Problems solved by technology

Moreover, the existing 3D modeling method takes as long as several minutes, and such waiting is unacceptable for interactive applications, because users who are accustomed to real-time interaction on the Internet cannot wait that long
However, the accuracy of the existing 3D modeling method based on a single photo is too poor. Only the outline of the facial features is relatively accurate in the obtained face model, and the rest of the position lacks details, so it has no practical value at all.

Embodiment Construction

[0030] The purpose and effects of the present invention will become more apparent by describing the present invention in detail below in conjunction with the accompanying drawings.

[0031] Such as figure 1 As shown, the present invention is based on the fast face three-dimensional model generation method of single image, comprises the following steps:

[0032] Step 1: Input frontal face images.

[0033] Step 2: Extraction of facial features of the input image

[0034] Facial features of the input image were extracted using the method described in Xudong Cao, Yichen Wei, Fang Wen and Jian Sun, "Face Alignment by Explicit Shape Regression," International Journal of Computer Vision paper. The facial features include points on the contour line of the face, and points on the contour lines of the eyes, nose, and lips.

[0035] Step 3: Fine-tuning of input image facial features

[0036] Because the input image is usually not an absolute frontal photo, there is asymmetry in the p...

Abstract

The invention discloses a rapid face three-dimensional model generation and transformation method based on a single image. According to the method, a three-dimensional face model can be generated in real time by using a single frontal face image so that the three-dimensional model can be used for application of real-time human-computer interaction, such as multi-angle face identification, 3D printing and face changing. Real-time transformation between the face and other faces can also be realized on the basis. The rapid face three-dimensional model generation and transformation method based on the single image is simple in operation, high in generation speed and sufficient in precision.

Description

technical field [0001] The invention relates to a method for generating and transforming a three-dimensional model of a human face, in particular to a method for generating a three-dimensional human face model in real time based on a human face image, and a method for transforming between the human face model and other three-dimensional models to be processed. Background technique [0002] Three-dimensional modeling has a wide range of applications and extremely high practical value. It is a fundamental technology in the booming computer fields such as virtual reality and 3D printing. It also plays an effective enhancement role in image recognition at the same time. For example, the recognition and association of multi-angle photos of the same object. With the 3D model, it is possible to compare photos of the same person from different angles, so as to identify whether the same person appears in different photos. [0003] Existing common methods of modeling based on 3D ph...
