[0055] Embodiment 1

[0056] Embodiment 1 of the present invention provides a method for quickly locating a space target in the sky based on a three-dimensional earth. The method builds a three-dimensional earth and an application on the earth based on Cesium, and uses common programming languages ​​such as java, html, js, and sql, including:

[0057] S1, preprocessing the acquired raw data to obtain target data in a standard format, and classifying and storing the target data in the standard format in a server.

[0058] Among them, the original data includes astronomical observation data, satellite data and / or simulation data; such as: star position, satellite number, satellite orbit, weather data, entity information, etc. The original data supports importing from external systems, and can also be imported using local device files. The preprocessing method includes: for example, for position data and time data, coordinate conversion and unit conversion operations can be performed to convert them into the required standard format so that they can be directly used by the system, and the original data is cleaned to solve problems such as data duplication, missing, and abnormalities. In this embodiment, CZML format data is mainly relied on as the system data driving method. The target data includes attitude data, such as: dynamic data such as orbits and attitudes and / or basic data, such as satellites, payloads, etc.; the types of target data include: attitude data type or basic data type; the storage method corresponding to the type of target data is file storage or database storage, which is convenient for subsequent scene playback; such as: using mysql to store basic data, and using files to store attitude data. The methods of classified storage include: adding tags and / or catalog indexes for query to the target data to optimize its query performance for use in the subsequent data presentation stage; classified storage based on the type of target data; storing backup data at the same time as the classified stored target data, and restoring the classified stored target data through the backup data as needed to ensure data security and reliability.

[0059] S2, selecting a 3D modeling tool that matches the target data, and constructing a 3D earth model corresponding to the target data based on the 3D modeling tool; or modifying the stored 3D model to construct a 3D earth model corresponding to the target data.

[0060] Among them, the 3D modeling tools include Blender or 3DMax; the type of equipment bound to the stored 3D model. When the scene is running, the equipment can match different 3D models according to the equipment type. On the model binding page, the bound model can be modified independently. The modification operations include: stretching and rotating the stored 3D model, using textures and adjusting texture parameters and / or adding lighting effects and adjusting the position, type and intensity of the light; for example, using textures: textures can add richer surface effects to the model. In the Blender software, you can select a suitable texture image and map it to the surface of the model. By adjusting the parameters of the texture, such as repetition and scaling, the texture effect can be made more realistic. Another example: adding lighting effects: good lighting can add realism to the building model. In the Blender software, through the lighting calculation algorithm: through the commonly used lighting calculation algorithms, including the sun position calculation algorithm, the shadow calculation algorithm, the lighting intensity calculation algorithm, etc., the position, type and intensity of the light can be adjusted to obtain the desired lighting effect. Appropriate lighting can highlight the details of the model and make it more three-dimensional and textured, so as to better display the sky area data.

[0061] The present invention also includes the step of importing the constructed three-dimensional earth model corresponding to the target data into the system through a preset format, such as 3D Tiles, glTF, KML, GeoJSON and other data formats supported by Cesium.

[0062] S3, divide the earth surface in the three-dimensional earth model into a preset number of earth grids; divide the sky into a preset number of sky area grids and generate corresponding sky area numbers; use the spherical triangle formula to calculate the distance between the earth grid and the sky area grid to form a closed grid area; make a topological comparison based on the longitude and latitude of the target satellite position in the target data and the longitude and latitude of the sky area grid position to obtain the position of the target satellite in the sky area grid; hide the information except the sky area grid where the target satellite is located, display the required information in the sky area grid where the target satellite is located, and save the required information.

[0063] The specific steps for dividing the grid area are as follows:

[0064] 1. Gridding the Earth

[0065] First, the earth is gridded, and the earth's surface is divided into multiple grids. Each grid is determined by three parameters: longitude, latitude, and altitude, and can be represented by a triple. For example, a grid can be represented as (120°E, 30°N, 0m), which means that the longitude is 120°E, the latitude is 30°N, and the altitude is 0 meters.

[0066] 2. Grid the sky

[0067] Grid the sky area, divide the sky into multiple grids and generate sky area numbers. Each grid is determined by three parameters: right ascension, declination and distance, and can be represented by a triple. For example, a grid can be represented as (120°, 30°, 1000km), which means right ascension is 120°, declination is 30°, and distance is 1000 kilometers.

[0068] 3. Calculate the distance between grids

[0069] Calculate the distance between the Earth grid and the sky grid. Use the spherical triangle formula to calculate the distance between the two grids to form a closed space region. Specifically, the distance between the two grids can be calculated using the following formula:

[0070] s=arccos(sin(lat1)×sin(lat2)+cos(lat1)×cos(lat2)×cos(lon2-lon1))×R

[0071] Among them, lat1 and lat2 are the latitudes of the two grids, lon1 and lon2 are the longitudes of the two grids, R is the radius of the earth, and s is the distance between the two grids.

[0072] The purpose of calculating the distance between grids is to facilitate the calculation of whether the equipment passes through the sky area block. When a task is triggered, the sky area block is highlighted.

[0073] 4Quickly locate the target satellite

[0074] The target satellite is quickly located according to the sky grid. Specifically, the distance between the target satellite and each sky grid can be calculated, and the nearest sky grid can be found. Then, the position of the target satellite can be calculated based on the position of the sky grid and the direction vector of the target satellite. In this way, the target satellite can be quickly located. Specifically: the latitude and longitude of the current position of the target satellite are compared with the latitude of the longitude position of the sky grid to determine whether the target satellite is in the sky grid, so as to achieve the effect of quickly locating the target satellite.

[0075] When in use, the user sets the parameters such as the grid interval and elevation of the sky area, the sky area number, etc. After the setting is completed, the sky area grid division can be displayed in real time; the user can select the sky area grid where a certain target point is located as the focus point. When the user completes the setting, the system information generated by all space targets and entities in the sky area will be shielded, which is convenient for users to identify useful information. According to the topological relationship comparison between the longitude and latitude of the current location of the target satellite and the longitude and latitude of the sky area grid, the system information of the sky area grid where the non-selected target satellite position point is located is filtered to achieve the effect of sky area grid block selection. Users can adjust or save their own sky area grid configuration according to actual needs for next use.

[0076] S4, quickly locate the position of the sky area grid according to the sky area number received in the search box or the satellite number in the target data; or automatically mark the position of the sky area grid corresponding to the area that meets the preset conditions according to the preset conditions; based on the required information saved, display the position and trajectory of the sky area grid of the target satellite in the target data after rapid positioning or marking.

[0077] Among them, according to preset conditions, the position of the sky area grid corresponding to the area that meets the preset conditions is automatically marked, including: when a preset frequency event occurs in a specific area within a preset time, according to the preset conditions, the position of the sky area grid corresponding to the specific area is automatically marked.

[0078] For example, before the scene starts, an equipment warning event is configured. When the scene runs to the moment when the event occurs, the software will automatically collect the location information of the sky area where the equipment is located and automatically mark the sky area block, so that the commander can notice the event at the first time.

[0079] like Figure 1 As shown, when in use, after the present invention is initialized and the three-dimensional earth is loaded, it will present the sky area grid according to the user's sky area configuration. If the user does not preset the sky area configuration, the system default configuration will be loaded. After the user selects the target sky area or target point, the focus will be set to the sky area, and the event messages generated by other sky areas will be ignored. If a certain area has concentrated multiple high-level event messages, the sky area in this area will be automatically marked as a hot spot area by the system, and the sky area will be displayed, such as a flashing prompt, and the line of sight area will be located in this area. When the user cancels the sky area positioning in this area, the sky area will stop flashing, the hot spot area mark will be cancelled, and the process ends. When the user cancels the current positioning, the system will determine that the commander no longer cares about the current sky area, obtain the current flashing sky area according to the current flashing sky area ID, and cancel the flashing effect.
