人脸识别是生物特征鉴别技术的一个主要方向,与其他生物特征相比,人脸识别具有主动性、非侵犯性和用户友好等许多优点,多年来一直受到许多研究者的关注。但是目前的二维人脸识别技术由于受到光照、姿势、表情变化的影响,识别的准确度受到限制。由于人的脸部不是平坦的,所以3D人脸识别技术的算法具有较高的精确度,与其他的人脸技术相比具有明显的优势。 Face recognition is one of the main directions of biometrics. Compared with other biometrics, face recognition has many advantages, such as initiative, non-intrusiveness and user-friendliness, and has attracted many researchers’ attention for many years. However, the current two-dimensional face recognition technology is subject to light, posture, facial expression changes, the recognition accuracy is limited. As the human face is not flat, so 3D face recognition algorithm with high accuracy algorithm, compared with other face technology has obvious advantages.
