基于双视角的真实感三维人脸重建系统

人脸建模是计算机图形学及三维重建领域的一个研究热点,论文根据结构光测量及编码原理,利用两组CCD及结构光投影仪实现了人脸双视角测量,保证了数据测量的范围和完整性;针对测量得到的几何及纹理数据,开发了可视化数据软件处理平台,能够完成两部分数据的精简、分割、拼接及网格化等处理过程,并通过纹理映射实现具有真实感的人脸模型三维重建;最终,将上述硬件测量方案及软件处理平台结合,形成了一套完整的三维人脸重建系统,并通过试验验证了系统的可行性。

A realistic 3D facial reconstruction system based on measurement from two viewpoints

Facial modeling is a hot research topic both in computer graphics and 3D reconstruction fields.This paper realizes facial measurement from two viewpoints with two groups of CCD and structural light projectors,ensuring the scope and the integrity of the measurement data.Pointing to the geometrical and texture data of measurement,this paper developes a visualized software platform for data processing,which can accomplish processes for two viewpoints including thinning,segmentation,jointing and meshing,and after texture mapping a realistic 3D facial model can be reconstructed.Finally,with the integration of the measurement system and the software process platform,an integrated system for 3D facial reconstruction is formed,and the flexibility of the system is proved by the experiment.
