1. A three-dimensional model search method for retrieving a known three-dimensional model similar to a three-dimensional model as a search query which has been subjected to pose normalization, comprising the steps of: compensating a two-dimensional image for use in computation of a feature vector (excluding a contour feature vector) of said three-dimensional model as said search query so that gray scales of pixels are emphasized as the distance from a center of said two-dimensional image increases; performing a Fourier transform of said compensated two-dimensional image; computing a feature vector from the result of said Fourier transform; and comparing said obtained feature vector with a feature vector of said known three-dimensional model.
