基于三维模型的人脸姿态估计

摘要

Thefaceposeestimationmethodbasedon3Dmodelisproposed.First,thespareface model is built according to the feature points of the face.Then,based on the 3D face model,linear regression is used to estimate the face pose preliminarily and the 3 D face pose is revised to acquire the accurate pose value.Finally,the face pose is estimated accurately.The experiment results show that the estimation method can obtain satisfying result and achieve better accuracy.%提出了一种基于三维模型的人脸姿态估计方法。首先根据人脸特征点重建出稀疏的三维人脸模型，然后基于三维模型采用线性回归的方法对人脸姿态进行初步估计，确定姿态范围，再对估计结果进行修正，从而对人脸姿态进行精确估计。实验表明，该方法具有较好的估计效果，提高了姿态估计精度。
