摘要
结合距离相机获取人脸空间信息的精确性和数码相机获取人脸颜色信息的方便性,提出了一种彩色人脸的三维建模方法.首先,通过人脸的空间坐标信息和人脸颜色信息进行匹配,得到相应空间采样点的颜色信息;然后,进行采样点之间的插值,重建三维人脸的平滑表面.试验表明,这种方法是可行的,彩色人脸的三维模型的结果令人满意.
A method of the 3 D modeling of real-color face is proposed in conjunction of the accuracy of the three-dimensional field information of the face obtained by range camera and the convenience of obtaining the color information of the face with digital camera. First, this method finds the color information of the sampled points by matching the color information with the three-dimensional field information. Second, this method interpolates between the sampled points and reconstructs the smooth surface of the face. Experimental results show that this approach is feasible and the result of 3D modeling of the color face is satisfactory.
