Three-dimensional virtual make-up trial method and device

Abstract

The inventor provides a three-dimensional virtual make-up trial method in order to solve a virtual make-up trial problem. The method includes the following steps that an original person image, a standard model and a detail grid model of the standard model are obtained, the detail grid model of the standard model is built according to information of all characteristic points of the standard model, and the detail grid model of the standard model corresponds to the characteristic points one to one; the characteristic points of the standard model and the detail grid model of the standard model are subjected to aligning amendment processing according to information of characteristic points of the original person image, and a person image model and a detail grid model of the person image model are obtained; a rendering instruction is acquired, and rendering processing is performed on the person image model or the detail grid model of the person image model according to the rendering instruction. The invention further provides a corresponding three-dimensional virtual make-up trial device. The three-dimensional virtual make-up trial method and device are high in effect reality sense, information of a certain depth can be provided, and deformation of maps in the skinned animation process is avoided.

Description

technical field [0001] The invention relates to the field of computer image processing, in particular to a method and device for three-dimensional virtual makeup testing. Background technique [0002] Makeup is an indispensable part of women's daily life, so how to choose the cosmetics that suit them has gradually become a hot issue of concern to women. In recent years, with the development of computer simulation, the method of virtual makeup using image processing technology has begun to appear in people's field of vision. Time and resource consumption, has a wide range of application prospects. [0003] In the prior art, a non-contact analog virtual makeup test method detects the face image of the makeup tester according to the feature points of the face by analyzing the collected images, selects a suitable image containing the face as the makeup test image, and then According to the actual operation and based on the processing parameters of virtual makeup, image process...

AI Technical Summary

Problems solved by technology

[0005] 1. In the 3D model, UV maps are used to map the surface texture. Since the details in the model such as eyebrows, eye shadow, eyelashes, and cosmetic contact lenses account for a small proportion in the texture, a lot of detail information is often lost, resulting in detailed textures after mapping. less realistic

[0006] 2. Virtual makeup based on two-dimensional images is difficult to achieve the same simulation effect as three-dimensional makeup. Since the model has depth information in the three-dimensional scene, when the three-dimensional head model is rotated, the side after makeup should be able to be observed through the side Effects such as eyebrows, eyelashes, etc.

[0007] 3. In practical applications, the face model in the 3D scene usually needs to perform some facial animations, such as smiling, blinking, etc. The traditional texture mapping method will cause problems due to the stretching and shrinking of the picture when performing skin animation. Deformation of textures
