More Information
Summary:Provided is a face pose correction apparatus for correcting a face pose, using a person-specific frontal model specialized for input three-dimensional (3D) facial data. The face pose correction apparatus may comprise: a generation unit for generating corrected first facial data by performing a 3D rigid transformation of input 3D facial data on the basis of a pre-stored 3D standard facial model; and a correction unit for generating a first subject-specialized frontal model which is a bilateral symmetry model of the first facial data, and correcting the first facial data by performing the 3D rigid transformation of the first facial data on the basis of the generated first subject-specialized frontal model. L'invention concerne un appareil de correction de pose de visage destiné à corriger une pose de visage, à l'aide d'un modèle frontal spécifique à une personne spécialisé pour des données faciales tridimensionnelles (3D) d'entrée. L'appareil de correction de pose de visage peut comprendre : une unité de génération destinée à générer des premières données faciales corrigées en effectuant une transformation rigide en 3D de données faciales 3D d'entrée sur la base d'un modèle facial standard 3D pré-stocké; et une unité de correction destinée à générer un premier modèle frontal spécifique au sujet qui est un modèle de symétrie bilatérale des premières données faciales, et à corriger les premières données faciales en effectuant la transformation rigide en 3D des premières données faciales sur la base du premier modèle frontal spécifique au sujet généré. 입력받은 3차원 얼굴 데이터에 특화된 person-specific 정면 모델을 이용하여 얼굴 자세를 보정하는 얼굴 자세 보정 장치가 제공된다. 상기 장치는: 미리 저장된 3차원 표준 얼굴 모델에 기초하여 입력 3차원 얼굴 데이터를 3차원 강체변환(3D rigid transformation) 하여 보정한 제1 얼굴 데이터를 생성하는 생성부, 및 상기 제1 얼굴 데이터의 좌우 대칭 모델인 제1 대상 특화 정면모델을 생성하고, 상기 생성된 제1 대상 특화 정면모델에 기초하여 상기 제1 얼굴 데이터를 3차원 강체변환 하여 보정하는 보정부를 포함할 수 있다.
