Three-dimensional data generating apparatus, three-dimensional data generating method, and three-dimensional data generating program

A three-dimensional data generating apparatus comprises: a model creating unit (1) that uses three-dimensional face data of a plurality of persons as learning data to generates a plurality of three-dimensional shapes of a face of a person projected onto a projection space by varying the viewpoint thereto, obtains the three-dimensional coordinates of each of a plurality of points on the three-dimensional shapes, conducts a principal component analysis for the three-dimensional coordinates and drawing brightness of the face to obtain the average vector and base vector, and creates a model of the face of the person wherein the three-dimensional coordinates and drawing brightness is expressed as a linear sum of the average vector and base vector, and model parameters; a fitting learning unit (2) that conducts fitting by deforming the model so as to match the face of the person within an input image, and generates three-dimensional data of the face of the person within the input image; and a fitting execution unit (3).
