Abstract

An improved algorithm based on stereo matching technology is proposed to generate 3D face model. By improving and combining the region growing and dynamic programming methods together, a new algorithm of stereo matching is proposed. By processing region growing and dynamic programming methods on two nearly perpendicular directions separately, this new algorithm implements smooth restriction on multi-directions along with effective control of processing direction, which has improved the accuracy of matching notably. Besides, by choosing the outlines of face features as the baselines of region growing, the information of face characters also assists matching. This further improves the accuracy. Experimental results show that the reconstruction results are smooth and vivid.
一种基于立体匹配的三维人脸重建算法
提出了一种改进的基于立体匹配技术的三维人脸模型生成算法。通过对区域生长和动态规划方法的改进和结合,提出了一种新的立体匹配算法。该算法通过在两个几乎垂直的方向上分别采用加工区域生长和动态规划方法,实现了对多方向的平滑约束,同时对加工方向进行了有效的控制,显著提高了匹配精度。此外,通过选择人脸特征的轮廓作为区域生长的基线,人脸特征的信息也有助于匹配。这进一步提高了准确性。实验结果表明,重构结果平滑、逼真。
