人脸皱纹三维测量与量化系统

Three-Dimensional Facial Wrinkle Measurement and Quantification

人脸皱纹的三维测量与量化在众多领域有着重要的应用价值。该文提出了一套完整的系统,实现了对人脸皱纹的三维测量与量化。首先,该系统采用基于结构光的立体视觉测量方法,完成了系统标定、对应点匹配与三维反求,实现了人脸皱纹的三维测量。其次,该系统将皱纹视为叠加在人脸光滑轮廓上的噪声,采用三维噪声提取与形态学处理方法,实现了人脸皱纹的量化。实验结果表明,该文提出的系统可以实现对人脸皱纹的准确测量与客观量化评价,且具有非接触、高精度等特点,具有广泛的应用前景。

The three-dimensional facial wrinkle measurement and quantification have important applications in many fields,which are implemented by an entire system proposed in this paper.The system uses stereo vision method based on structured-light to achieve three-dimensional facial wrinkle measuring,where the system calibration,corresponding points matching and three-dimensional reverse method are implemented.Furthermore,the facial wrinkle is considered as the noise attached on smooth facial profile so that the facial wrinkle is acquired quantitatively by three-dimensional noise acquisition and morphologic processing method.The experimental results show that this system can accomplish accurate facial wrinkle acquisition and objective quantification.This system has comprehensive applications as it is non-contact and it has high precision.
