Abstract

The invention discloses a face recognition method and system based on SFM reconstruction, and solves the problem of low multi-pose face recognition rate and accuracy through the combination of three-dimensional face reconstruction and recognition. The problems of running speed and mismatching are effectively solved by adopting a stereo matching method and combining an SFM algorithm. Image reconstruction information can be accurately obtained by using a mobile phone camera, and a multi-view image of an interested object is processed by using a mixed feature extraction technology; three-dimensional face reconstruction is realized based on a two-dimensional face picture, and the mismatching rate is reduced by combining rough matching and fine matching, so that the accuracy of an SFM algorithm is improved; a required matching point is quickly and accurately found out by using an SFM algorithm, and a realistic three-dimensional face structure is obtained through subsequent processing. The three-dimensional face is used as a verification means, so that the reliability of face recognition is improved, and the method and the system can be well applied to scenes of face scanning payment, face recognition and the like.

Description

technical field [0001] The present disclosure relates to the field of computer vision technology and three-dimensional image reconstruction technology, and in particular to a face recognition method and system based on SFM reconstruction. Background technique [0002] 3D face reconstruction can be divided into 3D face reconstruction based on hardware such as: stereo camera, structured light or 3D laser scanner, which can obtain accurate 3D face data, but requires more cost. Therefore, a method based on a monocular camera is proposed to reconstruct 3D faces, which can be reconstructed from multi-view facial images. [0003] Robust algorithms are required for changes in lighting, changes in camera focal length and position, facial expressions or head shaking. At the same time, using the 3D face parametric model and the 2D face parametric texture model to render a new face image, it is necessary to manually identify the possible face areas in the image; after some improvements...
