Title:
THREE-DIMENSIONAL FACE SHAPE DERIVATION DEVICE, THREE-DIMENSIONAL FACE SHAPE DERIVING METHOD, AND NON-TRANSITORY COMPUTER READABLE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2019/078310
Kind Code:
A1
Abstract:
A three-dimensional face shape derivation device (300) includes: a face image acquisition unit (301) that acquires a plurality of image frames capturing the face of a subject; a face information acquisition unit (302) that acquires face information indicating respective positions of a prescribed number of face characteristic points of the face of the subject in each of the image frames, the prescribed number of face characteristic points necessary for deriving the three-dimensional shape of the face of the subject being set in advance; and a three-dimensional shape derivation unit (303) that associates the respective face characteristic points of the face of the subject among the plurality of image frames on the basis of the face information of each of the image frames, and derives the three-dimensional shape of the face of the subject on the basis of the association result.
