Patent ID: 7620217

Claim:
A three-dimensional (3-D) face recognition system, comprising: a first data storing module for storing a plurality of 3-D face model data and two-dimensional (2-D) face image data; an input unit for inputting 3-D face model data and 2-D face image data; a signal converting module for converting analog data of the 3-D face model data and 2-D face image data inputted by the input unit to digital data; a second data storing module for storing the digital data of the 3-D face model data and 2-D face image data after converted by the signal converting module; a microprocessing module for analyzing geometric characteristics of various points in the 3-D face model data stored in the first data storing module and the second data storing module so as to determine feature points of the 3-D face model data and store the feature points in the respective first and second data storing module, wherein the 2-D facial image data is used to assist in confirming the various feature points of the 3-D face model data in order to select the most outstanding feature points in each region, and different weight ratios being given to different feature points; a comparing module for comparing the feature points stored in the first data storing module and the second data storing module analyzed by the microprocessing module, during which, different geometric characteristics being given different weight ratios, and calculating relativity between the two sets of feature points to obtain a comparison result; and an output unit for outputting the comparison result compared by the comparing module.
