and computer graphics to construct a 3D model of meteorological information according to the spatial distribution and temporal variation characteristics of meteorological data.

[0070] Cloud layer model: By analyzing satellite cloud images or radar echo data, information such as the type, height, and thickness of cloud layers can be identified, and then a 3D model of cloud layers can be constructed.

[0071] Rainfall area model: Using radar data or rainfall data output by numerical weather prediction models, the distribution and intensity of rainfall areas can be drawn, and then a 3D model of rainfall areas can be constructed.

[0072] Temperature distribution map: By analyzing ground observation stations or satellite data, temperature distribution information at different heights can be obtained, and then a 3D distribution map of temperature can be constructed.

[0073] Wind field model: Using wind speed and wind direction data, the vector field of the wind field can be calculated, and a 3D model of the wind field can be constructed through methods such as interpolation.

[0074] To improve the efficiency and accuracy of 3D modeling, intelligent algorithms and machine learning technologies can be introduced. For example, deep learning algorithms can be used to extract features and classify meteorological data to more accurately identify meteorological elements such as cloud layers and rainfall areas. In addition, machine learning algorithms can be used to train and optimize the model to improve the prediction ability and robustness of the model.

[0075] As meteorological data is continuously updated, the 3D model also needs to be updated in real-time or periodically. This can be achieved in the following ways:

[0076] Data-driven update: When new meteorological data arrives, the system can automatically compare and analyze it with the existing model, and then adjust the model accordingly based on the data changes.

[0077] Real-time rendering technology: Using an efficient rendering engine and graphics processing technology, real-time rendering and dynamic update of the 3D model can be achieved. This can ensure that users can observe the changes in meteorological information in real-time.

[0078] Integrate the corresponding 3D models into a meteorological model.

During this process, the user can manually and quickly adjust the range of the area, display information, etc.
