Embodiment Construction

[0049] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0050] see figure 1 , the present invention specifically comprises the following steps:

[0051] (1) Establish a standard face library and general face background texture

[0052] This solution first needs to establish a standard face library. In theory, the more the number of different standard faces in the face library, the closer the final generated face model is to the actual face. This program temporarily uses seven standard face models, including long face, oval face, square face, pear face, diamond-shaped face, heart-shaped face, and round face, which basically cover several common face shapes of oriental beauties. For each model in the face library, the feature points of the face must be calibrated, because the vertices of the models in ...

Abstract

The invention discloses a single photograph-based fast face modeling method. The method includes the following steps that: the three-dimensional model base of various standard faces is established; facial feature point recognition is performed on an inputted face photograph through a face recognition technology; the face photograph is zoomed, translated and rotated on the basis of facial feature points, so that the face of the photograph is preliminary overlapped with face grids under a uv plane; a feature face is completely overlapped with a uv face; a facial feature region is extracted, and Poisson fusion is performed on the facial feature region and an original texture map, so that a new map can be formed; whitening and dermabrasion are performed on the new map; a weight is solved according to face contour parameters and face contour feature points, a new three-dimensional face model is constructed; and texture mapping is performed on the new face map and the new three-dimensional face model, so that a complete three-dimensional face model can be obtained. With the method of the invention adopted, by means of a single photograph, a three-dimensional face model close to the photograph can be generated fast.

Description

technical field [0001] The invention relates to a fast face modeling method based on a single photo, belonging to the technical field of face reconstruction. Background technique [0002] Since Parke established the first 3D face model in the 1970s, 3D face reconstruction has become a research focus in the field of computer graphics, and has achieved certain breakthroughs and progress. The application fields of 3D face reconstruction are very wide, and can be used in film and television animation, medical graphics, face recognition, virtual test hair, virtual fitting, etc. [0003] Traditional face modeling is often done manually by artists, which consumes a lot of time and manpower, and makes it difficult to popularize 3D head reconstruction technology. Existing fast face modeling methods have low stability, slow modeling speed, and poor user experience. And if there is a means to realize the reconstruction of the 3D head model through a single frontal face photo, this wi...
