Research On 3D Face-reconstruction Technology

With wide application in films, computer games, plastic surgery and so on, more andmore attention is paid to face reconstruction field. Now, there are two kind methods togenerate realistic face-model, one is to generate face model by facial measurement, andthe other is reconstructing facial model according to photos or video. Base on the factualconditions, this paper gives two face generation projects. We can generate face-model bystructure light measure system if we can measure the special face. Otherwise, we cangenerate realistic face model by modifying the general face-model base on the front andprofile facial photos. The content and main work of this paper as follows.1,The method of generating face-model is that modeling by processing scanningfacial data which obtained from structure light measure system. In this paper, we studythe process of face generation and the application in art and sculpture, bring forward themethod of hair substitution to solve the hair modeling problem that is difficult toscanning method, and put forward the method of eyes substitution, that can make facemodel realistic in the condition of eyes closed scanning.2,The method of generating realistic face-model base on photos makes thenormalized front and profile face photos as input, and defines the facial feature points onthe research of human facial feature, and obtains the feature points information, thenmodifies the general face-model according to the information, at last, does the texturemapping. This paper proposes a method of defining the feature point template to simplifythe feature points obtained operation, constructs the texture map with multi-resolutiontechnique, and completes the texture mapping through cylindrical projection. Till now,the system design and the interface design of the face generation software have beenfinished.
