Face 3D shape estimation device, face 3D shape estimation method, and face 3D shape estimation program

摘要

The face three-dimensional shape estimation device (300) is necessary for estimating the three-dimensional shape of the target person's face and the face image acquisition unit (301) that acquires a plurality of image frames showing the target person's face. A predetermined number of face feature points are set in advance, and face information acquisition that acquires face information indicating the position of each of a predetermined number of face feature points of the subject's face on the image frame for each of a plurality of image frames. Based on the face information of each of the part (302) and the plurality of image frames, each of the predetermined number of face feature points of the target person's face is associated between the plurality of image frames, and the result of the association is obtained. Based on this, a three-dimensional shape estimation unit (303) that estimates the three-dimensional shape of the subject's face is included.
