Example one

Fig. 1 is a flowchart of an image processing method according to an embodiment of the present invention, where the embodiment is applicable to a situation where layers in a geographic information system are processed and an image to be displayed is imported into the processed layers to obtain a target display image, the method may be executed by an image processing apparatus, the image processing apparatus may be implemented in a form of hardware and/or software, and the image processing apparatus may be configured in a computing device that can execute the image processing method.

As shown in fig. 1, the method includes:

s110, acquiring at least one piece of element information to be used associated with the image to be displayed, and generating a layer to be displayed according to each piece of element information to be used.

The image to be displayed can be understood as an image corresponding to the corresponding geographic information when geographic information query is performed based on the GIS software. The element information to be used may be understood as at least one of information associated with the image to be displayed, position information of an area to be displayed where the element information to be used is included in the image to be displayed, and image display attribute information, for example, a user may determine the area to be displayed by using the element information to be used, such as geographical position information of the area to be displayed, and may also define display attributes of the image to be displayed, for example, a coordinate system of the image to be displayed may be a longitude and latitude coordinate system or a mars coordinate system, or another coordinate system. The layer to be displayed can be understood as a transparent data layer, the layer to be displayed can be associated with each element information to be used, and the layer to be displayed is set according to each element information to be used so as to determine the layer attribute of the layer to be displayed.

Specifically, when the user queries the geographic image information based on the GIS software, the user may input at least one piece of information of the to-be-used element associated with the to-be-displayed image in the GIS software, for example, in an editing control of a display interface based on the GIS software, input an image storage location, image information, layer attributes, and a coordinate system used by the to-be-displayed image corresponding to the to-be-displayed image. And calling a transparent layer in the GIS software, and associating each element information to be used with the transparent layer to obtain a layer to be displayed corresponding to the image to be displayed.

Optionally, the obtaining at least one to-be-used element information associated with the image to be displayed, and generating the layer to be displayed according to each to-be-used element information includes: according to the image identification of the image to be displayed, at least one piece of element information to be used associated with the image identification is called from an element information repository; and processing each element information to be used based on layer generation software to obtain a layer to be displayed corresponding to the image to be displayed.

The element information repository may be understood as a database for storing element information corresponding to an image to be displayed. The image identifier may be understood as identifying information corresponding to the image to be displayed, so as to determine the element information to be used corresponding to the image to be displayed according to the image identifier. The layer generation software may be understood as software for generating a layer to be displayed, for example, a GIS Portal platform, and may be configured to enable a user to obtain shared layer data.

Specifically, according to an image identifier of an image to be displayed, corresponding element information to be used is called from an element information repository, and each element information to be used is input into layer generation software, so that each element information to be used is processed based on the layer generation software, and a layer to be displayed is obtained.

And S120, determining a to-be-used slicing scheme corresponding to the layer to be displayed according to the to-be-used scaling corresponding to the layer to be displayed.

In practical application, in order to show the image to be displayed to the user more clearly, the image to be displayed may be zoomed, and the corresponding image to be displayed may be retrieved according to the zoom ratio input by the user. It can be understood that the generation of the image to be displayed is related to the layer to be displayed, that is, by adjusting the scaling of the layer to be displayed, the image to be displayed is processed based on the adjusted layer to be displayed, and the image to be displayed with the corresponding scaling can be obtained.

The scaling to be used may be understood as a scale for adjusting the layer to be displayed. The to-be-used slicing scheme may be understood as a slicing scheme corresponding to a to-be-used scaling, and illustratively, the to-be-displayed image layer may be sliced into 4 parts, 16 parts, 64 parts, or the like based on different to-be-used slicing schemes.

In the technical scheme, determining a to-be-used slicing scheme corresponding to a layer to be displayed according to a to-be-used scaling corresponding to the layer to be displayed includes: inputting a to-be-used scaling corresponding to a to-be-displayed layer in a scaling editing control in a target control interface; and determining a slicing scheme to be used corresponding to the image layer to be displayed according to the scaling to be used.

The target control interface can be understood as a control interface of GIS software, the control interface comprises at least one scaling control, and a user can input the scaling to be used in each scaling editing control according to actual requirements.

Specifically, a user may input a corresponding to-be-used scaling through the target control interface to perform scaling processing on the to-be-displayed layer based on each to-be-used scaling, so as to obtain at least one hierarchical to-be-displayed layer. Further, a to-be-used slicing scheme corresponding to each to-be-used scaling is determined, so that the to-be-displayed image layer of the corresponding level is sliced based on each to-be-used slicing scheme.

Illustratively, the number of the to-be-used scaling ratios is 3, and scaling processing is performed on the to-be-displayed layers based on each to-be-used scaling ratio, so that layers to be displayed corresponding to each to-be-used scaling ratio, that is, layers to be displayed of 3 levels can be obtained. According to the scaling to be used corresponding to each level, the slicing scheme to be used corresponding to the layer to be displayed of each level can be determined. Wherein the slicing scheme to be used matches the scaling to be used of the respective level.

And S130, slicing the corresponding layer to be displayed based on each slicing scheme to be used to obtain at least one group of tile data to be used corresponding to each layer to be displayed.

The tile data to be used may be understood as rectangular data of a block into which a layer to be displayed is cut.

Specifically, the to-be-used slicing schemes corresponding to layers to be displayed at different levels are different, and the layers to be displayed at the corresponding levels are called and sliced to obtain the to-be-used tile data corresponding to each layer to be displayed. In other words, the tile data corresponding to the same layer to be displayed is used as a set of tile data to be used.

In practical application, based on each slicing scheme to be used, slicing the corresponding layer to be displayed to obtain at least one group of tile data to be used corresponding to each layer to be displayed, including: determining a current layer to be displayed corresponding to the current slicing scheme to be used and determining a scale to be used between the current layer to be displayed and an original layer to be displayed of an image to be displayed aiming at each slicing scheme to be used; and adjusting the slicing parameters of the layer slicing management tool based on the scale to be used, so as to perform slicing processing on the current layer to be displayed based on the adjusted layer slicing management tool, and obtain corresponding tile data to be used.

Each to-be-used slicing scheme can be used as a current to-be-used slicing scheme, and the current to-be-used slicing scheme can be understood as a scheme for slicing the layer to be displayed at the current moment. The scale to be used may be understood as a scale determined according to a scaling to be used corresponding to the current layer to be displayed, and is used to cut the corresponding layer to be displayed. The original layer to be displayed may be understood as a layer to be displayed that is not sliced. The layer slicing management tool may be understood as a tool for slicing a layer to be displayed, for example, a slice cache plug-in installed in GIS software. The slicing parameter may be understood as a parameter for slicing the layer to be displayed, for example, the number of slices to be performed on the layer to be displayed.

Specifically, for example, one of the to-be-used slicing schemes is taken as the current to-be-used slicing scheme, and the current to-be-used slicing scheme corresponding to the current to-be-displayed layer is called according to the to-be-used scaling corresponding to the current to-be-displayed layer. Based on the current to-be-used slicing scheme, a to-be-used scale between the current to-be-displayed layer and the original to-be-displayed layer of the to-be-displayed image can be determined, so that the slicing parameter corresponding to the current to-be-displayed layer is determined based on the to-be-used scale. By adjusting the slice parameters in the layer slice management tool, the current layer to be displayed can be sliced to obtain the tile data to be used corresponding to the current layer to be displayed.

And S140, when the image display instruction is received, determining target tile data from at least one group of tile data to be used based on the display information in the image display instruction, generating a target display image based on the target tile data, and displaying the target display image.

The image display instruction may be understood as an instruction for displaying an image to be displayed, such as a jump link. The display information may be understood as image display information corresponding to an image to be displayed, such as an image display area, a display scale, a display hierarchy, and the like. The target tile data may be understood as tile data corresponding to an image to be displayed corresponding to the image display instruction. The target display image may be understood as an image to be displayed corresponding to the image display instruction.

Specifically, when a user can query a geographic image based on a GIS Portal in the server, the user can input a map name and the like of a corresponding geographic area, so as to retrieve corresponding image information from the local resource storage module according to information such as the map name and the like, and perform corresponding processing on the image information at the local resource storage module to obtain at least one to-be-used tile data, so as to determine target tile data from at least one group of to-be-used tile data, and directly send the obtained target tile data to the server for viewing.

Optionally, determining the target tile data from at least one set of tile data to be used based on the display information in the image display instruction, includes: analyzing the image display instruction to obtain display information corresponding to the layer to be displayed; determining tile data to be used corresponding to the display information from at least one set of tile data to be used; and determining the tile data to be used as target tile data, generating a target display image based on the target tile data, and displaying.

Illustratively, the display information in the image display instruction is an image to be displayed corresponding to the 2 nd level, the scaling is 80%, and the display area is an a area in the geographic image. According to the display information, a layer to be displayed corresponding to the image to be displayed, that is, a layer to be displayed at the 2 nd level with a scaling of 80% may be called. And slicing the layer according to the to-be-used slicing scheme corresponding to the to-be-displayed layer to obtain corresponding to-be-used tile data serving as target tile data, and generating and displaying a target display image based on the target tile data.

Optionally, determining the tile data to be used as the target tile data, so as to generate and display a target display image based on the target tile data, including: determining a layer to be displayed corresponding to the target tile data as a target display layer; and importing the target tile data into a target display layer, generating a target display image and displaying the target display image.

Wherein, the target display layer can be understood as a layer to be displayed corresponding to the target tile data.

Specifically, a target display layer can be determined according to the target tile data, and the target tile data is imported into the target display layer based on the tile data import software, so that a target display image can be generated. And after the target display image is obtained, sending the target display image to a server so as to display the target display image based on a display interface of the server.

The method has the advantages that the image layer to be displayed is processed based on the local resource storage module, and after the target tile data and the target display layer corresponding to the target tile data are determined, the target tile data are imported into the target display layer to obtain the target display image. That is to say, the processing of the target display image is processed in the local resource storage module, and the processed target display image is directly sent to the server for display, so that the problem that the image display is incomplete when the image layer and the image are processed based on the server can be avoided.

According to the technical scheme, at least one piece of element information to be used associated with the image to be displayed is obtained, the layer to be displayed is generated according to the element information to be used, and the element information to be used is processed according to the layer generation software, so that the layer to be displayed corresponding to the image to be displayed is obtained. Determining a to-be-used slicing scheme corresponding to the to-be-displayed layer according to the to-be-used scaling corresponding to the to-be-displayed layer, determining a corresponding level of to-be-displayed layer according to the to-be-used scaling, and determining a corresponding to-be-used slicing scheme, so as to slice the corresponding level of to-be-displayed layer based on each to-be-used slicing scheme. And carrying out slicing processing on the corresponding layers to be displayed based on each slicing scheme to be used to obtain at least one group of tile data to be used corresponding to each layer to be displayed. According to different scales to be used, the tile data to be used obtained by slicing the layer to be displayed by the slicing scheme to be used are different, and the tile data to be used corresponding to the layer to be displayed at the same level is used as a group of tile data to be used. When an image display instruction is received, determining target tile data from the at least one group of tile data to be used based on display information in the image display instruction, generating a target display image based on the target tile data, displaying, determining the target tile data from the at least one group of tile data to be used according to information such as display hierarchy, display area and display proportion in the display information, determining a target display layer corresponding to the target tile data, importing the target tile data into the target display layer, obtaining a target display image, and displaying. The problems that the slice processing efficiency of the image layer data is low, the occupied space is large, and the image is incomplete when the image layer is lost are solved, the image layer slice processing efficiency is improved, the image layer storage space is reduced, and meanwhile the integrity of image layer processing is guaranteed, so that the image can be displayed completely.

Example two

In a specific example, as shown in fig. 2, in order to ensure data accuracy and improve processing efficiency, a user may save the arranged data thematic layers in the GIS software as data types that can be distributed in the GIS Portal. In order to avoid processing failure caused by too large data volume and too long processing time, the alternative storage is selected as an off-line service definition instead of direct processing and releasing. The concrete mode is as follows:

1.1 selecting the "share" function in the toolbar

1.2 choosing "Web layer" in the share "

1.3, selecting another storage as an offline service definition from the "release Web layer", "overlay Web layer" and "another storage as offline service definition" under the Web layer, and storing the thematic layer data as sd files (that is, storing the thematic layer data in the local resource storage module). When sd is stored, the coordinate system set in the current thematic layer should be selected in the "configuration".

That is to say, a plurality of thematic image layers are pre-stored in the local resource storage module, for example, image layers with different image layer attributes, different display areas, and different image categories can be used as one thematic image layer, when a user needs to call a corresponding image layer, and input image layer information (i.e., element information to be used) corresponding to the required image layer, and generate an image layer to be displayed according to each element information to be used.

As shown in FIG. 3, in order to use the service in Web GIS, the service layer is generated through GIS Portal for the storage and reading of tile data of the following thematic layer. (in this step, only data is uploaded in the portal and services are created but not sliced yet, preview operation cannot be performed in "online mapping" in the portal, and subsequent operations such as slice uploading are required to obtain complete tile data in the service center.) specific steps are as follows:

2.1 selecting "personal hub" in GIS Portal "

2.2 click on personal center and select "My Contents" in the corresponding interface "

2.3 after setting up the folder for storing the layer service during publishing, click the 'add' above "

And 2.4, selecting local resources in the adding process, and distributing the sd file (namely, the layer to be displayed) which is locally stored in the step 1.3 to a GIS Portal to generate thematic layer service. (the step is only to upload data and create services in the portal but not to slice, and can not perform preview operation in the online drawing in the portal, and the whole tile data can be acquired in the service center only by performing operations such as subsequent slice uploading, etc.)

On the basis of the scheme, a user inputs image information (namely element information to be used) corresponding to an image to be displayed through a server, for example, image identification, a storage path and the like of the image to be displayed are included, so that the corresponding image to be displayed is determined from a local resource storage module, and an image layer to be displayed is generated according to the element information to be used associated with the image to be displayed.

Further, the user may select a coordinate system required to be used with the image to be displayed, and input a to-be-used scaling corresponding to the layer to be displayed based on a scaling edit control in the target control interface, so as to determine a to-be-used slicing scheme corresponding to the layer to be displayed according to the to-be-used scaling, see fig. 4. For example, taking the current layer to be displayed as an example, the layer to be displayed is sliced according to a management slice caching tool (i.e., a layer slicing management tool) in the GIS software, specifically, a to-be-used scale between the current layer to be displayed and the original layer to be displayed may be determined, a slicing parameter of the layer management tool is determined based on the to-be-used scale, and the layer to be displayed is sliced based on the adjusted layer slicing management tool, so as to obtain at least one set of tile data to be used.

Illustratively, the scale ratios to be used are shown in the following table:

scale grade	Proportional scale	Space required for slicing	Scale grade	Proportional scale	Space required for slicing
						A1	1:B1	C1	A11	1:B11	C11
A2	1:B2	C2	A12	1:B12	C12
						A3	1:B3	C3	A13	1:B13	C13
A4	1:B4	C4	A14	1:B14	C14
						A5	1:B5	C5	A15	1:B15	C15
A6	1:B6	C6	A16	1:B16	C16
						A7	1:B7	C7	A17	1:B17	C17
A8	1:B8	C8	A18	1:B18	C18
						A9	1:B9	C9	A19	1:B19	C19
A10	1:B10	C10	A20	1:B20	C20

Wherein, the scale level is A, B is the actual distance, and C is the slice size. Among them, B2=2B1, B3=2b2=4b1 \8230, 8230, C2=4C1, C3=4c2= 1692 \8230, 8230and so on.

Further, different to-be-used scaling ratios correspond to different to-be-used slicing schemes, a current to-be-displayed layer corresponding to the to-be-processed layer is determined according to the to-be-used scaling ratio, and the current to-be-used slicing scheme corresponding to the current to-be-displayed layer is called.

For example, if the scale level of the requirement is a10 to a16, a10 and a16 are contents that the thematic map layer data tile must contain; the slice levels a11, a12, a13, a14, and a15 are non-necessarily inclusive. Assuming that the slice definition is 1,3,5 \8230;, the desired slice levels are a10, a12, a14 and a16, and the desired slice space is a10+ a12+ a14+ a16= a10+ 169810 +256a10+4096a10= 4369810. The slice levels required by the traditional thematic image layer processing training method are A10, A11, A12, A13, A14, A15 and A16, and the required slice space is A10+ A11+ A12+ A13+ A14+ A15+ A16= A10+4A10+ 16910 +64A10+256A10 1024A10+ 6A10=5461A10.

Therefore, the thematic layer can be easily compressed to 80% of the original size by performing layer processing based on the technical scheme. That is to say, this instrument can carry out the optional scale of choosing and carry out the section, needn't carry out the section according to continuous scale under the section scheme like traditional release mode, and stability is higher moreover, has practiced thrift the section time greatly when the layer lightweight.

When an image display instruction is detected, such as an image jump link corresponding to an image to be displayed, the image display instruction is analyzed to obtain display information, target tile data is determined from at least one type of tile data to be used based on the display information, a target display layer corresponding to the target tile data is determined, the target tile data is imported into the target display layer, and the target display layer is obtained and displayed. When the target tile data is imported into the target display layer, the data can be imported through an import tool in the GIS software, for example, the import tool can be a Bitvise SSH Client. As shown in fig. 5, according to the present embodiment, when the scale = 1.

According to the technical scheme of the embodiment, at least one piece of element information to be used related to the image to be displayed is obtained, the layer to be displayed is generated according to the element information to be used, and the element information to be used is processed according to layer generation software to obtain the layer to be displayed corresponding to the image to be displayed. Determining a to-be-used slicing scheme corresponding to the to-be-displayed layer according to the to-be-used scaling corresponding to the to-be-displayed layer, determining a corresponding level of to-be-displayed layer according to the to-be-used scaling, and determining a corresponding to-be-used slicing scheme, so as to slice the corresponding level of to-be-displayed layer based on each to-be-used slicing scheme. And carrying out slicing processing on the corresponding layers to be displayed based on each slicing scheme to be used to obtain at least one group of tile data to be used corresponding to each layer to be displayed. According to different scales to be used, the tile data to be used obtained by slicing the layer to be displayed by the slicing scheme to be used are different, and the tile data to be used corresponding to the layer to be displayed at the same level is used as a group of tile data to be used. When an image display instruction is received, determining target tile data from the at least one group of tile data to be used based on display information in the image display instruction, generating a target display image based on the target tile data, displaying, determining the target tile data from the at least one group of tile data to be used according to information such as display hierarchy, display area and display scale in the display information, determining a target display layer corresponding to the target tile data, importing the target tile data into the target display layer, obtaining a target display image, and displaying.
