Detailed Description
The embodiment of the invention discloses a photographing method and device, which are used for improving the quality of automatic photographing of a terminal. The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It is to be understood that the terminology used in the embodiments of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in the examples of the present invention and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.
Referring to fig. 1, fig. 1 is a schematic diagram of a photographing system according to an embodiment of the present invention. As shown in fig. 1, the system architecture diagram may include a terminal 101, a first server 102, and a second server 103.
The terminal 101 acquires a preview image, where the preview image may be acquired by a camera of the terminal 101, and the terminal 101 may be a smart phone, a tablet computer, a camera, or other devices including a camera, which is not limited herein.
The terminal 101 identifies the object to be photographed in the preview image, matches a corresponding composition (for example, an S-shaped composition, a spiral composition, a golden ratio composition, a squared figure, etc.) according to the shape presented by the position distribution of the object to be photographed in the preview image, and then the terminal 101 determines the target adjustment parameter that the object to be photographed needs to obtain according to the composition according to the position difference between the target position determined by the matched composition mode and the position distribution presented by the object to be photographed in the preview image. The target adjustment parameter can be used for indicating the terminal to adjust the position through the target adjustment parameter; and can also be used to instruct the subject to adjust by the target adjustment parameter. For example, the terminal 101 may adjust the position of the terminal 101 itself by manipulating the cradle of the terminal 101 by outputting the target adjustment parameter to the cradle of the terminal 101; the terminal 101 may output the target adjustment parameter to the object, and the object adjusts the position of the object according to the target adjustment parameter, for example, how the object performs position adjustment by voice broadcast through the terminal 101. The position, shooting angle, and the like of the subject in the preview image can be adjusted by the target adjustment parameter.
In some embodiments of the present application, after the terminal 101 identifies the photographed object in the preview image, a corresponding composition (for example, a diagonal composition, a trisection composition, and the like) may be determined according to the depth of the photographed object and the proportion of the pixel points of the photographed object in the pixel points of the preview image. The depth of the subject refers to a vertical distance between the subject and the camera. Referring to fig. 2, fig. 2 exemplarily shows a schematic diagram of a photographing imaging principle, and as shown in fig. 2, the terminal 101 may obtain the depth and the image distance of the photographed object, that is, the vertical distance between the imaging plane and the lens, by calculating. Then, the terminal 101 determines a target adjustment parameter according to a difference between the target position determined by the composition and the position of the subject in the preview image.
In some embodiments of the present application, after the terminal 101 identifies the photographed objects in the preview image, the number of the photographed objects may also be identified, and the composition (e.g., triangle composition, squared composition, etc.) corresponding to the preview image is determined according to the photographed objects. Then, the terminal 101 determines a target adjustment parameter according to a difference between the target position determined by the composition and the position of the subject in the preview image.
Optionally, after the terminal 101 acquires the preview image, the preview image may also be sent to the server 102, the server 102 identifies the photographed object in the preview image, determines a corresponding composition mode according to the photographed object in the preview image, then, the server 102 sends the target adjustment parameter to the terminal 101, and the terminal 101 outputs the target adjustment parameter.
After the terminal 101 detects that the shot object does not need to be adjusted in position, the terminal 101 can identify the age of the shot object and output the target audio and video from the audio and video library according to the age of the shot object. The fact that the subject does not need to be subjected to position adjustment means that the subject in the preview image has already been adjusted in position according to the selected composition or the terminal 101 detects a command that the position of the subject does not need to be adjusted. The target audio and video library may be from the second server 103, or may be pre-stored by the terminal 101. The target audio and video can be used for changing the expression of the shot object.
After the terminal 101 detects that the subject does not need to adjust the position, the terminal 101 may further output indication information indicating that the subject makes the posture described by the indication information. The indication information may be in the form of pictures, text, voice, video or other media.
The terminal 101 is also configured to detect, in real time, a feature state of the subject in the preview image, the feature state being a facial expression or gesture that can be recognized by the terminal 101. The characteristic state may be a designated state preset by the terminal 101, such as "smiley face", "V-shaped gesture", "blinking eye", and the like. When the terminal 101 detects that the characteristic state preset by the terminal 101 exists in the preview image, the preview image is saved. For example, "smiling face" is a feature state pre-stored in the terminal 101, the terminal 101 detects that a subject to be photographed shows a smiling face in a preview image, and the terminal 101 saves the preview image.
Alternatively, the first server 102 and the second service 103 may not be necessary.
Alternatively, the first server 102 and the second server 103 may be the same server.
Without being limited to the system architecture diagram shown in fig. 1, the photographing system provided in the embodiment of the present application may further include other devices, for example, a third-party server, which may be a server for detecting whether the preview image is suspected of illegal content. The first server 102 may provide third-party data and third-party functions for the photographing system through interaction with the third-party server, so as to further ensure services that the photographing system can provide.
Referring to fig. 3, fig. 3 is a schematic flow chart of a photographing method according to an embodiment of the present invention. As shown in fig. 3, the photographing method may be implemented by the photographing system shown in fig. 1, where the terminal may be the terminal 101, and the implementation of the photographing method may include the following steps.
S202, the terminal acquires a preview image.
The terminal can acquire the preview image in real time through the camera.
And S204, the terminal determines a target adjusting parameter according to the position of the shot object in the preview image, wherein the target adjusting parameter is used for indicating the adjustment of the position of the shot object in the preview image.
The terminal determines the target adjustment parameter according to the position of the shot object in the preview image, and may include that the terminal determines the target adjustment parameter according to a difference between the position of the shot object in the preview image and a target position in the target composition, the target position indicating the position of the shot object in the target composition. Then, the terminal outputs the target adjustment parameter. The terminal can output target adjustment parameters for indicating a bracket in communication connection with the terminal and can also output the target adjustment parameters for enabling the shot object to adjust the position.
And S206, when receiving the instruction information for instructing the adjustment completion, the terminal shoots.
And the terminal identifies the characteristic state in the overview image in real time, and when the characteristic state is identified, the terminal saves the preview image.
Two implementations of outputting the target adjustment parameter according to the position of the subject in the preview image in S204 are described below:
implementation mode (one):
as shown in fig. 4, fig. 4 is a flowchart for outputting the target adjustment parameter according to the position of the captured object in the preview image, and may include the following steps:
s301, the terminal determines target adjusting parameters according to the difference between the position of the shot object in the preview image and the target position in the target composition and the depth of the shot object, wherein the target adjusting parameters comprise the translation amount and the rotation amount of the terminal, and the target adjusting parameters are used for indicating the terminal to carry out position adjustment through the target adjusting parameters.
Referring to fig. 5, fig. 5 illustrates an exemplary method for determining an output target tuning parameter. As shown in fig. 5, G is the actual position of the subject, G1 is the position of G in the preview image, and G2 is the target position specified in the target composition corresponding to the preview image. As can be seen from fig. 5, G1 needs to be moved to the position G2, and according to the photographing imaging principle and the geometric operation relationship, the axial distance d1 between G1 and the imaging plane and the axial distance d2 between G2 and the imaging plane can be obtained, and the image distance M and the depth M of the object to be photographed can also be obtained. The terminal can obtain a path from G1 to G2 in the imaging plane, so that the actual path which the terminal needs to move is calculated according to the path in the imaging plane, the attribute parameters of the actual path are target adjustment parameters, and the attribute parameters comprise direction and distance. For example, as shown in fig. 5, according to the principle of reverse imaging, a path from G1 to G2 for "right translation D '" is determined, and the target adjustment parameter can be obtained as "right translation D'".
S302, the terminal sends the target adjusting parameter to a support so that the support can adjust the terminal according to the target adjusting parameter, and the support is in communication connection with the terminal.
Implementation mode (b):
as shown in fig. 6, fig. 6 is another flow chart for outputting the target adjustment parameter according to the position of the captured object in the preview image, and may include the following steps:
s401, determining a target adjusting parameter according to the difference between the position of the shot object in the preview image and the target position in the target composition and the depth of the shot object, wherein the target adjusting parameter is used for indicating the shot object to carry out position adjustment through the target adjusting parameter.
Referring to fig. 7, fig. 7 illustrates another method for determining target tuning parameters. As shown in fig. 7, a is the actual position of the subject, a1 is the position of a in the preview image, a2 is the target position in the target composition corresponding to the preview image, and a' is the adjusted actual position of a obtained from the target position of the target composition. As can be seen from fig. 7, according to the imaging principle and the geometric operation relationship, the distances d between the axial distances P1 and P2 of a1 and the imaging plane and between the axial distances P2 and a1 and a2 of the imaging plane can be obtained, and the image distance M and the depth M of the object to be photographed can also be obtained. The terminal can obtain a path from A1 to A2 on the imaging plane, thereby calculating the path of the shot object needing to move according to the path of the imaging plane, wherein the attribute parameters of the path are target adjustment parameters, and the attribute parameters comprise direction and distance. As shown in fig. 7, in order to keep the terminal unchanged, the terminal outputs the target adjustment parameter to the subject to adjust the position of the subject, so that the subject moves from the position a1 to a2 in the preview image, a path from a1 to a2 "shift right D" is determined on the imaging plane, and the actual path of a is "shift right D" according to the geometric operation relationship, so that the target adjustment parameter "shift right D" is obtained.
S402, the terminal outputs the target adjusting parameters.
The terminal outputs the target adjusting parameter to the shot object, and the terminal can output the target adjusting parameter in a voice form, can output the target adjusting parameter in a text form, and can output the target adjusting parameter in other forms.
Optionally, determining the position in the preview image to the target position in the target composition in the implementation manner (i) and the implementation manner (ii) may obtain different paths according to different algorithms, so that different target adjustment parameters may be obtained.
It should be understood that the principle of translation in other directions is the same as that of the left and right translation planes.
Before the terminal determines the target adjustment parameter according to the difference between the position of the shot object in the preview image and the target position in the target composition, the target composition of the preview image needs to be determined. The target composition may be a composition selected by the user in the composition gallery after the user opens the camera application of the terminal and before the shooting in step S206, or a composition selected by the terminal according to the acquired preview image.
Three implementation modes that the terminal selects composition according to the acquired preview image are introduced as follows:
implementation mode (one):
and the terminal determines the target composition as the composition corresponding to the shape presented by the position of the shot object in the preview image according to the corresponding relation between the shape and the composition.
Referring to fig. 8, fig. 8 is a flowchart of a method for determining a composition according to a shape presented by a position of a subject in a preview image, which may include the following steps.
S502, recognizing the shot object in the preview image.
Wherein the subject in the preview image can be identified by an image recognition algorithm. For example, a person in the preview image is recognized as a subject by a face recognition algorithm. Referring to fig. 9, fig. 9 is an exemplary illustration of a method of determining a composition according to a shape assumed by a position of a subject in a preview image. As shown in fig. 9, 5 persons in the image can be respectively identified by a face recognition algorithm: A. b, C, D and E.
And S504, determining a corresponding composition according to the shape presented by the position of the shot object in the preview image.
Determining the corresponding composition according to the shape assumed by the position of the photographed object in the preview image in S504 may include the following steps.
S5041, the position of the subject is specified.
As shown in fig. 9, after the terminal recognizes the subject, the position of the lips of the face of the person being photographed may be determined as the position of the subject. Other methods for determining the position of the object to be photographed may be used, for example, the position in the middle between the two eyes of the person to be photographed is used as the position of the person to be photographed, and the present invention is not limited thereto.
S5042, a shape showing the position of the subject is specified from the position of the subject.
After the position of each shot object is determined, the position of each shot object in the preview image is acquired, so that the shape presented by the position in the preview image can be determined. As shown in fig. 9, the location distribution where A, B, C, D and E can be obtained exhibits a substantially S-shape.
S5043, determining a corresponding composition according to the shape of the subject in the preview image.
The composition corresponding to the preview image can be matched in the corresponding relation between the shape and the composition pre-stored in the terminal according to the shape presented by the position of the shot object in the preview image. As shown in fig. 10, fig. 10 exemplarily shows a correspondence of a shape to a composition. For example, the determined position of the subject shown in fig. 9 may have an S-shape, and the most similar composition corresponding to the preview image may be matched to an S-shape composition in the correspondence relationship shown in fig. 10.
Implementation mode (b):
and the terminal determines the target composition as the composition corresponding to the depth of the shot object and the proportion of the pixel points of the shot object in the pixel points of the preview image according to the corresponding relation among the depth, the proportion and the composition.
Referring to fig. 11, fig. 11 is a flowchart of a method for determining a composition according to a depth of a photographed object and a ratio of pixel points of the photographed object to pixel points of a preview image according to an embodiment of the present application, where the method may include the following steps.
S602, recognizing the shot object in the preview image.
The same as step S502. For example, as shown in fig. 12, fig. 12 exemplarily shows a method of determining a composition according to a depth of a subject and a ratio of pixel points of the subject to pixel points of a preview image. As shown in fig. 12, the terminal can recognize the subject F.
And S604, acquiring the depth of the shot object.
The depth of the object is the vertical distance between the object and the lens.
And S606, acquiring the proportion of the pixel points of the shot object in the pixel points of the preview image.
After the terminal identifies the shot object, the number of the pixel points occupied by the shot object can be obtained, and therefore the proportion of the shot object in the pixel points of the preview image is calculated.
And S608, determining a corresponding composition according to the depth of the shot object and the proportion of the pixel points of the shot object in the pixel points of the preview image.
After acquiring the depth of the shot object and the proportion of the pixel points of the shot object in the pixel points of the preview image, the terminal searches the composition corresponding to the preview image in the corresponding relation among the pre-stored depth, proportion and composition. Referring to fig. 13, fig. 13 exemplarily shows a correspondence relationship between depth, scale, and composition. If the depth of the photographed object shown in fig. 12 is less than 30cm and the proportion of the pixel points of the photographed object in the pixel points of the preview image is greater than 45%, the composition of the preview image can be matched to a diagonal composition according to the corresponding relationship between the pre-stored depth, proportion and composition.
Alternatively, other compositions may be preset for the depth and scale according to the corresponding relationship of the depth, scale, and composition.
Implementation mode (c):
and the terminal determines the target composition as the composition corresponding to the number of the shot objects according to the corresponding relation between the number and the composition.
Referring to fig. 14, fig. 14 is a flowchart of a method for determining a composition according to the number of objects to be photographed, which may include the following steps.
S702, the shot object in the preview image is identified.
The same as step S502. Referring to fig. 15, fig. 15 illustrates a method of determining a composition according to the number of subjects to be photographed. As shown in fig. 15, the photographed objects A, B, C, D and E can be recognized in the preview image.
And S704, determining the number of the shot objects.
After recognizing the subject in the preview image, the terminal may acquire the number of subjects. For example, as shown in fig. 15, the number of subjects is 5.
And S706, determining a corresponding composition according to the number of the shot objects.
According to the number of the acquired shot objects, the composition corresponding to the preview image can be determined from the corresponding relationship between the pre-stored number and the composition. Referring to fig. 16, fig. 16 exemplarily shows a correspondence relationship between the amount and the composition. For example, it is recognized in fig. 15 that the number of subjects is 5, and the composition corresponding to the preview image may be determined to be a triangle composition from the correspondence between the number and the composition.
