EAR SHAPE ANALYSIS METHOD, EAR SHAPE ANALYSIS DEVICE, AND METHOD FOR GENERATING EAR SHAPE MODEL

摘要

A computer generates ear shape data by applying a principal component weight vector to an ear shape model indicating a relation between ear shape data sets and principal component weight vectors, each ear shape data set representing a difference between a point group representing a three-dimensional shape of an ear and a point group representing a three-dimensional shape of a reference ear, and each principal component weight vector indicating weights of principal components of the corresponding ear shape data set. From the ear shape data generated, the computer identifies an estimated three-dimensional shape of a target ear corresponding to a target ear image represented by image data.
