To provide a technique for easily generating a quality three-dimensional avatar based on a two-dimensional facial image.SOLUTION: A three-dimensional avatar generation device includes: a facial image input unit 1 for inputting a facial image of a target object, which is a two-dimensional image; a head shape generation unit 4 that generates three-dimensional shape information on the head of the target object based on the facial image of the target object and a head body avatar; a surface image generation unit 5 that generates information about a surface image of a head shape surface based on the facial image of the target object; a head avatar generation unit 7 that generates a head avatar based on the three-dimensional shape information on the head and the surface image information; and an avatar combining unit 11 that combines the head avatar, a body avatar, and a hair avatar and generates an integrated full-body avatar.SELECTED DRAWING: Figure 1 【課題】２次元の顔面画像に基づき高品質な３次元アバターを容易に生成する技術を実現する。【解決手段】２次元画像である対象物の顔面画像を入力するための顔面画像入力部１と、対象物の顔面画像及び頭部素体アバターに基づき対象物の頭部の３次元形状情報を生成する頭部形状生成部４と、対象物の顔面画像に基づき頭部形状表面における表面画像に関する情報を生成する表面画像生成部５と、頭部の３次元形状情報及び表面画像情報に基づき頭部アバターを生成する頭部アバター生成部７と、頭部アバターと胴体アバター及び頭髪アバターを合成して一体の全身アバターを生成するアバター合成部１１とを備える。【選択図】図１
