摘要:
本文针对重建三维人脸模型对人脸图像姿态要求较高,提出基于单张人脸图像姿态预估计的模型重建算法。首先介绍单张人像的三维姿态估计方法,然后通过建立的人脸形状模型样本库,利用主成分分析(PCA)进行三维人脸稀疏模型的重构,最后利用径向基函数变换得到对应的密集三维人脸形状向量。试验结果表明,算法可重构精确的三维人脸形状模型,对有旋转姿态的人脸图像有很好的重建效果。

Abstract: Aiming at facial pose request in reconstructing 3D face model, a new method to reconstruct 3D face shape model from a single face image is proposed. First, the method of face pose estimation is described in detail. Then, the spare 3D face shape model is reconstructed by principal component analysis (PCA). Finally, the final 3D face shape model is obtained using radius base function. Expe-rimental results show that the proposed method can obtain precise reconstruction model and is more efficient with face image under rotated pose.
