Description

Technical Field

[0001] This application relates to the field of computer technology, and in particular to a data processing method and apparatus. Background Technology

[0002] Currently, the process of dividing a geographic region into geographic rasters typically involves users manually dividing the area based on online maps. This method not only requires the use of online map interfaces but also results in low accuracy and a lengthy process. Therefore, obtaining more accurate geographic rasters has become a pressing issue that needs to be addressed. Summary of the Invention

[0003] This invention provides a data processing method and apparatus that can produce geographic rasters with higher accuracy.

[0004] In a first aspect, this application provides a data processing method, which includes: acquiring first latitude and longitude data of a data processing device; determining second latitude and longitude data based on a first parameter value in a first direction of the data processing device; determining third latitude and longitude data based on a second parameter value in a second direction perpendicular to the first direction of the data processing device; determining fourth latitude and longitude data based on the second latitude and longitude data and the third latitude and longitude data; and determining the geographic grid corresponding to the data processing device based on the first latitude and longitude data, the second latitude and longitude data, the third latitude and longitude data, and the fourth latitude and longitude data.

[0005] It is evident that by determining the second, third, and fourth latitude and longitude data, the data processing device can obtain a more accurate geographic raster. Based on this more accurate geographic raster, the data processing device can then obtain the corresponding geographic raster network, thereby improving the accuracy of the geographic raster network.

[0006] In one implementation, the first latitude and longitude data is converted into first projected coordinate data using a projected coordinate system; first reference projected coordinate data is determined based on the first parameter value in the first direction of the data processing device and the first projected coordinate data; the first reference projected coordinate data is converted into first reference latitude and longitude data using a geographic coordinate system; and second latitude and longitude data is determined based on the first reference latitude and longitude data.

[0007] As can be seen, the data processing device can determine the first reference projected coordinates based on the first parameter value and the first projected coordinate data in the first direction of the data processing device; and through the projected coordinate system and the geographic coordinate system, it can perform the conversion between latitude and longitude data and projected coordinate data to obtain the first reference latitude and longitude data. Then, in the subsequent iterative correction process, a more accurate second latitude and longitude data can be determined based on the first reference latitude and longitude data.

[0008] In one implementation, if the difference between the first arc length and the first parameter value meets a preset condition, the first reference latitude and longitude data is determined as the second latitude and longitude data; the first arc length is determined based on the first reference latitude and longitude data and the first latitude and longitude data.

[0009] As can be seen, by judging whether the difference between the first arc length and the first parameter value meets the preset conditions, the data processing device can control the difference between the first arc length and the first parameter value within the preset precision, thereby making the determined second latitude and longitude data more accurate, and thus improving the accuracy of the geographic grid.

[0010] In one implementation, if the difference between the first arc length and the first parameter value does not meet a preset condition, second reference projection coordinate data is determined based on the first reference latitude and longitude data, the first latitude and longitude data, and the first reference projected coordinate data; the second reference projected coordinate data is converted into second reference latitude and longitude data through a geographic coordinate system; if the difference between the second arc length and the first parameter value meets a preset condition, the second reference latitude and longitude data is determined as the second latitude and longitude data; the second arc length is determined based on the second reference latitude and longitude data and the first latitude and longitude data.

[0011] It is evident that when the data processing device determines that the difference between the first arc length and the first parameter value does not meet the preset conditions, it can obtain the corrected second reference projection coordinate data by correcting the first reference projection coordinate data. Furthermore, by determining whether the second reference latitude and longitude data corresponding to the second reference projection coordinate data is accurate, it can obtain the second latitude and longitude data with higher accuracy, thereby improving the accuracy of the geographic grid.

[0012] In one implementation, a first geographic grid is determined based on first, second, third, and fourth latitude and longitude data; a second geographic grid is determined based on the second latitude and longitude data; a third geographic grid is determined based on the third latitude and longitude data; a fourth geographic grid is determined based on the fourth latitude and longitude data; and a geographic grid corresponding to the data processing device is determined based on the first, second, third, and fourth geographic grids.

[0013] It is evident that by defining a first, second, third, and fourth geographic raster with uniform specifications, data processing equipment can obtain a geographic raster network with uniform specifications, thereby improving the accuracy of the geographic raster network.

[0014] In one implementation, fifth latitude and longitude data are determined based on a first parameter value in a first direction of a first coordinate point; the first coordinate point is the coordinate point corresponding to the second latitude and longitude data; sixth latitude and longitude data are determined based on a second parameter value in a second direction of the first coordinate point; the second direction is perpendicular to the first direction; seventh latitude and longitude data are determined based on the fifth and sixth latitude and longitude data; and a second geographic grid is determined based on the second, fifth, sixth, and seventh latitude and longitude data.

[0015] As can be seen, the data processing equipment can use the first coordinate point as the center to determine the second geographic grid corresponding to the first coordinate point, thereby obtaining a second geographic grid with the same specifications as the first geographic grid, and then obtaining a geographic grid with uniform specifications, so as to improve the accuracy of the geographic grid.

[0016] In one implementation, the fourth latitude and longitude data is determined based on the longitude data corresponding to the second latitude and longitude data and the latitude data corresponding to the third latitude and longitude data; and / or, the fourth latitude and longitude data is determined based on the latitude data corresponding to the second latitude and longitude data and the longitude data corresponding to the third latitude and longitude data.

[0017] It is evident that by using more accurate second and third latitude and longitude data, the data processing equipment can make the determined fourth latitude and longitude data more accurate, thereby making the first geographic grid determined based on the first, second, third, and fourth latitude and longitude data more accurate, and thus improving the accuracy of the geographic grid.

[0018] Secondly, this application provides a data processing apparatus, comprising: an acquisition unit for acquiring first latitude and longitude data of a data processing device; a determination unit for determining second latitude and longitude data based on a first parameter value in a first direction of the data processing device; the determination unit further for determining third latitude and longitude data based on a second parameter value in a second direction of the data processing device; the second direction being perpendicular to the first direction; the determination unit further for determining fourth latitude and longitude data based on the second and third latitude and longitude data; and the determination unit further for determining a geographic grid corresponding to the data processing device based on the first, second, third, and fourth latitude and longitude data.

[0019] Thirdly, this application provides a data processing device, including a processor, a memory, a communication interface, and a memory interconnected with each other. The memory stores a computer program, and when the computer program is executed by the processor, the processor performs the data processing method described in the first aspect and any possible implementation thereof.

[0020] Fourthly, this application provides a computer-readable storage medium storing a computer program, the computer program including program instructions, which, when executed by a processor, perform the data processing method described in the first aspect and any possible implementation thereof.

[0021] Fifthly, this application provides a computer program product comprising a computer program or computer instructions, which, when executed by a processor, performs the data processing method described in the first aspect and any possible implementation thereof. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] To facilitate understanding, we will first introduce the background concepts involved in this application.

[0035] 1. Geographic Raster (Network)

[0036] Based on a reference coordinate point, the corresponding geographical area can be uniformly divided to obtain a geographical grid consisting of individual geographical grates (e.g., 100m*100m or 200m*200m). By dividing the geographical area into geographical grates, the data collected by IoT devices, network devices, or other devices can be combined with the geographical grid during data acquisition, thereby enabling a better, more convenient, and more efficient extraction of the value of the collected data.

[0037] For example, taking IoT devices as an example, the data collected by IoT devices typically only reflects the geographical location of the device. However, if the data from these IoT devices is aggregated into corresponding geographic grids, the data can be gathered at the grid level for subsequent data processing and analysis. This allows for a point-to-area relationship between the data collected by the IoT devices and the geographic region, rather than just a simple point-to-point relationship between the IoT device and its geographical location. For instance, with temperature measuring instruments, the data processing device can average all the temperature data reported by all temperature measuring instruments within a specific geographic grid to obtain an average temperature value, thus reflecting the temperature conditions of the geographic area where that grid is located.

[0038] 2. Geographic coordinate system

[0039] A geographic coordinate system typically refers to a coordinate system composed of longitude, latitude, and altitude, which can mark any location on Earth. It should be noted that there are various commonly used geographic coordinate systems. This application uses the 1984 Coordinate System of Geodesy (WGS84), the most widely used internationally and domestically, as an example for illustration, and this does not constitute a limitation on this application.

[0040] 3. Projected coordinate systems

[0041] Since geographic coordinate systems are three-dimensional, to display a geographic location on a map or screen, it needs to be transformed into a two-dimensional location. This process is called map projection, and a projected coordinate system corresponding to the geographic coordinate system can be obtained from this. It is understandable that transforming the geographic coordinate system into a two-dimensional projected coordinate system makes it easier to measure the distance between points. Commonly used projection methods include the Gauss-Kruger projection and the Mercator projection. In this embodiment, the Gauss-Kruger projection is used for the projection transformation of latitude and longitude coordinates, which does not constitute a limitation on this application.

[0042] 4. Arc length

[0043] Arc length refers to the length of the arc between any two points on a sphere. In the embodiments of this application, the geographic coordinate system involved uses an assumed reference ellipsoid, such as the WGS84 coordinate system, which is a widely used reference ellipsoid model. The reference ellipsoid is a mathematically defined surface of the Earth. Each reference ellipsoid model has a standard mathematical formula for calculation, which can be used to calculate the spherical arc length and azimuth angle between any two points on the surface of the reference ellipsoid.

[0044] Understandably, in the application scenario of this application, the distance between two points (as mentioned in the first parameter value below) is on the order of hundreds of meters, and the arc length corresponding to hundreds of meters can be ignored. Therefore, the distance between two coordinate points (as mentioned in the reference coordinate point and the first reference coordinate point below) and the arc length of these two coordinate points on the sphere can be considered equal.

[0045] Therefore, embodiments of this application provide a data processing method that can obtain geographic rasters with higher accuracy. The data processing method provided in embodiments of this application can be implemented based on cloud technology.

[0046] Cloud technology refers to a hosting technology that unifies hardware, software, and network resources within a wide area network (WAN) or local area network (LAN) to enable data computation, storage, processing, and sharing. Based on the cloud computing business model, cloud technology encompasses network technology, information technology, integration technology, management platform technology, and application technology. It can form resource pools, allowing for flexible and convenient on-demand resource utilization.

[0047] Cloud computing is a computing model that distributes computing tasks across a large pool of computers, enabling various application systems to access computing power, storage space, and information services as needed. The network providing these resources is called the "cloud." From the user's perspective, resources in the "cloud" appear infinitely scalable, readily available, on-demand, and expandable, with payment based on usage.

[0048] Cloud storage is a new concept that extends and develops from the concept of cloud computing. A distributed cloud storage system (hereinafter referred to as a storage system) refers to a storage system that uses cluster applications, grid technology, and distributed storage file systems to bring together a large number of storage devices of various types (storage devices are also called storage nodes) in the network to work together through application software or application interfaces to provide data storage and business access functions to the outside world.

[0049] A database, simply put, can be viewed as an electronic filing cabinet—a place to store electronic files, where users can perform operations such as adding, querying, updating, and deleting data. A "database" is a collection of data stored together in a certain way, capable of being shared by multiple users, with minimal redundancy, and independent of application programs.

[0050] In feasible embodiments, the data processing method provided in this application may specifically involve one or more of cloud technologies, such as cloud computing, cloud storage, and cloud databases. For example, it may determine the second latitude and longitude data through cloud computing, or obtain the first latitude and longitude data of the data processing device from a cloud database, or store the geographic grid corresponding to the data processing device through cloud storage.

[0051] Please see Figure 1 This is an architecture diagram of a data processing system provided in an embodiment of this application. The data processing system may include a data processing device 10 and a database 11. The data processing device 10 can determine the geographic grid corresponding to the data processing device with the first latitude and longitude data as its vertices by acquiring the latitude and longitude data of its own geographical location (e.g., first latitude and longitude data). The data processing device 10 may be a server or a terminal device with data processing capabilities; the server may be an independent physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server providing basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, CDN, and big data and artificial intelligence platforms, etc. The terminal device may be a tablet computer, laptop computer, desktop computer, etc., but is not limited to these.

[0052] Database 11 can be used to store relevant data from the data processing device 10, such as the latitude and longitude data corresponding to the data processing device, and the data obtained by the data processing device 10 during the calculation process. Database 11 can be a local database of the data processing device 10, or a cloud database accessible by the data processing device 10. It should be noted that... Figure 1 The example described uses database 11 as an example, where the latitude and longitude data of the geographical location of data processing device 10 and the latitude and longitude data determined by data processing device 10 during the calculation process are both stored. This does not limit the scope of this application. Optionally, the latitude and longitude data of the geographical location of data processing device 10 can be stored in one database, and the latitude and longitude data determined by data processing device 10 during the calculation process can be stored in another database. This application does not impose any restrictions on this.

[0053] In one implementation, the data processing device 10 can obtain the latitude and longitude data of the data processing device from the database 11 in the manner described above, and store the latitude and longitude data determined in the subsequent calculation process in the database 11.

[0054] In another implementation, the data processing device 10 may also store the latitude and longitude data of the data processing device in its own memory, retrieve the latitude and longitude data from its own memory, and store the latitude and longitude data determined in subsequent calculations in its own memory. This application does not impose any restrictions on this.

[0055] The data processing method provided in this application embodiment can be executed by the data processing device 10. Specifically, it obtains the first latitude and longitude data of the data processing device 10 from the database 11, determines the second latitude and longitude data based on the first parameter value in the first direction of the data processing device, and determines the third latitude and longitude data based on the second parameter value in the second direction perpendicular to the first direction of the data processing device. Then, it determines the fourth latitude and longitude data based on the second latitude and longitude data and the third latitude and longitude data. Thus, the geographic grid corresponding to the data processing device can be determined based on the first latitude and longitude data, the second latitude and longitude data, the third latitude and longitude data and the fourth latitude and longitude data, thereby obtaining a more accurate geographic grid.

[0056] In some embodiments, "data processing device" and "geographic grid" are merely names used in the embodiments of this application, and these names do not constitute a limitation on the embodiments of this application. Optionally, "data processing device" may also be called "geographic grid device" or "grid processing device," etc.; "geographic grid" may also be called "geofence" or "geographic mesh," etc., and this application does not impose any limitations on this.

[0057] Please see Figure 2 , Figure 2 This is a flowchart illustrating a data processing method provided in an embodiment of this application. Figure 2 As shown, the data processing method includes, but is not limited to, the following steps S201 to S205.

[0058] S201, Obtain the first latitude and longitude data from the data processing device.

[0059] The first latitude and longitude data can be the latitude and longitude data of the geographical location of the data processing equipment. Optionally, the coordinates of the geographical location of the data processing equipment can be used as the reference coordinates, and the first latitude and longitude data can be the latitude and longitude corresponding to the reference coordinates. Optionally, the reference coordinates can be the coordinates corresponding to the center point of the data processing equipment, or the coordinates corresponding to the center point of the computer room where the data processing equipment is located; this application does not impose any restrictions on this.

[0060] It is understandable that, in determining the geographic grid corresponding to the data processing device, the geographical location of the data processing device can remain unchanged; that is, the reference coordinate point can be a fixed coordinate point. In other words, in determining the geographic grid corresponding to the data processing device, the first latitude and longitude data corresponding to the reference coordinate point can be fixed latitude and longitude data.

[0061] S202, determine the second latitude and longitude data based on the first parameter value in the first direction of the data processing device.

[0062] The first direction can be horizontal, vertical, or any other direction; this application does not impose any restrictions on it. The first direction of the data processing device can be understood as the first direction of the reference coordinate point corresponding to the data processing device. It should be noted that the following example uses a horizontal direction as the first direction and does not constitute a limitation on this application.

[0063] The aforementioned first parameter value can be used to indicate the distance between the data processing device and other coordinate points in a first direction, and the first parameter value can be any numerical value. Optionally, the unit of the first parameter value can be "meters," and this application does not limit this. For example, if the first parameter value is 100 meters, it can indicate that the distance between the data processing device and other coordinate points in the first direction is 100 meters.

[0064] For example, such as Figure 3 As shown, assuming the first direction is horizontal and the first parameter value is 100 meters, the data processing device can determine the latitude and longitude data of other coordinate points (such as the first coordinate point) based on the distance of 100 meters in the horizontal direction of the reference coordinate point corresponding to the data processing device, which is the aforementioned second latitude and longitude data.

[0065] In one implementation, the data processing device can convert first latitude and longitude data into first projected coordinate data using a projected coordinate system; determine first reference projected coordinate data based on the first parameter value in the first direction of the data processing device and the first projected coordinate data; convert the first reference projected coordinate data into first reference latitude and longitude data using a geographic coordinate system; and determine second latitude and longitude data based on the first reference latitude and longitude data.

[0066] The data processing device can convert the first latitude and longitude data into first projected coordinate data through a projected coordinate system, so as to represent the first latitude and longitude data through two-dimensional first projected coordinate data. Then, based on the first parameter value in the first direction of the data processing device (reference coordinate point) and the first projected coordinate data, the first reference projected coordinate data of the reference coordinate point (such as the first reference coordinate point) can be determined, and then the first reference projected coordinate data can be converted into first reference latitude and longitude data through a geographic coordinate system.

[0067] As described above, in the application scenario of this application, the distance between two coordinate points and the arc length of those two coordinate points on the sphere can be considered equal. Therefore, the data processing device can determine the first arc length based on the first latitude and longitude data and the first reference latitude and longitude data. By comparing the first arc length with the first parameter value, the accuracy of the determined reference latitude and longitude data (such as the first reference latitude and longitude data and the second reference latitude and longitude data) can be ensured, and the reference latitude and longitude data with higher accuracy can be determined as the second latitude and longitude data.

[0068] It should be noted that the steps involved in determining the more accurate second latitude and longitude data using the data processing equipment are described in detail below, and will not be repeated here.

[0069] S203, based on the second parameter value in the second direction of the data processing device, determine the third latitude and longitude data; the second direction is perpendicular to the first direction.

[0070] The second direction can be horizontal, vertical, or any other direction; this application does not impose any restrictions on this. In the embodiments of this application, the second direction is perpendicular to the first direction. That is, when the first direction is horizontal, the second direction can be vertical; and when the first direction is vertical, the second direction can be horizontal. It should be noted that the following example using the second direction as vertical does not constitute a limitation on this application.

[0071] The aforementioned second parameter value can be used to indicate the distance between the data processing device and other coordinate points in the second direction, and this second parameter value can be any numerical value. Optionally, the unit of the second parameter value can be "meters," and this application is not limited in this regard. Optionally, the second parameter value can be the same as or different from the first parameter value, and this application is not limited in this regard. For example, if the second parameter value is 100 meters, it can indicate that the distance between the data processing device and other coordinate points in the second direction is 100 meters; if the second parameter value is 200 meters, it can indicate that the distance between the data processing device and other coordinate points in the second direction is 200 meters.

[0072] For example, such as Figure 4 As shown, assuming the second direction is vertical and the second parameter value is 100 meters, the data processing device can determine the latitude and longitude data of other coordinate points (such as the second coordinate point) based on the distance of 100 meters in the horizontal direction of the reference coordinate point corresponding to the data processing device, which is the aforementioned third latitude and longitude data.

[0073] It should be noted that the data processing device determines the relevant content of the third latitude and longitude data based on the second parameter value in the second direction of the data processing device. For details on the determination of the second latitude and longitude data based on the first parameter value in the first direction of the data processing device, please refer to the aforementioned data processing device. This application will not repeat the details here.

[0074] S204, based on the second and third latitude and longitude data, determine the fourth latitude and longitude data.

[0075] Understandably, once the data processing device has determined the second and third latitude and longitude data—that is, once it has determined the first and second coordinate points—it has already identified the three vertices of the geographic raster corresponding to the data processing device. These are the reference coordinate points, the first coordinate point, and the second coordinate point. At this point, the data processing device can determine the fourth latitude and longitude data corresponding to the fourth vertex (such as the third coordinate point) based on these three vertices.

[0076] In one implementation, the data processing device can determine the fourth latitude and longitude data based on the longitude data corresponding to the second latitude and longitude data and the latitude data corresponding to the third latitude and longitude data; and / or, determine the fourth latitude and longitude data based on the latitude data corresponding to the second latitude and longitude data and the longitude data corresponding to the third latitude and longitude data.

[0077] Understandably, if the first direction is horizontal and the second direction is vertical, the data processing device can determine the fourth latitude and longitude data based on the longitude data corresponding to the second latitude and longitude data and the latitude data corresponding to the third latitude and longitude data. In other words, the longitude data in the fourth latitude and longitude data is the same as the longitude data corresponding to the second latitude and longitude data, and the latitude data in the fourth latitude and longitude data is the same as the latitude data corresponding to the third latitude and longitude data.

[0078] Optionally, if the first direction is vertical and the second direction is horizontal, the data processing device can determine the fourth latitude and longitude data based on the latitude data corresponding to the second latitude and longitude data and the longitude data corresponding to the third latitude and longitude data. In other words, the longitude data in the fourth latitude and longitude data is the same as the longitude data corresponding to the third latitude and longitude data, and the latitude data in the fourth latitude and longitude data is the same as the latitude data corresponding to the second latitude and longitude data.

[0079] For example, such as Figure 5 As shown, Figure 5 An exemplary diagram is shown of a geographic raster (such as referred to as the first geographic raster) corresponding to the reference coordinate points of the data processing device. It is understood that... Figure 5 Taking the case where the first parameter value and the second parameter value are the same, i.e., the first geographic raster is a square, does not constitute a limitation on this application. Optionally, if the first parameter value and the second parameter value are different, the first geographic raster can be a rectangle, and this application does not impose any restrictions on this.

[0080] Among them, by Figure 5 It can be seen that the first coordinate point can be a coordinate point in the first direction (i.e., the positive horizontal direction) of the reference coordinate point, the second coordinate point can be a coordinate point in the second direction (i.e., the positive vertical direction) of the reference coordinate point, and the third coordinate point can be a coordinate point in the diagonal direction of the reference coordinate point. Optionally, the third coordinate point can also be a coordinate point of the first coordinate point in the second direction (i.e., the vertical direction), and the third coordinate point can also be a coordinate point of the second coordinate point in the first direction (i.e., the horizontal direction).

[0081] It should be noted that the aforementioned first and second directions are both described using positive directions as examples. Optionally, the first and / or second directions can also be negative directions, and this application does not impose any restrictions on this. In other words, the data processing device can determine, based on the reference coordinate points, such as... Figure 5 This application does not limit the scope of at least one of the first geographic raster 1, first geographic raster 2, first geographic raster 3 and first geographic raster 4 shown.

[0082] S205, based on the first latitude and longitude data, the second latitude and longitude data, the third latitude and longitude data, and the fourth latitude and longitude data, determines the geographic grid corresponding to the data processing equipment.

[0083] As described above, the data processing device can determine the first geographic raster corresponding to the reference coordinate point based on the first latitude and longitude data, the second latitude and longitude data, the third latitude and longitude data, and the fourth latitude and longitude data. It is understood that the data processing device can also determine the second geographic raster corresponding to the first coordinate point based on the determined second latitude and longitude data; and can determine the third geographic raster corresponding to the second coordinate point based on the determined third latitude and longitude data, and so on. This application will not elaborate further on these points.

[0084] In one implementation, the data processing device can determine a first geographic grid based on first latitude and longitude data, second latitude and longitude data, third latitude and longitude data, and fourth latitude and longitude data; determine a second geographic grid based on second latitude and longitude data; determine a third geographic grid based on third latitude and longitude data; determine a fourth geographic grid based on fourth latitude and longitude data; and determine the geographic grid network corresponding to the data processing device based on the first geographic grid, second geographic grid, third geographic grid, and fourth geographic grid.

[0085] It should be noted that after the data processing device determines the first geographic raster, the second geographic raster, the third geographic raster, and the fourth geographic raster, etc., the data processing device can obtain the geographic raster network corresponding to the data processing device based on the first geographic raster, the second geographic raster, the third geographic raster, and the fourth geographic raster, etc., and this application does not impose any restrictions on this.

[0086] The following detailed description uses the example of a data processing device determining a second geographic raster based on second latitude and longitude data. Optionally, the data processing device may determine a third geographic raster based on third latitude and longitude data, and a fourth geographic raster based on fourth latitude and longitude data, etc. For details, please refer to the following description, which will not be repeated here.

[0087] In one implementation, the data processing device can determine fifth latitude and longitude data based on a first parameter value in a first direction of a first coordinate point; the first coordinate point is the coordinate point corresponding to the second latitude and longitude data; determine sixth latitude and longitude data based on a second parameter value in a second direction of the first coordinate point; the second direction is perpendicular to the first direction; determine seventh latitude and longitude data based on the fifth and sixth latitude and longitude data; and determine a second geographic raster based on the second, fifth, sixth, and seventh latitude and longitude data.

[0088] In this application, the first direction of the first coordinate point can be the same as the first direction of the reference coordinate point, and the second direction of the first coordinate point can be the same as the second direction of the reference coordinate point. That is, if the data processing device determines the horizontal direction as the first direction of the reference coordinate point corresponding to the data processing device when determining the first geographic grid, then the data processing device can also determine the horizontal direction as the first direction of the first coordinate point when determining the second geographic grid; similarly, if the data processing device determines the vertical direction as the second direction of the reference coordinate point corresponding to the data processing device when determining the first geographic grid, then the data processing device can also determine the vertical direction as the second direction of the first coordinate point when determining the second geographic grid. This application does not impose any restrictions on this.

[0089] It is understandable that the first parameter value in the first direction of the first coordinate point can be the same as the first parameter value in the first direction of the data processing device, and the second parameter value in the second direction of the first coordinate point can be the same as the second parameter value in the second direction of the data processing device. This ensures that the shapes of the first and second geographic grids determined by the data processing device are the same, thereby obtaining a geographic grid corresponding to the data processing device with a uniform shape.

[0090] It should be noted that the data processing device determines the relevant content of the fifth latitude and longitude data based on the first parameter value in the first direction of the first coordinate. For details on the determination of the second latitude and longitude data based on the first parameter value in the first direction of the data processing device, please refer to the aforementioned data processing device. This application will not repeat the details here.

[0091] For example, suppose the data processing device determines as follows: Figure 5 Following the first geographic raster shown, the data processing device can be based on Figure 5 The first parameter value in the first direction and the second parameter value in the second direction of the first coordinate point in the image are used to determine the second geographic raster. For example... Figure 6 As shown, Figure 6 An exemplary schematic diagram of a second geographic raster is shown. Wherein, by Figure 6 It can be seen that the fourth coordinate point can be a coordinate point in the first direction (i.e., the positive horizontal direction) of the first coordinate point, the fifth coordinate point can be a coordinate point in the second direction (i.e., the positive vertical direction) of the first coordinate point, and the sixth coordinate point can be a coordinate point in the diagonal direction of the first coordinate point.

[0092] Depend on Figure 6 It is understood that the sixth latitude and longitude data determined by the data processing device based on the second parameter value in the second direction of the first coordinate point can be the same as the fourth latitude and longitude data determined by the data processing device based on the second and third latitude and longitude data. In other words, the fifth coordinate point can be the same coordinate point as the third coordinate point, and this application does not impose any restrictions on this.

[0093] Understandably, when determining the first geographic grid, the data processing device can determine the fourth latitude and longitude data based on the second and third latitude and longitude data, that is, determine the coordinate point on the diagonal direction of the reference coordinate point (i.e., the third coordinate point). Optionally, when determining the second geographic grid, the data processing device can also determine the sixth latitude and longitude data based on the second parameter value in the second direction of the first coordinate point, that is, determine the coordinate point in the second direction of the first coordinate point (i.e., the fifth coordinate point).

[0094] It should be noted that the data processing device can determine the fourth and sixth latitude and longitude data using the two methods described above, thereby further determining the accuracy of the latitude and longitude data determined by the two methods. The device can then select the latitude and longitude data with higher accuracy as the latitude and longitude data for that coordinate point, thus improving the accuracy of the geographic grid determined by the data processing device. For example, if the data processing device determines the fourth latitude and longitude data with higher accuracy, it can then select this fourth latitude and longitude data as the latitude and longitude data corresponding to the third and fifth coordinate points. This application does not impose any limitations on this.

[0095] Optionally, the data processing device can also employ a method to determine the fourth latitude and longitude data, or the sixth latitude and longitude data, thereby reducing the computational load on the data processing device, saving energy consumption, and improving computational efficiency. For example, the data processing device can determine the fourth latitude and longitude data corresponding to the third coordinate point during the determination of the first geographic raster, and can directly use the fourth latitude and longitude data during the determination of the second geographic raster, i.e., it does not need to perform the relevant steps for determining the sixth latitude and longitude data. Optionally, the data processing device can also skip the relevant steps for determining the fourth latitude and longitude data during the determination of the first geographic raster, and determine the sixth latitude and longitude data based on the second parameter value in the second direction of the first coordinate point during the determination of the second geographic raster; this application does not limit this.

[0096] Understandably, a data processing device can determine the four geographic grids corresponding to any given coordinate point; that is, the data processing device can determine the four geographic grids corresponding to a first coordinate point. For example... Figure 6 As shown, the data processing device can also determine the first geographic raster 1 and the first geographic raster 4 based on the first coordinate point, and this application does not limit this. Optionally, the data processing device can determine at least one of the second geographic raster 1 and the second geographic raster 2 based on the first coordinate point, and this application does not limit this.

[0097] The data processing device can determine the third, fourth, and other geographic rasters using the above method, and then further determine the corresponding geographic grid for the data processing device based on each geographic raster (such as the first, second, third, and fourth geographic rasters mentioned above). Figure 7 As shown, Figure 7 An exemplary schematic diagram of a geographic raster corresponding to a reference coordinate point of a data processing device is shown.

[0098] In this embodiment, the data processing device acquires first latitude and longitude data, determines second latitude and longitude data based on first parameter values ​​in a first direction, determines third latitude and longitude data based on second parameter values ​​in a second direction perpendicular to the first direction, and determines fourth latitude and longitude data based on the second and third latitude and longitude data. Thus, based on the first latitude and longitude data, as well as the more accurate second, third, and fourth latitude and longitude data, the geographic grid corresponding to the data processing device can be determined, thereby obtaining a more accurate geographic grid.

[0099] Please see Figure 8 , Figure 8 This is a flowchart illustrating a data processing method provided in an embodiment of this application. Figure 8 As shown, the data processing method includes, but is not limited to, the following steps S801 to S815.

[0100] S801, obtain the first latitude and longitude data.

[0101] S802 converts the first latitude and longitude data into the first projected coordinate data through the projected coordinate system.

[0102] S803, based on the first parameter value in the first direction of the data processing device and the first projection coordinate data, determine the first reference projection coordinate data.

[0103] S804 converts the first reference projected coordinate data into first reference latitude and longitude data using a geographic coordinate system.

[0104] It should be noted that the relevant content of steps S801-S804 can be found in [reference needed]. Figure 2 The detailed descriptions in the corresponding embodiments are not repeated here.

[0105] S805, determine the first arc length based on the first reference latitude and longitude data and the first latitude and longitude data.

[0106] Specifically, in the process of the data processing device determining whether the first reference latitude and longitude data is accurate, that is, in determining whether the difference between the first arc length and the first parameter value meets the preset conditions, the following two situations may exist. Among them, the preset conditions may include whether the difference between the first arc length and the first parameter value is less than or equal to a preset precision.

[0107] S806, Check if the difference between the first arc length and the first parameter value is less than or equal to the preset precision. If the difference between the first arc length and the first parameter value is less than or equal to the preset precision (Case 1), then execute S807; if the difference between the first arc length and the first parameter value is greater than the preset precision (Case 2), then execute S808.

[0108] The preset precision can be a pre-set precision value, which can be any value, such as 1 or 1.2. This application does not limit this.

[0109] S807, the first reference latitude and longitude data is determined to be the second latitude and longitude data.

[0110] In other words, if the difference between the first arc length and the first parameter value meets the preset condition (i.e., the difference between the first arc length and the first parameter value is less than or equal to the preset precision), it means that the difference between the first arc length and the first parameter value is within the preset precision, and the data processing device can determine that the first reference latitude and longitude data is the second latitude and longitude data (i.e., the first reference coordinate point is the first coordinate point).

[0111] S808, based on the first reference latitude and longitude data, the first latitude and longitude data, and the first reference projected coordinate data, determine the second reference projected coordinate data.

[0112] It is understandable that if the difference between the first arc length and the first parameter value does not meet the preset conditions, that is, if the difference between the first arc length and the first parameter value is greater than the preset precision, it means that the difference between the first arc length and the first parameter value is outside the preset precision. At this time, the data processing device can correct the first reference projection coordinate data to obtain the second reference projection coordinate data of the corrected reference coordinate point (such as the second reference coordinate point). Then, the second reference latitude and longitude data can be determined through the second reference projection coordinate data, and further, it can be determined whether the determined second reference latitude and longitude data is accurate.

[0113] It should be noted that, in the embodiments of this application, the data processing device can correct the first reference projection coordinate data by superimposing the difference between the first arc length and the first parameter value onto the first reference projection coordinate data, thereby obtaining the corrected second reference projection coordinate data. It is understood that, when the first reference coordinate point is a coordinate point in the horizontal direction of the reference coordinate point, the data processing device can superimpose the difference between the first arc length and the first parameter value onto the X-axis data of the first reference projection coordinate data; this application does not impose any limitations on this.

[0114] Optionally, if the first reference coordinate point is a coordinate point in the vertical direction of the reference coordinate point, the data processing device can superimpose the difference between the first arc length and the first parameter value onto the Y-axis data of the first reference projected coordinate data. Optionally, if the first reference coordinate point is a coordinate point in other directions (such as non-horizontal or non-vertical directions) of the reference coordinate point, the data processing device can distribute the difference between the first arc length and the first parameter value, and superimpose the distributed values ​​onto the X-axis and Y-axis data of the first reference projected coordinate data respectively. This application does not impose any limitations on this.

[0115] S809 converts the second reference projected coordinate data into second reference latitude and longitude data using a geographic coordinate system.

[0116] S810 determines the second arc length based on the second reference latitude and longitude data and the first latitude and longitude data.

[0117] In this embodiment, when the data processing device determines whether the difference between the second arc length and the first parameter value meets a preset condition, the preset condition may include whether the absolute value of the difference between the second arc length and the first parameter value is less than the absolute value of the difference between the first arc length and the first parameter value, and whether the difference between the second arc length and the first parameter value is less than or equal to a preset precision. That is, the data processing device not only needs to determine whether the difference between the second arc length and the first parameter value is within the preset precision, but also needs to determine whether the calculated difference between the second arc length and the first parameter value is gradually converging.

[0118] S811, check if the absolute value of the difference between the second arc length and the first parameter value is less than the absolute value of the difference between the first arc length and the first parameter value. If the absolute value of the difference between the second arc length and the first parameter value is greater than or equal to the absolute value of the difference between the first arc length and the first parameter value, then execute S812; if the absolute value of the difference between the second arc length and the first parameter value is less than the absolute value of the difference between the first arc length and the first parameter value, then execute S813.

[0119] S812, determine the first reference latitude and longitude data as the second latitude and longitude data.

[0120] It should be noted that if the difference between the second arc length and the first parameter value does not meet the preset conditions, such as if the absolute value of the difference between the second arc length and the first parameter value is greater than or equal to the absolute value of the difference between the first arc length and the first parameter value, it means that the calculated difference between the second arc length and the first parameter value has not converged, that is, the difference (error) has become larger. In this case, the data processing device can determine that the first reference latitude and longitude data before correction is the second latitude and longitude data.

[0121] It is understandable that when the absolute value of the difference between the second arc length and the first parameter value is greater than or equal to the absolute value of the difference between the first arc length and the first parameter value, the difference between the second arc length and the first parameter value is greater than the preset precision, which will not be elaborated further in this application.

[0122] S813, Check if the difference between the second arc length and the first parameter value is less than or equal to the preset precision. If the difference between the second arc length and the first parameter value is less than or equal to the preset precision, then execute S814; if the difference between the second arc length and the first parameter value is greater than the preset precision, then execute S815.

[0123] S814, the second reference latitude and longitude data is determined to be the second latitude and longitude data.

[0124] Understandably, if the difference between the second arc length and the first parameter value meets the preset conditions, that is, the absolute value of the difference between the second arc length and the first parameter value is less than the absolute value of the difference between the first arc length and the first parameter value, and the difference between the second arc length and the first parameter value is less than or equal to the preset precision, then the data processing device can determine that the second reference latitude and longitude data is the second latitude and longitude data (that is, the second reference coordinate point is the first coordinate point).

[0125] S815, based on the second reference latitude and longitude data, the first latitude and longitude data, and the second reference projected coordinate data, determines the third reference latitude and longitude data, and further determines whether the third reference latitude and longitude data is accurate.

[0126] If the difference between the second arc length and the first parameter value does not meet the preset conditions, such as the absolute value of the difference between the second arc length and the first parameter value being less than the absolute value of the difference between the first arc length and the first parameter value, and the difference between the second arc length and the first parameter value being greater than the preset precision, it indicates that the calculated difference between the second arc length and the first parameter value is convergent. However, if the difference between the second arc length and the first parameter value is outside the preset precision, the data processing device can correct the second reference projection coordinate data to obtain the corrected reference projection coordinate data (such as the third reference projection coordinate data). Then, the reference latitude and longitude data (such as the third reference latitude and longitude data) can be determined through the third reference projection coordinate data, and further, it can be determined whether the determined third reference latitude and longitude data is accurate.

[0127] It is understandable that the process by which the data processing device determines whether the third reference latitude and longitude data is accurate can be referred to the process by which the data processing device determines whether the second reference latitude and longitude data is accurate, and will not be repeated here.

[0128] For example, assuming a preset accuracy of 1 meter, a horizontal first direction, a first parameter value of 100 meters, a geographic coordinate system of WGS84, and a Gauss-Krüger projection, the data processing device can determine the second latitude and longitude data using a calculation tool (such as PROJ) based on the first latitude and longitude data corresponding to the reference coordinate point and the first parameter value. The specific calculation process and correction data are shown in the table below:

[0129]

[0130]

[0131] Table 1 shows the calculation example data in the process of determining the second latitude and longitude data.

[0132] As shown in Table 1, by superimposing the difference between the arc length and the first parameter value onto the X-axis data of the reference projection coordinate data, the data processing device can gradually reduce the difference between the arc length and the first parameter value, and finally control the difference between the arc length and the first parameter value within the range of preset accuracy. Thus, after three iterations of correction, the second latitude and longitude data is determined, thereby improving the accuracy of the second latitude and longitude data determined by the data processing device.

[0133] It should be noted that, Figure 8 The corresponding embodiments are the same as those described above. Figure 2 The detailed steps for determining the second latitude and longitude data in the corresponding data processing method embodiments are based on the same concept and bring the same technical effects. For the specific principles, please refer to the detailed description in the aforementioned data processing method embodiments. This application will not repeat them here.

[0134] In this embodiment of the application, during the process of determining the second latitude and longitude data based on the first parameter value in the first direction of the data processing device, the data processing device continuously iterates and corrects the reference projection coordinate data, such as determining the first reference projection coordinate data, the second reference projection coordinate data, and the third reference projection coordinate data. This process ensures that the difference between the arc length and the first parameter value meets the preset conditions, and the reference latitude and longitude data corresponding to meeting the preset conditions is determined as the second latitude and longitude data, thereby obtaining more accurate second latitude and longitude data and improving the accuracy of the subsequently determined first geographic grid.
