Wherein each combined tooth model comprises a plurality of single tooth models adjacent to each other in position and facial features applicable to the single tooth models. Therefore, according to the embodiment of the invention, the corresponding combined tooth model can be matched according to the facial features, so that the teeth are adapted to the face, and the overall attractive effect is further improved. In addition, in the embodiment of the invention, a plurality of adjacent single teeth are replaced as a whole, so that more processing methods for the tooth images are provided for users, and the requirements of different users are further met.
Optionally, the determining, from the pre-stored combined tooth models, a target combined tooth model matched with the feature information of the face image includes:

Wherein the first input may be a touch operation by the user on a touch screen of the terminal displaying the combined tooth model for a certain displayed combined tooth model.
From the above, the embodiment of the present invention can match corresponding combined tooth models according to the facial features, and the user can also select one of the matched combined tooth models that is satisfactory to himself as the target combined tooth model, thereby replacing the teeth in the tooth region on the facial image with the target combined tooth model. The user can select the satisfied user from the combined tooth model matched according to the face characteristics according to the actual requirements of the user, and the actual requirements of the user are further met, so that the use experience of the user is improved.
In addition, adaptive 3D fusion techniques may be employed specifically when replacing teeth in a tooth region on a face image with a target composite tooth model.
Optionally, the image processing method further includes:
detecting a protruding portion in the tooth region;
in the event that a protruding portion is present in the tooth region, the protruding portion is cleared.

detecting whether a target grid exists in triangulation grids of the triangulation network, wherein the difference between the height of the target grid and the height of a grid adjacent to the target grid is out of a preset range;
the tooth portion formed by the target mesh is determined as a protruding portion.
The tooth region can be processed by adopting a triangulation algorithm, so that whether target grids which are obviously higher than adjacent grids exist in each formed triangulation grid or not is judged.

Wherein the ratio of the length of a single tooth to the width of the gum is outside of a preset range, indicating that the ratio of the length of the tooth to the area of the gum is unsuitable. In the embodiment of the invention, when the ratio of the tooth length to the gum area is not suitable, the ratio of the adjusted tooth length to the gum width can be within a preset range by adjusting the length and/or the gum width of a single tooth, so that the ratio of the tooth length to the gum area reaches the ratio of aesthetic requirements, and the whole tooth is more attractive.
Preferably, a plurality of individual tooth models are stored in advance; the image processing method further includes:
determining a target tooth position in the tooth region to be adjusted;
determining a target single tooth model matched with the target tooth position from a plurality of single tooth models stored in advance;
replacing teeth at the target tooth position in the tooth region with the target single tooth model.
Therefore, the embodiment of the invention can also replace a single tooth by using a single tooth model, and provides more processing methods for the tooth images for users, thereby further meeting the requirements of different users.
Further, the determining a target single tooth model matched with the target tooth position from a plurality of single tooth models stored in advance comprises:
determining at least one single tooth model matched with the target tooth position from a plurality of single tooth models stored in advance according to the target tooth position, and displaying the single tooth model;
receiving a second input;
and responding to the second input, determining a single tooth model aimed by the second input from the displayed single tooth models, and taking the single tooth model as a target single tooth model.
The second input may be a touch operation of the user on the touch screen of the terminal displaying the single tooth model for a certain displayed single tooth model.
As can be seen from the foregoing, the embodiments of the present invention can select a single tooth to be replaced according to the actual operation of the user, and automatically recommend the matched single tooth model according to the position of the single tooth to be replaced, so that the user can select one of the automatically recommended single tooth models that is satisfied with himself as the target single tooth model, thereby replacing the teeth in the tooth area with the target single tooth model. The user can select the user's satisfaction from the automatically recommended single tooth model according to the actual demand of the user, and the actual demand of the user is further met, so that the use experience of the user is improved.
In addition, when the single tooth model to be adjusted is replaced by the target single tooth model, the adaptive 3D fusion technology can be adopted.
Preferably, the image processing method further includes:
receiving a third input;
in response to the third input, the position and/or size of teeth in the tooth region is adjusted.
Wherein the third input may be a sliding operation of the user on the touch screen of the terminal displaying the tooth region with respect to the tooth region.
That is, in the embodiment of the invention, the tooth position and/or the size of the tooth area on the face image can be adjusted according to the actual operation of the user, so that the operation requirement of the user is further met. For example, a user may fine tune the teeth by finger opening and closing dragging on a touch screen of a terminal displaying the tooth area.
From the above, it can be seen that the embodiments of the present invention can detect the protruding portion in the tooth area (i.e., detect whether or not there is a tooth, and remove it, can adjust the ratio of the tooth length to the gum width, can replace several adjacent individual teeth with the combined tooth model, can replace individual teeth with the individual tooth model, and can adjust the position and/or size of the teeth according to the actual operation of the user.
