Abstract

The invention relates to a face tracking method and device, electronic equipment and a storage medium, and belongs to the technical field of computers. The method comprises the following steps: performing motion tracking on a target object based on a plurality of cameras to obtain a plurality of face image sets; obtaining a target face model based on the target face set of the target object without the facial expression; determining a plurality of face tracking points from a plurality of vertexes of the target face model; performing optical flow tracking on the plurality of face tracking points based on optical flow features of each face image in the plurality of face image sets to obtain two-dimensional coordinates of the plurality of face tracking points in each face image; and based on the two-dimensional coordinates of the plurality of face tracking points in each face image, determining the three-dimensional coordinates of the plurality of face tracking points in each face model. The face tracking points selected from the vertexes of the target face model have pixel-level tracking precision, so that the face tracking precision can be improved.

Description

technical field [0001] The present disclosure relates to the field of computer technology, and in particular to a face tracking method, device, electronic equipment and storage medium. Background technique [0002] With the development of computer technology, face recognition has gradually become a hot technology. Face recognition is a biometric technology for identification based on human facial feature information. On the basis of face recognition, face tracking can also be performed on the recognized faces, that is, face tracking. [0003] At present, time-series 3D face scanning technology can be used to efficiently capture facial geometric information, but in order to establish the time-series correlation of facial geometry, it is necessary to smear special facial marker points on the face of the collector, and then use artificial post-processing technology to convert the multi-view The marker points PS (PhotoShop, a kind of image processing application program) in th...
