To provide a facial feature detection apparatus capable of more accurately estimating the position of a facial feature.SOLUTION: A facial feature detection apparatus 10 comprises: a feature part sensor for acquiring information on a feature part of a target person; a feature part detection unit 12 for detecting the feature part on the target person's face from the information about the feature part of the target person acquired by the feature part sensor; a three-dimensional coordinate calculation unit 13 for calculating the three-dimensional coordinates of the feature part of the target person; and a feature part position estimation unit 15 for estimating the three-dimensional coordinates of a second feature part based on the three-dimensional coordinates of the first feature part detected by the feature part detection unit using the fact that the feature part of the target person exists symmetrically, wherein the second feature part exists symmetrically with the first feature part.SELECTED DRAWING: Figure 6
【課題】顔の特徴部の位置をより正確に推定することができる顔特徴部検出装置を提供する。【解決手段】顔特徴部検出装置10は、対象者の特徴部に関する情報を取得する特徴部センサと、特徴部センサが取得した対象者の特徴部に関する情報から対象者の顔の特徴部を検出する特徴部検出部12と、対象者の特徴部の三次元座標を算出する三次元座標算出部13と、対象者の特徴部が左右対称に存在することを利用して、特徴部検出部が検出した第一の特徴部の三次元座標に基づいて、該第一の特徴部と左右対称な位置に存在する第二の特徴部の三次元座標を推定する特徴部位置推定部15と、を有する。【選択図】図6
