    Research on Key Technology in Construction of a Chinese 3D Face Database

    • 摘要: 通过CyberWare人脸专用扫描仪获取高分辨率的彩色三维人脸来构建中国人三维人脸数据库. 创建三维人脸数据库时,要对原始三维人脸数据进行预处理,并通过规格化将三维人脸表示 为统一的标准形式.规格化的关键是要建立三维人脸数据基于特征的稠密对应,这是图形学 和计算机视觉中的难点问题,目前使用光流方法建立的对应效果并不理想,因此提出了基于 网格重采样的计算方法,取得了良好的对应效果.

       

      Abstract: By acquiring the human faces through the CyberWare 3D scanner, a Chinese 3D colo r face database is constructed. To build 3D face database, the original 3D data should be preprocessed, and the 3D faces should be standardized in a uniform for mat. The key to the problem of standardization is the pixel-to-pixel alignments among the 3D faces, which is a difficult problem in computer graphics and comput er vision. Generally, the optical flow algorithm is used for the alignments, but the result is not so good. To get precise alignments of the 3D faces, a method based on resample algorithm is proposed. The experimental result shows the metho d is feasible.
