The first embodiment,
An embodiment of the present invention provides a shooting method, and specifically, referring to fig. 2, the shooting method may include the following steps:
and S21, acquiring a preview image.
The preview image in the embodiment of the present invention is image data acquired before the main shooting is performed. The preview image is generally displayed on the terminal device to assist the user in checking whether the current shooting area is the area that the user wants to shoot, so as to adjust the shooting area.
In the embodiment of the present invention, the acquired preview image may be a two-Dimensional image acquired by acquiring an image through a conventional camera, or may also be a three-Dimensional image acquired by acquiring an image through a three-Dimensional (3D) depth camera.
And S22, constructing a three-dimensional model of the face of the target person in real time according to the preview image.
Specifically, when the preview image acquired in step S21 is a two-dimensional image, a three-dimensional model of the face of the target person can be obtained by calculating the face image of the target person acquired from different angles and a specific algorithm. For example, the algorithm for calculating the three-dimensional model of the face of the target person may be a convolutional neural network algorithm. When the preview image acquired in step S21 is a three-dimensional image, the three-dimensional model of the face of the target person can be acquired by only performing accurate measurement on the acquired three-dimensional image.

And displaying a two-dimensional special effect image generated according to the three-dimensional special effect image.
For example: the user selects the special effect of changing the nose of the target person into the pig nose through the first selection operation, then the nose of the target person is changed into the pig nose on the three-dimensional model of the face of the target person to generate a three-dimensional special effect image, and finally the two-dimensional special effect image generated according to the three-dimensional special effect image is displayed.
And S25, displaying the two-dimensional special effect image generated according to the three-dimensional special effect image.
According to the shooting method provided by the embodiment of the invention, the preview image is firstly obtained, the three-dimensional model of the face of the target person is built in real time according to the preview image, then the selection operation of the target special effect input by a user is received, the target special effect is added on the three-dimensional model of the face of the target person in response to the selection operation of the target special effect to generate the three-dimensional special effect image, and the two-dimensional special effect image generated according to the three-dimensional special effect image is displayed.
In some cases, a user may take a picture of multiple characters at the same time and add a special effect to one or more of the characters, however, in the prior art, when adding a special effect, the user who wants to add a special effect cannot be selected, and thus, only the special effect can be added to all the users or the special effect added by all the users can be cancelled. In view of the above problem, referring to fig. 3, the photographing method according to an embodiment of the present invention further includes, before the step S22 (building the three-dimensional model of the face of the target person in real time from the preview image),:

S33, determining the at least one person as the target person in response to the second operation.
In the embodiment of the present invention, there may be one or a plurality of target persons, some persons in the preview image, or all persons in the preview image.
In the above embodiment, the user may input a selection operation on at least one person in the displayed preview image, so as to determine the selected at least one person as a person to which the special effect is to be added.
Further optionally, after the step S33 (determining the at least one person as the target person), the shooting method according to the embodiment of the present invention further includes:
