[0034] In order to make the purpose, technical scheme and advantages of the embodiments of the present disclosure clearer, the technical scheme in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all of the embodiments. The components of the embodiments of the present disclosure generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present disclosure provided in the drawings is not intended to limit the scope of the present disclosure for protection, but merely represents the selected embodiments of the present disclosure. Based on the embodiments of the present disclosure, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present disclosure.

[0035] It should be noted that in the technical solution of the present invention, the collection, use, storage, sharing and transfer of user personal information involved are in compliance with the provisions of relevant laws and regulations, and it is necessary to inform the user and obtain the user's consent or authorization. When applicable, the user's personal information is de-identified and / or anonymized and / or encrypted.

[0036] Research has found that the base map is the basic layer in the visualization display, which is used to provide basic information and background reference for the top layer of the display, and is very important for visualization and information communication. For example, in the field of map services, the map base map is used to provide basic background information of the map, such as land, water, roads, boundaries, etc.; common map base maps include satellite images, topographic maps, street maps, etc. Base map loading can be achieved by using the service interface provided by the base map provider. Developers can call these interfaces to request base map images or vector data and display them on the application canvas to provide corresponding basic information and reference background.

[0037] However, a display instance can often only load one basemap. If you want to load a lock basemap or overlay multiple basemaps to form a new display style, you usually need to create multiple display instances. It is impossible to integrate multiple basemaps on one display instance, let alone integrate basemaps between different basemap providers. Moreover, the basemap loaded by a display instance can often only be of a fixed style and cannot be applied to the display styles of different pages. If you want to customize the basemap style or integrate multiple basemaps to form a new basemap, the existing technology usually requires obtaining the basemap data and then publishing a new basemap to achieve this. Not only can ordinary users not obtain the basemap data, but the new basemap obtained in this way is also of a fixed style and still cannot adapt to the switching of multiple display styles.

[0038] Based on the above research, the disclosed embodiment provides a base map processing method, which can obtain pixel data and index values ​​of multiple original tiles in the initial base map; adjust the pixel data of multiple original tiles based on the image processing method selected by the user to obtain multiple target tiles; and draw an image corresponding to each target tile based on the index value to obtain a target base map. Thus, each original tile in the initial base map is processed corresponding to the processing method selected by the user, and redrawn into the processed target base map, thereby realizing the style conversion of the base map and improving the flexibility and adaptability of the base map service. In addition, when there are at least two initial base maps, after adjusting the pixel data of multiple original tiles and before obtaining multiple target tiles, it also includes: determining the position information of each original tile in the corresponding initial base map based on the index value; according to the adjusted pixel data, the original tiles with consistent position information in different initial base maps are merged to obtain multiple merged target tiles; wherein the number of the merged multiple target tiles is equal to the number of the original tiles in each initial base map. Thus, the fusion of multiple base maps can be realized, further improving the flexibility and adaptability of the base map service. In addition, the basemap service link in the embodiment of the present disclosure may be user-defined, thereby enabling basemap fusion between different basemap providers.

[0039] The raising of the above problems and the solutions are the results obtained by the inventor after practice and careful research. The discovery process of the above problems and the solutions proposed for the above problems should be the contributions made by the inventor to the present disclosure during the disclosure process.

[0040] The technical solutions in the present disclosure will be clearly and completely described below in conjunction with the drawings in the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all of the embodiments. The components of the present disclosure generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present disclosure provided in the drawings is not intended to limit the scope of the present disclosure claimed for protection, but merely represents the selected embodiments of the present disclosure. Based on the embodiments of the present disclosure, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present disclosure.

[0041] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0042] To facilitate understanding of this embodiment, a base map processing method disclosed in the embodiment of the present disclosure is first introduced in detail. The execution subject of the base map processing method provided in the embodiment of the present disclosure is generally a computer device with certain computing capabilities, and the computer device includes, for example: a terminal device or a server or other processing device, and the terminal device can be a user equipment (User Equipment, UE), a mobile device, a user terminal, a terminal, a cellular phone, a cordless phone, a personal digital assistant (Personal Digital Assistant, PDA), a handheld device, a computing device, a vehicle-mounted device, a wearable device, etc. In some possible implementations, the base map processing method can be implemented by a processor calling a computer-readable instruction stored in a memory.

[0043] See also Figure 1 As shown, it is a flow chart of the base map processing method provided in the embodiment of the present disclosure. It should be noted that the following description of the base map processing method provided in the embodiment of the present disclosure is described by taking the map base map service scenario as an example, which does not constitute an improper limitation on the present invention. The base map processing method provided by the present invention can be applied to any scenario such as map service, data visualization, computer graphics, etc.; the method includes S101~S103, wherein:

[0044] S101: Obtain pixel data and index values ​​of multiple original tiles in the initial base map.

[0045] In the disclosed embodiment, the index value is a parameter used to identify and locate multiple tiles, which may include a horizontal index, a vertical index, and a zoom level. In a specific implementation, a combination of x, y, and z may be used as the index value of each tile; wherein x may be used to represent the index or column number in the horizontal direction, which may usually be counted from 0 in an incrementing manner from left to right; y may be used to represent the index or row number in the vertical direction, which may usually be counted from 0 in an incrementing manner from top to bottom; and z may be used to represent the zoom level or level of the tile, wherein a smaller z value may be used to represent a larger base map range, and a larger z value may represent a more detailed base map range.

[0046] In the embodiment of the present disclosure, the execution subject of the embodiment of the present disclosure may request a base map service from a base map provider, and then receive the base map returned by the base map provider. Specifically, if the requested base map exceeds the processing capacity of a single request or the limitation of network transmission, the base map provider, in response to the request, returns a plurality of slices corresponding to the initial base map to the execution subject of the embodiment of the present disclosure. Since the size and shape of the slices here may be divided according to the design and implementation method of the base map service provider, when the execution subject of the embodiment of the present disclosure receives the base map returned by the base map provider, it may re-divide it according to its own needs to obtain a plurality of original tiles.

[0047] In a specific implementation, when the received initial base map is a complete base map, the executing body of the embodiment of the present disclosure can segment it according to the needs, and the visualization capabilities and needs of the current display page, data transmission efficiency, base map boundaries and other aspects can be used as references when segmenting. When the received original base map is a base map segmented by the base map provider, it can be re-segmented to adapt it to the tile specifications required by the embodiment of the present disclosure. It should be noted that when the number of initial base maps is greater than or equal to two, due to the differences in size, data volume and other aspects of different base maps, in order to facilitate subsequent processing, multiple base maps can be standardized, and then each initial base map can be segmented into the same number of original tiles.

[0048] In the disclosed embodiment, before obtaining the pixel data and index values ​​of the plurality of original tiles in the initial base map, the method further includes: obtaining a base map service link defined by a user, and calling the initial base map corresponding to the base map service link.

[0049] In a specific implementation, the user can customize the base map service link, where the base map service link can be one or more; when there is one base map service link, the base map can be subsequently subjected to operations such as saturation, brightness, contrast, hue and blur; when there are at least two base map service links, the base map can be subsequently subjected to operations such as overlay, superposition, blending and difference. It should be noted that the base map service link here can be provided by the user himself, or it can be provided by the execution subject of the embodiment of the present disclosure and selected by the user. In addition, when there are at least two base map service links, the user can also be instructed to select the service link corresponding to the primary initial base map and the service link corresponding to the secondary initial base map. This will help to adjust the corresponding degree of different initial base maps according to the primary and secondary levels during the subsequent specific processing.

[0050] S102: Based on the image processing method selected by the user, pixel data of the plurality of original tiles are adjusted to obtain a plurality of target tiles.

[0051] In this step, the user can select or input a processing method for the initial base map in the current display page to adjust the pixel data of the initial base map.

[0052] In an embodiment of the present disclosure, when the number of initial base maps is one, the user can choose to perform operations such as saturation, brightness, contrast, hue and blur. In a preferred implementation, multiple original tiles of the initial base map can be adjusted in parallel to improve processing efficiency. Several common situations are exemplified below. It should be noted that the modification of pixel data here can be based on a numerical value set by the user or based on the visualization effect of the currently displayed page; and the following processing method for the original tiles is only exemplified as a possible implementation method of the embodiment of the present disclosure, and does not constitute an improper limitation on the present invention.

[0053] Exemplarily, when the processing method selected by the user is to adjust the saturation, each original tile image can be converted from the RGB color space to the HSV (Hue, Saturation, Value) color space, and then the data of the saturation channel can be modified. After the modification is completed, the image can be converted back to the RGB color space.

[0054] For example, when the processing method selected by the user is to adjust the brightness, the pixel data of each original tile can be adjusted by linear transformation. Specifically, when the background brightness needs to be increased, the RGB channel corresponding to each pixel can be increased by a constant; otherwise, it can be reduced by a constant.

[0055] For example, when the processing method selected by the user is to adjust the saturation, the pixel data of each original tile can be adjusted by linear transformation. Specifically, when the contrast of the base map needs to be increased, the pixel value of each original tile can be stretched along the grayscale direction to increase the difference between adjacent pixel values; otherwise, the pixel value of each original tile can be compressed along the grayscale direction to reduce the difference between adjacent pixel values.

[0056] Exemplarily, when the processing method selected by the user is to adjust the hue, each original tile image can be converted from the RGB color space to the HSV color space, and then the data of the hue channel can be modified as required. After the modification is completed, the image can be converted back to the RGB color space.

[0057] Exemplarily, when the processing method selected by the user is blur, each original tile can be blurred according to a preset blur method, such as Gaussian blur, mean blur, median blur, etc. Taking Gaussian blur as an example, the size of the blur kernel can be adjusted according to the blur processing degree set by the user. After determining the size of the blur kernel, a Gaussian kernel can be constructed and applied to each original tile. For each pixel in the tile, the surrounding pixels are convolved with the Gaussian kernel to calculate the blurred pixel data. In this process, the boundary pixel processing method of the original tiles located at the boundary of the base map also needs to be considered, such as filling the boundary pixel value, using mirroring or copying the boundary pixels, etc., to ensure that the convolution operation can be correctly applied to the entire base map.

[0058] It should be noted that the processing of an initial base map may also include a variety of processing methods such as brightness, sharpening, color temperature, and hue, which will not be described in detail here.

[0059] In another possible implementation, when the number of initial base maps is greater than or equal to two, the user can choose to perform processing such as overlay, superposition, blending and difference. As described above, when processing at least two initial base maps, multiple original tiles of different base maps can also be processed in parallel to improve processing efficiency.

[0060] In an embodiment of the present disclosure, when there are at least two initial base maps, before obtaining multiple target tiles, it also includes: based on the index value, determining the position information of each original tile in the corresponding initial base map; according to the adjusted pixel data, merging the original tiles with consistent position information in different initial base maps to obtain multiple fused target tiles; wherein the number of the multiple fused target tiles is equal to the number of original tiles in each initial base map.

[0061] In a specific implementation, the correspondence between the original tiles in different base maps can be determined based on the index value before or after adjusting the pixel data of the original tiles according to the specific processing method. For example, when the processing method is positive overlay, the specific processing steps are to multiply the pixel values ​​of the original tiles with the same position information in different base maps to achieve the effect of color mixing. In this case, it is necessary to determine the correspondence between the original tiles in different base maps before adjusting the pixel data. When the processing method is transparency overlay, the pixel data of each initial base map can be adjusted according to the set transparency, and then the corresponding tiles can be overlaid. In this case, the correspondence between the original tiles in different base maps can be determined after adjusting the pixel data.

[0062] It should be noted that, since the initial base map has been segmented according to standardized specifications when it is received, and an equal number of original tiles are obtained for each initial base map, the number of target tiles after fusion is also equal to the number of original tiles of each initial base map.

[0063] Exemplarily, when the processing method selected by the user is mixing, each corresponding pixel point in the corresponding multiple original tiles can be mixed according to a set weight to achieve a highlight or shadow effect.

[0064] In the embodiments of the present disclosure, the processing methods for at least two initial base maps may also include superposition, difference, screening, etc., which will not be described in detail below and do not constitute an improper limitation on the present invention. It should be emphasized that the above-mentioned specific processing methods, whether for one initial base map or at least two initial base maps, are all illustrated as a possible implementation method and do not constitute an improper limitation on the present invention. In addition to the implementation methods for different processing methods described above, any feasible method may be used for implementation. In actual applications, the method is based on the ability to achieve its functions, and the present invention does not make specific limitations on this.

[0065] S103: Based on the index value, draw an image corresponding to each of the target tiles to obtain a target base map.

[0066] In this step, after the corresponding target tile is obtained, the image corresponding to each target tile can be drawn on the canvas provided by the execution subject of the embodiment of the present disclosure according to the index value corresponding to each target tile to obtain the final target base map.

[0067] In the disclosed embodiment, drawing an image corresponding to each of the target tiles to obtain a target base map includes: converting the drawn image into a string, assigning the string to a source attribute corresponding to the original tile image to obtain the target base map.

[0068] In a specific implementation, the image in the canvas can be converted into a Base64-encoded string, and the string is assigned to the source attribute corresponding to the original tile image, so that the processed target base map can be displayed in the current visualization page.

[0069] In the disclosed embodiment, a base map setting page may also be provided, and the initial base map and the current target base map may be displayed in a partial area of ​​the page to assist the user in previewing the style of the final target base map in real time.

[0076] According to the adjusted pixel data, original tiles with consistent position information in different initial base maps are fused to obtain a plurality of fused target tiles; wherein the number of the plurality of fused target tiles is equal to the number of original tiles in each initial base map.
