Title:
HIGH-ANGLE FACIAL RECOGNITION METHOD AND SYSTEM BASED ON 3D FACIAL MODEL
Document Type and Number:
WIPO Patent Application WO/2023/019699
Kind Code:
A1
Abstract:
A high-angle facial recognition method and system based on a 3D facial model, by means of which method and system recognition is performed by rotating a clear front-on face in a facial sample library such that the clear front-on face is at the same angle as a high-angle face to be recognized. The method comprises: firstly, collecting a clear front-on facial picture, constructing a facial sample library, and generating a 3D facial model from the front-on facial picture in the sample library; then, estimating, by using a facial posture estimation algorithm, the angle of a high-angle facial picture to be recognized, and rotating the 3D facial model such that same is at the same angle as the high-angle facial picture; and finally, inputting a generated high-angle face and a high-angle face to be recognized into a facial recognition network for recognition. By means of the method, for the problem of facial recognition in an actual overhead monitoring scenario, the high-angle face recognition accuracy is significantly improved.
