Human face 3D model's facial part adjusting method and device thereof

Abstract

The invention provides a human face 3D model's facial part adjusting method and a device thereof, wherein method comprises the following steps: obtaining a human face 3D model of a user based on the structured light; extracting a first 3D feature of at least one feature point from the human face 3D model; matching the first 3D feature with a second 3D feature of the feature point in a pre-stored reference human face 3D model; when the matching degree of the first 3D feature and the second 3D feature exceeds a threshold value, replacing the first 3D feature with the second 3D feature in the human face 3D model; and forming a target human face 3D model of the user. According to the invention, the method is based on the structured light to obtain a human face 3D model so that the 3D image can be beautified. As the human face 3D model can carry the depth information of various feature points, it is possible to replace the feature points in the human face according to the depth information so that the beautification effect becomes more prominent. Besides, the replacement of the feature points in the reference human face 3D model and the feature points in the human face 3D model becomes more natural, therefore, increasing the user's use experience.

Description

technical field [0001] The present invention relates to the field of terminal equipment, in particular to a face adjustment method and device for a 3D model of a human face. Background technique [0002] With the popularization of terminal devices, more and more users like to use the terminal devices to take pictures. And in order to make the image more attractive, various applications for beautifying the image have been developed. [0003] When taking a selfie, users can choose their favorite materials from all the materials that come with the application to process the image according to their own needs. Eyes to replace your own eyes in the image to make selfie images more charming. However, at present, the beautification of images by all applications is performed on two-dimensional images, so that the materials cannot be perfectly fitted or matched with the images, resulting in poor image processing effects. Contents of the invention [0004] The present invention ai...

Problems solved by technology

[0005] For this reason, the first object of the present invention is to propose a face adjustment method for a 3D model of a human face, so as to realize the beautification of the three-dimensional image, so that the beautified part fits the actual scene more closely, so that the image processing effect is better, and Solve the problem that the existing image beautification or enhanced special effects are all carried out on two-dimensional images, so that the material cannot be perfectly fitted or matched with the image, resulting in poor image processing effect
