摘要: 人脸是人类重要的生物特征,逼真重建三维人脸面部表情有着广泛的应用,多年来一直受到研究人员的密切关注。目前,比较成熟的人脸三维模型获取大多还是依靠实验室昂贵的硬件系统和可控的光照环境,而学术界的研究热点已逐渐过渡到基于日常生活环境和低成本设备的研究。按照输入数据的来源,将现有的研究工作分为两大类:一是基于可控环境的三维人脸获取及重建技术;二是基于非可控环境的三维人脸获取及重建技术。以此为线索对当前技术和方法进行总结分类,并在此基础上探讨了当前研究存在的问题和未来的研究方向。

Abstract: Face is an important biological feature of human. High-fidelity 3D face construction is widely applied and has attracted the attention of researchers for a long time. Now the mature 3D model acquisition still depends on the expensive hardware and controlled lighting environment in the lab. However, academic focus has gradually transformed to researches based on daily living environment and low cost equipment. According to the source of input data, the existing works are divided into two categories: works under controlled environment and uncontrolled environment. Methods are summarized and classified based on the categories. Existing problems and future research directions are discussed in the end.

Key words: 3D face acquisition, 3D face modeling, controlled environment, uncontrolled environment, coarse face model, fine-detailed face model, feature detection
