[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution 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 part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0029] In the related art, users adopt Figure 1 Method 1 for taking high-quality images is that the user first learns professional knowledge such as light, camera and composition, then establishes the relationship between these professional knowledge and image effects, and finally forms his own shooting type and takes pictures. However, this method has the problem of cumbersome shooting.

[0030] Based on the above problems, the image capturing method provided by the present disclosure is to adopt Figure 1 The second method is to first shoot an image with the style and effect of the template image based on the template image, and the user can learn some professional knowledge during the shooting process.

[0031] refer to Figure 2 , is an example diagram of an application scenario provided by an embodiment of the present disclosure. Figure 2 As shown, the user needs to take a photo of a person in the scene shown in the preview image, but the user is not a professional photographer, so the user only needs to get the preview image to get Figure 2 The reference template image shown includes a person object, and the user can refer to the position and posture of the person object to efficiently capture high-quality images.

[0032] The above application scenario is only one of the scenario examples, and the embodiment of the present disclosure can be applied to image capture in any scenario.

[0033] refer to Figure 3 , is a flow chart of the image capturing method provided by the embodiment of the present disclosure. Figure 3 As shown, the image capturing method specifically includes the following steps:

[0034] S301: Acquire a preview image shot for a target scene.

[0035] In the present disclosure, a user can hold a terminal, turn on the camera and shoot a target scene to obtain a preview image. When shooting a preview image, the user can be prompted to shoot a field of view that includes objects that may appear in the final image as much as possible, which is convenient for subsequent analysis. After shooting and obtaining the preview image, the preview image can be uploaded to a server for analysis, or analyzed locally on the terminal.

[0036] S302: Determine at least one reference template image matching the preview image in a preset template library.

[0037] The reference template image includes a person object, a background object and a reference line. The similarity between the background object and the object in the preview image is greater than a similarity threshold. The reference line is used to identify the reference position of the person object in the preview image and the reference posture of the person object.

[0038] In the present disclosure, the preset template library includes a plurality of template images, and these template images have corresponding attributes, such as the amount of interaction, type or photographer, and the person objects, background objects and reference lines contained in the template images.

[0039] Furthermore, the background object in the reference template image is an object other than a person, and the similarity threshold is preset. In the present disclosure, the more the types of the background object and the object in the preview image are the same, the greater the similarity. Figure 2 , the objects in the preview image include: clouds and grass. The background objects in the reference template image include grass, clouds and windmills, which have the same objects of clouds and grass, so it can be determined that the similarity is greater than the similarity threshold. In the present disclosure, the similarity between the background object and the object in the preview image can also be determined by other methods, which are not limited here.

[0040] In addition, the reference line can identify the reference position and reference posture of the human object in the reference template image. Figure 2 The reference template image in FIG. 1 is a reference template image, wherein the dotted line in the reference template image is a reference line, which frames the person object and identifies the hand position, shoulder position and head position of the person object.

[0041] In the embodiment of the present disclosure, one or more reference template images may be determined. Each reference template image may contain part or all of the objects that appear in the preview image, such as Figure 2 The objects in the preview image are clouds and grass, and the reference template image also includes clouds and grass. The postures of the human objects in each reference template image are different.

[0042] Furthermore, the reference template image may also include object reference lines, which are used to identify the relative relationship between the person object and the background object and the relative relationship between the background objects, such as Figure 2 The mid-object guides are used to identify the relative relationship between the clouds and the grass.

[0043] S303: Display at least one reference template image.

[0044] Among them, when there are multiple reference template images, one of the reference template images can be displayed first, and when a user's switching operation (such as swiping up, down, left or right on the screen) is received, another reference template image is switched to display.

[0045] Further, the reference template image is used to guide the user to capture images with reference to the reference position and reference posture. It is understandable that when the user sees multiple reference template images, he can learn the reference position and reference posture of the human object in the reference template image, and then can imitate the reference template image to capture images.

[0046] In the present disclosure, the above steps may all be executed by the terminal, or S301 and S302 may be executed by the server, and S303 may be executed by the terminal.

[0047] This embodiment obtains a preview image shot for a target scene; determines at least one reference template image matching the preview image in a preset template library, the reference template image includes a human object, a background object, and a reference line, the similarity between the background object and the object in the preview image is greater than a similarity threshold, and the reference line is used to identify a reference position of the human object in the preview image and a reference posture of the human object; displays at least one reference template image, and the reference template image is used to guide a user to shoot an image with reference to a reference position and a reference posture. This application can achieve efficient shooting of high-quality images.

[0048] refer to Figure 4 , which is a flow chart of another image capturing method provided in an embodiment of the present disclosure.

[0049] like Figure 4 As shown, the image capturing method specifically includes the following steps:

[0050] S401, obtaining a preview image shot for a target scene.

[0051] The implementation process of this step refers to S301 and will not be repeated here.

[0052] S402: Obtain the target style selected by the user.

[0053] In the embodiment of the present disclosure, the order of S401 and S402 is not limited, and the order can be adjusted according to actual needs.

[0054] Among them, the user configures the target style and can perform the selected target style according to three steps. Figure 5 If the user selects the preset smart style as the mode, the subsequent type and photographer do not need to be selected. If the user selects the custom style as the mode, the user needs to select the type and photographer later, where the types include forest, scenery, portrait and check-in. If the user selects forest, scenery, etc., it is determined that the user wants to shoot natural landscape images, so a reference template image without human objects is provided to the user. The reference template image without human objects may include the same objects as the preview image, and the reference template image contains object reference lines between background objects for the user to refer to for shooting. If the user selects scenery, the reference template image can be obtained by further selecting the photographer to imitate and learn to shoot landscape images.

[0055] Furthermore, if the user selects the type as portrait and check-in, a reference template image containing a person object is recommended to the user. In addition, the user can also select the photographer, where Figure 5 A and B in the figure may represent specific photographers or types of photographers, and there is no limitation on this.

[0056] S403: Determine a plurality of template images matching the preview image in a preset template library.

[0057] The specific implementation process of this step refers to S302 and will not be repeated here.

[0058] Wherein, each template image has a corresponding style.

[0059] S404: Determine at least one reference template image that meets the target style among multiple template images.

[0060] In S403, a plurality of template images having high similarity to the object of the preview image are first determined, and then a template image that meets the target style is determined as a reference template image among the plurality of template images.

[0061] In the embodiment of the present disclosure, after the preview image is acquired, the preview image is first analyzed to obtain the object in the preview image, and then at least one reference template image is obtained in combination with the target style selected by the user. Furthermore, the person object in the reference template image can be extracted by image analysis, and then the reference line mark is performed on the person object in the reference template image. It can be seen that in the present disclosure, the reference line mark can be added in advance to the reference template image, or it can be added in real time, and the present disclosure does not limit this.

[0062] Among them, if the target style is a preset smart style, determining at least one reference template image that conforms to the target style includes: determining a template image whose interaction amount is greater than a preset threshold as at least one reference template image that conforms to the preset smart style, and the interaction amount includes: at least one of the likes amount, the collection amount and the forwarding amount.

[0063] In this disclosure, all user information is obtained with user authorization.

[0064] It can be understood that template images with a high number of likes, collections or reposts meet the preferences of most users, so these template images can be recommended to users as reference template images for reference.

[0065] In one embodiment, the target style includes: custom grids, the custom style includes: types and / or photographers, and the types include portraits or scenic spot check-ins.

[0066] In summary, users can select a custom style, and then select the type and / or photographer to obtain the reference template image they need. Figure 5 , the user selects a custom style, and then selects portrait and photographer A or A type. Then, among multiple template images, the template image whose style matches the portrait and the photographer is A or A type can be determined as a reference template image and recommended to the user.

[0067] S405, displaying a plurality of reference template images.

[0068] The specific implementation process of this step refers to S303 and will not be repeated here.

[0069] S406, responding to the user's triggering operation on the shooting control, switching to the shooting interface.

[0070] Among them, the current shooting picture and the target template image are displayed on the shooting interface, the target template image is displayed under the current shooting picture, the display transparency of the target template image is lower than the transparency threshold, and the target template image is one of the at least one reference template image.

[0071] Reference Figure 6, in the shooting interface, the brightness of the target template image is reduced, and the current shooting picture can be changed according to the movement of the camera. The current shooting picture is displayed on the target template image, and the target template image can assist the user in composing and shooting.

[0072] The person being photographed in the current shooting picture can accurately imitate the reference position and reference posture of the person object in the target template image, so that the user can shoot.

[0073] Further, refer to Figure 6 A shooting control is displayed on the shooting interface. The user touches the shooting control to take a photo of the current shooting screen.

[0074] In another embodiment, the current shooting picture may be displayed on the shooting interface, and the reference lines in the target template image may be displayed in the current shooting picture to assist shooting. In the target shooting image actually shot, there are no reference lines.

[0075] S407 , in response to a switching operation of the user on the shooting interface, switching the target template image to another reference template image among the multiple reference template images.

[0076] Among them, refer to Figure 6 A switch control is also displayed on the shooting interface, which can be used to slide or touch the switch control to switch the target template image. Other reference template images displayed on the shooting interface are also displayed under the current shooting screen with reduced brightness.

[0077] S408: Acquire the target image taken by the user.

[0078] Further, refer to Figure 6 A shooting control is displayed on the shooting interface. When the user touches the shooting control, the current shooting picture can be shot to obtain the target shooting image.

[0079] S409, determining a target position and a target posture of the photographed person in the target photographed image.

[0080] The target position is the image position of the photographed person in the target photographed image.

[0081] S410: If the target position and the reference position, and / or the target posture are different from the current posture, save the target captured image into a preset template library.

[0082] For example, refer to Figure 7 ,In the target shot image, the target position of the photographed person is different from the reference position of the reference person, and the target posture of the photographed person is different from the reference posture of the reference person.

[0083] Among them, saving the target captured image into the preset template library can enrich the preset module library.

[0084] Specifically, saving the target captured image to the preset template library includes: obtaining the shooting user identification of the target captured image; analyzing the shooting type of the target captured image; establishing a mapping relationship between the target captured image, the shooting user identification and the shooting type; and saving the mapping relationship to the preset template library.

[0085] The shooting type includes: a portrait type or a scenic spot check-in type. If the proportion of the human object in the image to the image is greater than or equal to a first preset value, the image is a portrait type. If the proportion of the human object in the image to the area of ​​the image is less than a first preset value, or there is a scenic spot in the image, and the proportion of the scenic spot to the area of ​​the image is greater than a second preset value, the image is a scenic spot check-in type.

[0086] Furthermore, a preset template library can be pre-built, and various types of images can be added as template images in the preset template library, such as scenic spot check-in images, idol imitation images, or creative collaboration images, etc. In addition, images taken by different professional photographers and images with high interaction volume on the Internet can be added as template images in the preset template library.

[0087] In the embodiment of the present disclosure, the user can select reference template images of different styles. After the user shoots a preview image, multiple reference template images can be determined based on the preview image and the target style selected by the user for the user to imitate and learn. In addition, during the user's shooting process, the determined target template image can be displayed on the shooting interface with reduced brightness for the user to imitate and learn more efficiently. Finally, the target shooting image shot by the user can also be used as a template image to enrich the preset template library. In summary, the present disclosure can achieve efficient shooting of high-quality images.
