Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present 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.
Referring to fig. 1, a flowchart of a shooting prompting method in the embodiment of the present invention is shown, which may specifically include the following steps:
In the embodiment of the present invention, the terminal device may generally be installed with photographing software having a composition prompting function, and before the user needs to use the composition prompting function, the user may first enter the three-dimensional model corresponding to the target object in the terminal device, so that the displayed three-dimensional model may be used as a photographing reference for the target object in the composition prompting process of photographing. The target object may be a person, that is, any user, and certainly, in practical applications, the target object may also be an object, such as a sculpture and the like, which is not specifically limited in this embodiment of the present invention.
Fig. 2 shows a flowchart of another shooting prompting method in the embodiment of the present invention, and referring to fig. 2, a specific implementation manner of this step may include:
substep 1011: three-dimensional information of at least one shooting posture of the target object is acquired.
Substep 1012: and establishing a three-dimensional model of the target object according to the three-dimensional information of the at least one shooting posture.
In the embodiment of the invention, for any target object, the terminal device can acquire the three-dimensional information of at least one shooting gesture of the target object, and further can establish the exclusive three-dimensional model of the target object according to the three-dimensional information of at least one shooting gesture, so that the exclusive three-dimensional model of the target object can be adopted to perform composition prompt in the subsequent process of shooting the target object, and thus, the intuitiveness of composition prompt on the target object is stronger, and particularly, the scene substitution sense of the target object during shooting can be improved under the condition that the target object is a person.
The terminal device can receive a three-dimensional modeling instruction, and in response to the three-dimensional modeling instruction, the terminal device can acquire three-dimensional information of at least one shooting gesture of the target object. Specifically, when a user needs to enter a three-dimensional model corresponding to a target object in the terminal device, the user can click the photographing software icon, so that the terminal device can open the photographing software, and further can enter a photographing preview interface. Then, the user can switch to the front-end photographing mode, and further can click the virtual button of the three-dimensional modeling, and correspondingly, the terminal equipment can receive the three-dimensional modeling instruction.
The terminal equipment can be configured with a depth camera, and after receiving the three-dimensional modeling instruction, the terminal equipment can respond to the three-dimensional modeling instruction, so that the depth camera is started to acquire three-dimensional information of at least one shooting posture of the target object, namely the three-dimensional information of the target object at different angles.
Taking the target object as an example of the user, the three-dimensional information may include front face depth information, left side face depth information, right side face depth information, parietal depth information, and chin depth information of the target object. In practical application, the photographing software can prompt the user to photograph from five directions, namely the front face direction, the left side face direction, the right side face direction, the head top direction and the chin direction, through the interface as shown in fig. 3, so that the depth camera can acquire the front face depth information, the left side face depth information, the right side face depth information, the head top depth information and the chin depth information of the user. In addition, referring to fig. 3, the terminal device may further display an information acquisition progress bar in the three-dimensional information acquisition interface, so that the acquisition progress of the depth information may be displayed in the process of inputting the depth information by the user. For example, as shown in fig. 3, the user may sequentially enter depth information in five directions according to the direction of an arrow, the user may first enter front face depth information, and when the front face depth information is entered, the terminal device may display that the current acquisition progress is 25% in the three-dimensional information acquisition interface, and may display prompt information that the front face entry is completed.
Similarly, when the target object is an object, the user can adjust the placing position of the object relative to the terminal equipment and shoot through the depth camera, so that the terminal equipment can acquire the depth information of the object in different shooting postures.
The photographing software can be configured with a three-dimensional modeling algorithm, and when the terminal device acquires the three-dimensional information of at least one photographing gesture of the target object, the three-dimensional information of the at least one photographing gesture can be input into the three-dimensional modeling algorithm, so that the three-dimensional modeling algorithm can establish and output a three-dimensional model of the target object. And the terminal equipment can store the three-dimensional model of the target object as a local file of the photographing software locally. It should be noted that, the three-dimensional modeling algorithm in the embodiment of the present invention may refer to related technologies, and details of the embodiment of the present invention are not described herein.
In practical applications, a user may establish a three-dimensional model belonging to a target object through photographing software, so that the terminal device may store the three-dimensional model of at least one target object. Taking a target object as an example, when a certain user needs to take a picture, a composition prompting function of the shooting software can be started before the picture is taken, after the terminal device recognizes a face in a shooting preview interface, the user can press a face area in the shooting preview interface for a long time, so that the terminal device is triggered to match the front face of the user in the shooting preview interface with a front image corresponding to any three-dimensional model stored in the terminal device, and when the front face of the user is matched with the front image corresponding to any three-dimensional model stored in the terminal device, the three-dimensional model of the user can be determined to exist in the terminal device. When the matching is unsuccessful, the terminal equipment can pop up a prompt box to prompt that the three-dimensional model corresponding to the user is not stored currently.
It should be noted that, in the embodiment of the present invention, a related face matching technology may be referred to in a manner of matching the front face of the user with the front face image, if a similarity between the front face of the user and the front face image of any one of the three-dimensional models is greater than or equal to a preset similarity, it may be determined that the front face of the user matches the front face image of the three-dimensional model, and if the similarity between the front face of the user and the front face image of the three-dimensional model is less than the preset similarity, it may be determined that the front face of the user does not match the front face image of the three-dimensional model, which is not described herein again in the embodiment of the present invention.
In the embodiment of the invention, the terminal device can identify the scene information of the preview image, so that how the three-dimensional model of the target object is displayed can be determined according to the scene information of the preview image. In one implementation, the scene information may specifically include a background environment of the preview image, that is, under what environment scene the target object is photographed, for example, an environment scene including plant flowers, an environment scene including buildings, an environment scene including animals, an environment scene including people in pictures or human sculptures, and the like, including non-living human faces, and the like, so as to facilitate a subsequent determination of what composition template should be used according to a type of the environment scene.
In practical applications, the environment scene type may be identified through a scene identification technology, for example, an environment scene identification algorithm based on deep learning, an environment scene identification algorithm based on object identification, and the like, which is not specifically limited in the embodiment of the present invention. For example, for an actual background environment such as a person oil painting, a person sketch, a person sculpture, and the like, the terminal device may recognize that the scene information of the current preview image includes a non-living human face.
Of course, since the environment scene recognition technology usually has a certain recognition error rate, in a specific application, when a user has a recognition error in a background environment, the user may select a correct environment scene type in the terminal device according to an actual situation, which is not specifically limited in the embodiment of the present invention.
In another implementation, the scene information may specifically include the first display position and the first display information of the target object, that is, a specific implementation of this step may include: a first display position and first display information of a target object are acquired.
The first display position is also the display position of the target object currently in the preview image, and the first display information is also the display parameters of the target object currently in the preview image except the first display position, such as the attitude orientation of the target object, the inclination relative to any central axis, and the like. In practical applications, a user may want to take some more interesting photos, for example, two faces that are the same as the user are displayed, and the positions of the two faces are mirror-symmetric interesting photos, so that the terminal device can obtain a first display position and first display information of a target object, and further can determine a display position that has a certain positional relationship with the first display position and display information that has a certain corresponding relationship with the first display information. In addition, when acquiring the first display position and the first display information of the target object, the terminal device may perform a shooting operation to output a first image when the target object is at the first display position and has the first display information, so as to subsequently obtain an interesting photo based on the first image.
And 103, determining model display parameters corresponding to the scene information.
In an embodiment of the present invention, the model display parameters may include model basic display parameters and model detail display parameters, wherein the model basic display parameters may include at least one of the following: the model size, the model display direction, the model display angle, the model display position, namely, some parameters necessary for composition prompting. When composition prompting is carried out, the model size can indicate the optimal size of the three-dimensional model of the target object in the shooting preview interface, the model display direction can indicate the optimal orientation of the three-dimensional model of the target object in the shooting preview interface, such as the front of the three-dimensional model faces to the left, the front of the three-dimensional model faces to the right and the like, the model display angle can indicate the transverse and longitudinal central axis of the three-dimensional model of the target object in the shooting preview interface and the angle formed between the transverse and longitudinal central axis of the shooting preview interface, and the model display position can indicate the optimal shooting position of the three-dimensional model of the target object in the shooting preview interface, such as the middle position in the shooting preview interface, the lower right position in the shooting preview interface and the like, so that guidance of shooting composition of the target object can be carried out. In addition, the model detail display parameters may include a display style of at least one part of the model, such as a hair style, a facial expression, and the like of the three-dimensional model, that is, some parameters that can be used to perform composition prompting in a more detailed manner.
The basic display parameters of the model and the detail display parameters of the model are used for displaying the three-dimensional model, so that a user can visually check the basic characteristics and detail characteristics of the three-dimensional model, the user can conveniently control the target object to simulate the posture of the three-dimensional model, and the scene substituting feeling of the user when shooting the target object can be improved.
In an implementation manner of this step, for different types of environment scenes, the terminal device may determine, through a related composition algorithm, a composition template corresponding to the type of the environment scene, and may further determine a model display parameter in the composition template. The composition template may be configured to display composition elements in the current background environment, for example, an optimal position, an optimal size, an optimal angle, and the like of the three-dimensional model of the target object in the current background environment, and composition elements such as a geometric composition dividing line, which is not specifically limited in this embodiment of the present invention.
In another implementation manner of this step, the terminal device may perform more interesting composition guidance for the user, and specifically, this step may include: and determining a second display position and second display information according to the first display position and the first display information. The second display position is a mirror image position or a preset non-mirror image position of the first display position. Specifically, the mirror image position is a display position that is symmetrical to the first display position with respect to a longitudinal central axis of the preview image in a mirror symmetry manner, and the preset non-mirror image position may be, for example, a display position that is displaced from the first display position by a preset distance along a preset direction, a display position that is symmetrical to the first display position with respect to a center point of the preview image, and the like. The second display information is also the display parameters of the three-dimensional model of the target object except the second display position.
The second display position which is in mirror image equal relation with the first display position is determined, so that the subsequent terminal equipment can display the three-dimensional model of the target object at the second display position, and when the target object is shot according to the three-dimensional model at the second display position, the terminal equipment can output images containing two target object images with mirror image equal position relation, so that the shooting interest can be improved, and more interesting pictures can be obtained.
In addition, in practical applications, a user may manually select whether to perform interesting composition guidance, for example, referring to fig. 4, the user 01 and the three-dimensional model 02 of the user 01 are displayed in a preview image, the user may manually slide the right side of the preview image from top to bottom to trigger the terminal device to display the interesting composition guide frame 03 as shown in fig. 5, and the user may further select any one of interesting composition guide modes such as mirror image and non-mirror image in the interesting composition guide frame, for example, the user may select the "mirror image" interesting composition guide mode, so that the terminal device may subsequently display the three-dimensional model at a second display position which is mirror-symmetrical with respect to the first display position of the user in the shooting preview interface, wherein the orientation of the three-dimensional model is opposite to the face of the user due to the mirror-symmetry.
And 104, displaying the three-dimensional model in a shooting preview interface according to the model display parameters.
In the embodiment of the present invention, after determining the model display parameter corresponding to the scene information, the terminal device may display the three-dimensional model of the target object in the shooting preview interface according to the model display parameter, so as to perform composition prompting on the user, for example, the user may adjust the shooting posture according to the three-dimensional model of the user, or may place the object according to the three-dimensional model of the object, so as to adjust the shooting posture of the object, and so on. In order to facilitate the user to perform posture adjustment on the target object according to the composition prompt, in practical application, the terminal device may perform semi-transparent display on the three-dimensional model.
In addition, in a specific application, the terminal device may also display the three-dimensional model according to the basic model display parameters, and then the user selects whether to perform further detail guidance according to the detailed model display parameters.
Furthermore, in the embodiment of the invention, the user can also press the interesting composition guide frame and slide upwards for more than 1 second, so that the terminal device can be triggered to enter the customized composition function, at the moment, the user can adjust the size of the three-dimensional model through double-finger zooming, drag the three-dimensional model to any position in the shooting preview interface, rotate the three-dimensional model to adjust the direction and the angle, and thus adjust the model display parameters of the three-dimensional model in the current shooting preview interface. After the overall effect is confirmed, the user can press the three-dimensional model for a long time, and then the terminal device is triggered to enter a detail self-defining mode, at the moment, the terminal device can record detail parameters such as the expression and the hair style of the target object in the shooting preview interface, and details such as the expression and the hair style are displayed on the three-dimensional model according to the detail parameters. After the detail effect is confirmed, the user can use the customized composition content as the composition template corresponding to the scene information, and further can perform composition prompt through the model display parameters in the customized composition template during subsequent photographing.
Of course, in practical applications, the terminal device may also directly display the three-dimensional model when acquiring the three-dimensional model of the target object, and then adjust the position, the size, and the like of the three-dimensional model according to the model display parameters corresponding to the scene information, which is not specifically limited in the embodiment of the present invention.
Referring to fig. 2, after step 104 is completed, the terminal device may further perform the following steps 105 and 106, which specifically include:
and 105, detecting the attitude parameters of the target object in the shooting preview interface.
After displaying the three-dimensional model of the target object to perform composition prompting, the terminal device may detect the attitude parameter of the target object in the current shooting preview interface. The parameter attribute of the attitude parameter is the same as the parameter attribute of the model display parameter, that is, the attitude parameter also includes an attitude basic parameter, or further includes an attitude detail parameter. The basic gesture parameters may include the size, the position, and the like of the target object, and the detail gesture parameters may include a display style of at least one portion of the target object, that is, parameters of which attributes are specifically included in the model display parameters, and the parameters of which attributes of the target object in the current shooting preview interface are detected, so as to obtain the gesture parameters of the target object.
And 106, executing shooting operation and outputting a target image under the condition that the posture parameters are matched with the model display parameters.
After detecting the current attitude parameter of the target object, the terminal device may perform similarity matching on the attitude parameter and the model display parameter, and when the similarity between the attitude parameter and the model display parameter is smaller than a preset similarity, the terminal device may determine that the attitude parameter is not matched with the model display parameter, and may further wait for the target object to adjust the attitude so as to detect the attitude parameter again after a preset duration, or may also prompt the user in the interface that the target object is not currently aligned with the three-dimensional model so as to detect the attitude parameter again after the user adjusts the attitude of the target object until the attitude parameter is matched with the model display parameter.
When the similarity between the posture parameter and the model display parameter is greater than or equal to the preset similarity, the terminal device can determine that the posture parameter is matched with the model display parameter, and then the terminal device can automatically execute shooting operation through the camera, so that the shooting operation after composition guidance can be realized under the condition that a user does not conveniently operate the terminal device, and a target image can be output.
In specific implementation, when a user wants to obtain an interesting photo containing two faces which are the same and are mirror-symmetric in position, the terminal device can transfer a target object which is located at a first display position in a first image and has first display information to the first display position in the target image after the target image is obtained by shooting, so that the target image can contain two images of the target object which are mirror-symmetric in left and right.
In addition, in practical application, after the target object is adjusted to the posture matched with the three-dimensional model, the terminal device may further highlight the three-dimensional model, so as to prompt that the posture of the target object is adjusted in place, the highlight may disappear after 5 seconds, and the user may manually shoot by himself or herself, which is not specifically limited in the embodiment of the present invention.
It should be noted that, because the time interval between the shooting and the recording of the target object into the three-dimensional model may be relatively large, details such as a hairstyle may have a relatively large difference, and further, a simulation degree may be relatively low, so in practical applications, for the model detail display parameters, the preset similarity required when the model detail display parameters are matched with the posture parameters may be set to be smaller, for example, 40%, 35%, and the like, that is, when the posture parameters of the target object are matched with the model detail display parameters to a relatively small degree, it may be considered that the target object has simulated details such as a hairstyle, and a hairstyle to a certain extent, which is not specifically limited in the embodiment of the present invention.
In addition, in practical application, the terminal device may take a picture through a common camera configured besides the depth camera, but before taking a picture, conversion of the camera needs to be performed, or the terminal device may also take a picture directly through the depth camera which establishes the three-dimensional model, so that conversion of the camera does not need to be performed before taking a picture, which is not specifically limited in the embodiment of the present invention.
In the embodiment of the invention, the terminal equipment can firstly acquire the three-dimensional model corresponding to the target object in the preview image displayed on the shooting preview interface, then can identify the scene information of the preview image, further determine the model display parameters corresponding to the scene information, and display the three-dimensional model in the shooting preview interface according to the model display parameters, thereby realizing composition prompt. In the embodiment of the invention, the three-dimensional model corresponding to the target object has the three-dimensional detail characteristics of the target object, such as the details of five sense organs, expression, hairstyle of a person, and sharp corners and gaps of an object, and further the terminal equipment can display the three-dimensional model of the target object in the shooting preview interface according to the model display parameters corresponding to the current scene information so as to perform composition prompt, so that a user can more intuitively find the three-dimensional details of the target object in the current scene, and thus, the intuitiveness of the composition prompt is stronger, and the scene substitution sense of the user during shooting is improved.
