[0032] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data for display, data for analysis, etc.) involved in this disclosure are all information and data authorized by the user or fully authorized by all parties.
[0033] Example 1
[0034] According to an embodiment of the present invention, an embodiment of an image generating method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.
[0035] Figure 1 is a schematic diagram of an optional image generation method according to an embodiment of the present invention, such as Figure 1 As shown, the method comprises the following steps:
[0036] Step S101, obtaining a target area selected by a target object in a target map.
[0037] In step S101, the target area selected by the target object in the target map can be obtained through electronic devices, application systems, servers and other devices. In this embodiment, the target area selected by the target object in the target map can be obtained through a target application installed in the electronic device, and the target application can be an application related to land surveying. Among them, the target application can load the target map into the application interface through a relevant development framework for loading and rendering maps (such as: ArcGIS Runtime SDK for iOS) to allow the user to select the target area. Part of the icon area is as follows Figure 2 The shape of the target area is not limited according to different user requirements.
[0038] Step S102: determining a first target frame surrounding the target area.
[0039] In step S102, the target application may first obtain the frame size preset by the user, and determine the frame shape desired by the user based on the preset frame size, thereby determining the frame shape of the first target frame according to the preset frame shape. Optionally, the first target frame may be the minimum frame surrounding the target area under the preset frame shape, or may be enlarged according to preset requirements to generate a certain amount of blank space in the target area.
[0040] It should be noted that by determining the first target frame, a thumbnail of a desired shape can be obtained subsequently.
[0041] Step S103, determining a second target frame based on the target area and the first target frame, wherein the area enclosed by the second target frame is smaller than or equal to the display area of the target screen, and the target screen is used to display the target map.
[0042] In step S103, since the relevant user usually zooms in on the map when selecting the target area, Figure 2 As shown, the target area cannot be completely displayed in the display area of the target screen. Therefore, after the target application determines the first target border, it can synchronously reduce the target area and the first target border, that is, reduce it until the first target border can be completely displayed in the display area of the target screen, thereby obtaining the reduced first target border, that is, the second target border. Preferably, the second target border is equal in length or width to the display area of the target screen. Optionally, if the relevant user adjusts the display area to be too small after selecting the display area, the target application can also synchronously enlarge the target area and the first target border after determining the first target border, that is, enlarge it until the first target border is equal in length or width to the display area of the target screen.
[0043] It should be noted that by determining the second target frame based on the target area and the first target frame, the interception range corresponding to the target area is determined when the target area selected by the target object in the target map is fully displayed in the target screen.
[0044] Step S104, determining the screen coordinates corresponding to the vertices of the second target frame to obtain the first screen coordinates.
[0045] In step S104, the target application may directly determine the screen coordinates corresponding to all vertices of the second target border to obtain the first screen coordinates, or may first directly determine the coordinates corresponding to some vertices of the second target border, and then indirectly determine the coordinates corresponding to some vertices of the second target border according to a preset border shape, thereby obtaining the first screen coordinates. The screen coordinates are preferably logical coordinates.
[0046] It should be noted that the first screen coordinates are determined to determine the interception position for intercepting the display area in the target screen.
[0047] Step S105 , capturing the area surrounded by the second target frame based on the first screen coordinates to obtain a target thumbnail.
[0048] In step S105, the target application can directly capture the area surrounded by the second target border based on the first screen coordinates to obtain an initial thumbnail; the target application can also capture the complete display area of the target screen and then perform a second capture on the area surrounded by the second target border in the captured image based on the first screen coordinates to obtain an initial thumbnail.
[0049] Furthermore, the target application may also scale the initial thumbnail based on a border size preset by the user to obtain a target thumbnail that meets the user's expectations.
[0050] It should be noted that, by performing image capture based on the first screen coordinates to obtain a target thumbnail, an effect of automatically generating a fully viewable thumbnail according to any irregular polygonal area selected by the user on the map is achieved.
[0051] Based on the scheme defined in the above steps S101 to S105, it can be known that in an embodiment of the present invention, a method of generating a corresponding target thumbnail according to a border used to surround the map area selected by the target object is adopted, by obtaining the target area selected by the target object in the target map, and then determining a first target border surrounding the target area, and then determining a second target border based on the target area and the first target border, and determining the screen coordinates corresponding to the vertices of the second target border to obtain the first screen coordinates, thereby intercepting the area surrounded by the second target border based on the first screen coordinates to obtain a target thumbnail. Among them, the area surrounded by the second target border is less than or equal to the display area of the target screen, and the target screen is used to display the target map.
[0052] It is easy to notice that in the above process, by determining the first target frame surrounding the target area, and determining the second target frame based on the target area and the first target frame, the target area selected by the target object in the target map is fully displayed on the target screen. The interception range corresponding to the target area is determined, and by determining the screen coordinates corresponding to the vertices of the second target frame, the specific interception position corresponding to the target area is determined. Further, the area surrounded by the second target frame is intercepted based on the first screen coordinates to obtain a target thumbnail, thereby achieving the effect of automatically generating a fully viewable thumbnail based on any irregular polygonal area selected by the user on the map, thereby improving the efficiency of thumbnail generation.
[0053] It can be seen that the solution provided in the present application achieves the purpose of generating a corresponding target thumbnail based on the border of the map area selected to surround the target object, thereby achieving the technical effect of improving the efficiency of thumbnail generation, and further solving the technical problem of low thumbnail generation efficiency caused by the prior art relying on manual production of the selected map area into thumbnails.
[0054] In an optional embodiment, in the process of determining the first target frame surrounding the target area, the target application can determine the third target frame and determine the frame aspect ratio corresponding to the third target frame, so as to determine the aspect ratio of the target thumbnail based on the target size. If the frame aspect ratio is greater than the aspect ratio of the target thumbnail, the third target frame is extended in the first direction to obtain the first target frame. If the frame aspect ratio is less than the aspect ratio of the target thumbnail, the third target frame is extended in the second direction to obtain the first target frame. The third target frame is the minimum frame used to surround the target area, the frame aspect ratio is determined based on the screen coordinates corresponding to the third target frame, the target size is used to determine the size of the target thumbnail, and the first direction is different from the second direction.
[0055] Optionally, in this embodiment, the aforementioned development framework for loading and rendering maps can be ArcGIS Runtime API For iOS. The target application can call the relevant interface of ArcGIS Runtime API For iOS to determine Figure 3 The minimum frame surrounding the target area shown is also the third target frame.
[0056] Afterwards, the target application can determine the frame aspect ratio corresponding to the third target frame, and based on the frame size preset by the user, that is, the target size, determine the length (t_width) and width (t_height) of the target thumbnail, thereby determining the aspect ratio t_width / t_height of the target thumbnail to be generated.
[0057] Furthermore, the target application may compare the frame aspect ratio corresponding to the third target frame with the aspect ratio of the target thumbnail. When the frame aspect ratio corresponding to the third target frame is larger, the target application may extend the third target frame downward in the vertical direction by a certain distance so that the frame aspect ratio corresponding to the third target frame is equal to the aspect ratio of the target thumbnail, thereby obtaining the first target frame. Conversely, when the frame aspect ratio corresponding to the third target frame is smaller, the target application may extend the third target frame to the right in the horizontal direction by a certain distance so that the frame aspect ratio corresponding to the third target frame is equal to the aspect ratio of the target thumbnail, thereby obtaining the following. Figure 4 The first target frame shown. It should be noted that when the third target frame is extended in the vertical direction, the extension direction may also be upward, and when the third target frame is extended in the horizontal direction, the extension direction may also be leftward. Optionally, if the frame aspect ratio is equal to the target thumbnail aspect ratio, the third target frame may not be processed and may be directly used as the first target frame.
[0058] It should be noted that by first determining a minimum frame for surrounding the target area and then adjusting the minimum frame to obtain a first target frame having the same shape as the user's expected shape, the position of the first target frame can be determined efficiently and accurately.
[0059] In an optional embodiment, in the process of determining the border aspect ratio corresponding to the third target border, the target application can determine the screen coordinates corresponding to the vertices of the third target border, obtain the second screen coordinates, and then determine the border length and border width corresponding to the third target border based on the second screen coordinates, thereby determining the border aspect ratio based on the border length and border width.
[0060] Optionally, the target application can call the ArcGIS Runtime API For iOS related interfaces to determine Figure 3 The screen coordinates of the vertices of the third target border shown are used to obtain the second screen coordinates p1, p2, p3 and p4, so that the border length e_w and border width e_h of the third target border can be determined according to the second screen coordinates, and then the border aspect ratio e_w / e_h can be determined.
[0061] It should be noted that, by determining the frame aspect ratio based on the screen coordinates corresponding to the vertices of the third target frame, accurate determination of the frame aspect ratio is achieved.
[0062] In an optional embodiment, in the process of determining the second target border based on the target area and the first target border, the target application can determine the screen coordinates corresponding to the vertices of the first target border, obtain the third screen coordinates, and then determine the geographic coordinates corresponding to the third screen coordinates, thereby determining the second target border based on the geographic coordinates, the target area and the first target border.
[0063] Optionally, the target application can call the ArcGIS Runtime API For iOS related interfaces to determine Figure 4 The screen coordinates corresponding to the vertices of the first target frame shown are used to obtain the third screen coordinates p1, p2', p3, p4'. Afterwards, the target application can determine the geographic coordinates corresponding to the third screen coordinates based on the mapping relationship between the screen coordinates and the geographic coordinates.
[0064] Further, after determining the geographic coordinates corresponding to the third screen coordinates, the target application can call the relevant interface of ArcGIS Runtime API For iOS to reduce the target map based on the geographic coordinates corresponding to the third screen coordinates, so that the first target frame and the target area surrounded by it can be displayed in the display area of the target screen, thereby using the reduced first target frame as the Figure 5 The second target border is shown.
[0065] It should be noted that by adjusting the first target frame based on the geographic coordinates corresponding to the first target frame, it is ensured that the target area surrounded by the first target frame can be completely displayed in the display area of the target screen after adjustment.
[0066] In an optional embodiment, in the process of determining the screen coordinates corresponding to the vertices of the second target border to obtain the first screen coordinates, the target application can determine the geographic coordinates corresponding to the vertices of the second target border, and thus determine the screen coordinates corresponding to the vertices of the second target border based on the geographic coordinates corresponding to the vertices of the second target border to obtain the first screen coordinates.
[0067] Optionally, the target application can call the ArcGIS Runtime API For iOS related interfaces to determine Figure 5 The geographic coordinates corresponding to the vertices of the second target border shown are determined according to the mapping relationship between the new screen coordinates and the geographic coordinates, based on the geographic coordinates corresponding to the vertices of the second target border, to obtain the first screen coordinates p1', p3', p2" and p4".
[0068] It should be noted that, by determining the screen coordinates corresponding to the vertices of the second target border based on the geographic coordinates corresponding to the vertices of the second target border, the first screen coordinates are accurately determined.
[0069] In an optional embodiment, in the process of capturing the area enclosed by the second target border based on the first screen coordinates to obtain the target thumbnail, the target application can capture the display area of the target screen to obtain the first image, and then crop the first image based on the first screen coordinates to obtain the second image, thereby adjusting the second image based on the target size to obtain the target thumbnail.
[0070] Optionally, after determining the first screen coordinates, the target application may take a screenshot of the display area of the target screen to obtain a first image and store the first image. Afterwards, the target application may crop the first image based on the aforementioned first screen coordinates p1', p3', p2", and p4", to obtain a second image. Furthermore, since the shape of the second image is the same as the border shape preset by the user, but the size of the second image is not necessarily the same as the border size preset by the user (that is, the target size), the target application may scale the second image based on the target size to obtain a second image of the size expected by the user. Figure 6 Target thumbnail shown.
[0071] Optionally, when this embodiment is applied to a land surveying scenario, Figure 1 After the target area shown in FIG. 1 is processed according to the above method, the following can be obtained: Figure 7 The target thumbnail is shown. Figure 7 In , when the target application generates a target thumbnail, the target thumbnail can be displayed to the customer, and the corresponding application information can be displayed below the target thumbnail, such as Figure 7 The area information about the target area in the target thumbnail (such as Figure 7 area, perimeter), and related controls that can interact with the user, such as price calculation, plot information (such as Figure 7 Fill in the plot name, area, crop type), add photos, etc., and save controls.
[0072] It should be noted that by adjusting the second image in combination with the target size to obtain the target thumbnail, the thumbnail of the size desired by the user is effectively obtained.
[0073] It can be seen that the solution provided in the present application achieves the purpose of generating a corresponding target thumbnail based on the border of the map area selected to surround the target object, thereby achieving the technical effect of improving the efficiency of thumbnail generation, and further solving the technical problem of low thumbnail generation efficiency caused by the prior art relying on manual production of the selected map area into thumbnails.
