[0025] The wallpaper generation method provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0026] Please see Figure 1 , which is a flowchart of a wallpaper generation method provided in an embodiment of the present application. The method can be applied to an electronic device, which can be a mobile phone, a tablet computer, a laptop computer, etc. Figure 1 As shown, the method may include steps S1100 to S1300, which are described in detail below.

[0027] Step S1100, obtaining the outline information of the target building.

[0028] The target building is determined by positioning the electronic device or by images acquired by the electronic device.

[0029] In one example, a target building can be located by an electronic device.

[0030] In this example, the electronic device is provided with a positioning device. The positioning device may be a wireless transceiver with a GPS positioning module. The GPS positioning module mainly communicates with satellites, obtains the latitude and longitude information of the electronic device in real time, and uses the obtained latitude and longitude information as the position information of the electronic device to locate the electronic device. For example, the building located by the GPS positioning module of the electronic device may be Figure 2 The building in the left image can also be Figure 3 The building in the middle left image.

[0031] In one example, the target building can be determined through an image acquired by an electronic device.

[0032] In this example, a camera is provided on the electronic device, and the user captures an image of a landmark building in the target area using the camera of the electronic device, and the electronic device determines that the landmark building is the target building based on the image.

[0033] The target area can be a country, a city, an administrative area of ​​a city, etc.

[0034] The landmark buildings in the target area may include buildings with cultural symbolic significance. The landmark buildings in the target area may also include buildings ranked high by the user's preference. The landmark buildings in the target area may also include buildings with a height exceeding a set height and / or a floor area exceeding a set area.

[0035] like Figure 2 As shown in the image on the left, the user can capture an image of a landmark building (grand theater) in city A using the camera of the electronic device, and the electronic device determines that the landmark building is the target building based on the image.

[0036] like Figure 3 As shown, the user can capture an image of a landmark building (square) in city A based on the camera of the electronic device, and the electronic device determines that the landmark building is the target building based on the image.

[0037] The contour information of the target building can reflect the overall appearance of the target building.

[0038] In this embodiment, after the target building is determined, contour information of the target building may be extracted based on edge detection.

[0039] by Figure 2 Take the left image of the example, the target building is a theater. Figure 2 The left image is edge detected to obtain the outline information of the theater. Figure 2 As can be seen from the middle image, the overall appearance of the city's grand theater is simple and powerful, resembling a glass space-time ship.

[0040] After obtaining the outline information of the target building, enter:

[0041] Step S1200 , performing three-dimensional reconstruction on the target building according to the contour information of the target building, and generating a target image including the three-dimensionally reconstructed target building.

[0042] In this embodiment, after obtaining the contour information of the target building, the target building can be three-dimensionally reconstructed according to the contour information of the target building, thereby generating a target image including the three-dimensionally reconstructed target building. That is, according to this step S1200, it is equivalent to performing a secondary creation on the target building according to the contour information of the target building, so that the created target image can reflect the core features of the target building.

[0043] In this embodiment, the target building can be divided into different types according to the type of the building. Since the shapes of different types of target buildings are quite different, after obtaining the contour information of the target building, it is necessary to combine the type of the target building to perform three-dimensional reconstruction of the target building, and then obtain a target image containing the three-dimensionally reconstructed target building.

[0044] Here, in this embodiment, in step S1200, the target building is three-dimensionally reconstructed according to the contour information of the target building, and obtaining the target image including the three-dimensionally reconstructed target building may further include the following steps S1210 to S1220:

[0045] Step S1210: reconstruct the target building in three dimensions according to the outline information of the target building and the type of the target building, and obtain a second image including the three-dimensionally reconstructed target building.

[0046] The types of target buildings include, for example but not limited to: single building type, building group type, mountain building group type, bridge and road.

[0047] A building of the monolithic type is a building that is composed of multiple building structures on the same horizontal line, which are partially overlapped and intertwined to form a building. A building of the monolithic type can be called a monolithic building.

[0048] Buildings of the building complex type are composed of multiple single buildings on the same horizontal line. Alternatively, buildings of the building complex type are composed of single buildings on the same horizontal line and adjacent single buildings connected together in the form of contact points. Buildings of the building complex type can be called building complexes.

[0049] The buildings of the mountain building complex type are buildings built according to natural landforms and topography. The buildings of the mountain building complex type are buildings on different horizontal lines, which are closely integrated with the environment.

[0050] The above bridges are structures built to allow roads to cross natural or artificial obstacles.

[0051] The above roads are buildings for various trackless vehicles and pedestrians to pass through.

[0052] In one example, the above three-dimensional reconstruction of the target building according to the outline information of the target building and the type of the target building to obtain the second image containing the three-dimensionally reconstructed target building may further include the following steps S1211a to S1212a:

[0053] Step S1211a, when the type is a single building type, three-dimensionally reconstruct the target building based on the outline information, target visual data and target proportion parameters.

[0054] The target proportion parameter is a parameter of the screen proportion of the target building in the target image. In the case where the type is a building type, the target proportion parameter may be 70%, that is, the screen proportion of the target building in the target image must exceed 70%.

[0055] The target visual data is the angle data with the most spatial levels of the target building.

[0056] continue Figure 2 For example, the target building is a theater, and the theater is a single building type building. Figure 2 It can be seen from the left image and the middle image that the outline of the theater is similar to that of a glass spaceship. In addition, since the front of the theater has the most three-dimensional spatial layers, the target visual data is the front view angle data. Here, the outline information, front view angle data and target proportion parameters can be processed based on the three-dimensional reconstruction software to obtain a three-dimensional model of the theater. The three-dimensional reconstruction software is not limited.

[0057] Step S1212a, blurring the background outside the target building to obtain a second image including the three-dimensionally reconstructed target building.

[0058] In this step S1212a, in addition to performing three-dimensional reconstruction on the target building, it is also necessary to perform blurring processing on the background other than the target building to obtain a second image including the three-dimensionally reconstructed target building.

[0059] The blurring of the area except the target building includes: extracting the background outside the target building, and performing different blurring processes on the background according to different background types.

[0060] For example, when the background includes multiple roads, the multiple roads may be filtered to retain only one main road, and the main road may be three-dimensionally reconstructed according to the above step S1211a.

[0061] For another example, when the background is a bridge, and the bridge occupies more than 30% of the image captured by the electronic device, the bridge is three-dimensionally reconstructed according to the above step S1211a.

[0062] For another example, when the background includes a lake or a river, and the lake or the river occupies more than 30% of the image captured by the electronic device, the lake or the river is three-dimensionally reconstructed according to the above step S1211a.

[0063] For another example, when the background includes vegetation, and the vegetation occupies more than 30% of the image captured by the electronic device, the vegetation is three-dimensionally reconstructed according to the above step S1211a.

[0064] In one example, the above three-dimensional reconstruction of the target building according to the outline information of the target building and the type of the target building to obtain the second image containing the three-dimensionally reconstructed target building may further include the following steps S1211b to S1213b:

[0065] Step S1211b, when the type is a building complex type, determine the main area of ​​the target building according to the outline information and the target visual data.

[0066] The main area of ​​the target building is the area that can reflect the core features of the target building.

[0067] The target visual data is the angle data with the most levels of target building controls.

[0068] by Figure 3 Take the left image of as an example, the target building is a square, and the square is a building of the building group type. Figure 3 As can be seen from the left image, the square is composed of eight towers with curved facades and a crystal corridor, which connects four of the towers. In addition, since the square has the most three-dimensional spatial layers on its front side, the target visual data is the front view angle data.

[0069] from Figure 3 From the left image, we can see that the most recognizable parts of the square are the two super-tall towers and the crystal corridor in the middle, so the two super-tall towers and the crystal corridor in the middle are determined as the main area of ​​the square. Here, the main area of ​​the square can be extracted by taking the central axis area of ​​the outline information of the square at a normal viewing angle as symmetry.

[0070] Step S1212b: Acquire contour information of the main body area as first contour information.

[0071] by Figure 3 Taking the middle image of as an example, the main area of ​​the square extracted is the two super-high towers and the crystal corridor in the middle. Since the main area presents an H shape, the H-shape contour information can be extracted as the first contour information.

[0072] Step S1213b, based on the first contour information and the target proportion parameter, three-dimensionally reconstruct the target building, and blur the background outside the target building to obtain a second image including the three-dimensionally reconstructed target building.

[0073] The target proportion parameter is a parameter of the screen proportion of the target building in the target image. In the case where the type is a building complex type, the target proportion parameter may be 50%, that is, the screen proportion of the target building in the target image must exceed 50%.

[0074] In this step S1213b, after extracting the H-shaped contour information as the first contour information, the first contour information and the target proportion parameter can be processed based on the above-mentioned 3D reconstruction software to obtain the 3D model of the square. The background outside the square is blurred to obtain a second image containing the 3D reconstructed square. For how to blur the background, refer to the example of the above step S1212b, which will not be described in detail here.

[0075] In one example, the above three-dimensional reconstruction of the target building according to the outline information of the target building and the type of the target building to obtain the second image containing the three-dimensionally reconstructed target building may further include the following steps S1211c to S1214c:

[0076] Step S1211c: when the type is a mountain building complex type, the target building includes a plurality of single buildings located at different heights.

[0077] In this step S1211c, when the type of the target building is a mountain building complex, since the multiple individual buildings in the mountain building complex are located at different horizontal lines, the multiple individual buildings have different heights.

[0078] Step S1212c, obtaining the height relationship between multiple individual buildings.

[0079] In this step S1212c, in order to perform three-dimensional reconstruction of the target building of the mountain building type, it is necessary to distinguish the height relationship between multiple individual buildings in the target building. By obtaining the height relationship between the multiple individual buildings, the spatial hierarchy of the target building can be obtained.

[0080] Step S1213c: determining the second outline information according to the height relationship between the multiple single buildings.

[0081] In this step S1213c, after obtaining the height relationship between multiple individual buildings to obtain the spatial hierarchy of the target building, since the target building of the mountain building complex type has more spatial hierarchies, the spatial hierarchy can be filtered according to the height relationship between the multiple individual buildings, and the contour information of the target building with obvious spatial hierarchy is retained as the second contour information.

[0082] Step S1214c: perform three-dimensional reconstruction on the target building according to the second contour information and the target proportion parameter, and blur the background outside the target building to obtain a second image including the three-dimensionally reconstructed target building.

[0083] The target proportion parameter is a parameter of the screen proportion of the target building in the target image. In the case of a mountain building complex type, the target proportion parameter may be 40%, that is, the screen proportion of the target building in the target image must exceed 40%.

[0084] In this step S1214c, the second contour information and the target proportion parameter can be processed based on the above-mentioned 3D reconstruction software to obtain a 3D model of the target building. The background other than the target building is blurred to obtain a second image containing the 3D reconstructed target building. For how to blur the background, refer to the example of the above step S1212b, which will not be described in detail here.

[0085] Step S1220: performing preset processing on the second image to obtain a target image including the three-dimensionally reconstructed target building.

[0086] The preset processing includes effect processing and / or material processing. The effect processing includes, for example, frosted semi-transparent, lighting effects, etc. The material processing includes, for example, metal, wood texture, etc.

[0087] Continuing with the example in step S1212a above, the theater effect is set to frosted in the second image, and a rectangular hollow window array is added to the three-dimensional model of the theater to obtain Figure 2 The right image of is used as the target image.

[0088] Continuing with the example of step S1213b above, two super-high tower steel frame structures and translucent facade materials are set in the second image, and the four towers on both sides are set to metal materials, and the obtained Figure 3 The right image of is used as the target image.

[0089] After the target building is 3D reconstructed according to its outline information and a target image including the 3D reconstructed target building is generated, the following steps are performed:

[0090] Step S1300, setting the target image as wallpaper.

[0091] In this embodiment, setting the target image as wallpaper in step S1300 may further include: receiving an input for setting the target image as wallpaper, and in response to the input, setting the target image as desktop wallpaper and displaying it.

[0092] According to this embodiment, the target building is first determined by positioning the electronic device or the image obtained by the electronic device, and the target building is reconstructed in three dimensions according to the contour information of the target building, thereby generating a target image including the target building after three-dimensional reconstruction and setting the target image as wallpaper. That is, the wallpaper in this application is a target image obtained by three-dimensionally reconstructing the target building based on the contour information of the target building, and the wallpaper can not only show the style of the target building, but also retain the overall characteristics of the target building.
