Abstract: A series of 2D images of human head is obtained from magnetic resonance imaging technology. Their boundary coordinates are extracted respectively, and a hierarchical 3D head parameterized model is constructed by fitting contours of all sections with Fourier series. Whereafter, certain feature sections are defined according to main features of human face. Average processing is also taken to several samples based on the principle of facial feature matching. Accordingly, the materialized 3D standard head-face model is constructed, featuring the comprehensive characteristics of specific population. As examples, round-high standard headform is calculated and constructed through 558 samples, as the design basis for head-face equipment.
