A face recognition system based on three-dimensional data, for providing a complete three-dimensional face recognition solution, involving: data feature region extraction, data registration, data pre-processing, data quality evaluation, feature extraction and data classification. The quality of three-dimensional data is preliminarily evaluated on a point cloud layer, and a nasal tip region is detected; the nasal tip region is taken as reference data for registration; depth face image mapping is carried out; after the image quality is evaluated again, texture restoration is performed on depth face data; and finally, according to a trained three-dimensional face visual dictionary, visual dictionary histogram vector extraction is performed on the three-dimensional data, and three-dimensional face identification is realized by using a classifier. The quality of face data and the efficiency of three-dimensional face recognition are improved.
