Claim 0:
1. A human face data processing method, comprising:
acquiring a picture of a human face by means of a scanning apparatus, obtaining point cloud information by means of a structured light stripe, and further obtaining a three-dimensional model of the human face; and
mapping the three-dimensional model onto a circular plane in an area-preserving manner so as to form a two-dimensional human face image,
wherein the mapping of the three-dimensional model comprises:
determining a boundary of a two-dimensional plane;
harmonically mapping the three-dimensional data to an interior of the boundary to form harmonic mapping points;
calculating second weights of the harmonic mapping points, and further calculating a weighted Voronoi diagram of the harmonic mapping points; and
mapping the three-dimensional model onto the two-dimensional plane in the area-preserving manner according to the weighted Voronoi diagram.
