摘　　要：针对传统三维形变模型计算量大,难以满足实时性的不足,提出一种实用、高效的三维形变模型,进行个性化三维人脸重建。首先,对三维人脸关键特征点定位,分割划片;然后,对每个分片分别建立形变模型并进行匹配恢复其局部形状信息;最后,把每部分进行无缝拼接,生成逼真的三维人脸。实验结果表明,该方法能够获得较好的建模精度,在短时间内可以通过单幅真实图像重建出逼真的三维人脸模型。Traditional 3D morphable models have large quantity of calculation, thus it can＂ t meet the demand of real-time performance. To solve this problem, a practical and efficient three-dimensional morphable mode/ is proposed to reconstruct a personalized 3D face. Firstly, feature extraction and segmentation on 3D faces are given. Then, morphable model for each block and optimize matching is built to obtain the shape information. At last, personalized 3D face reconstruction is completed by integrating each block seamlessly. Experimental results show that this method has the advantages of short modeling time and low complexity, and the 3D faces generated from real-world photos are rather realistic based on a few landmarks.
