Abstract

The present disclosure relates to a face tracking method, device, electronic equipment and storage medium, and belongs to the technical field of computers. The method includes: tracking the motion of the target object based on a plurality of cameras to obtain a plurality of human face image sets; obtaining a target human face model based on the target human face set without facial expressions of the target object; , determine a plurality of face tracking points; based on the optical flow characteristics of each face image in the plurality of face image sets, perform optical flow tracking on the plurality of face tracking points, and obtain the plurality of face tracking points in each face image The two-dimensional coordinates in; based on the two-dimensional coordinates of the plurality of facial tracking points in each human face image, determine the three-dimensional coordinates of the plurality of facial tracking points in each human face model. The face tracking points selected from the vertices of the target face model in the present disclosure have pixel-level tracking accuracy, thereby improving the accuracy of face tracking.

Description

Technical field [0001] The present disclosure relates to the field of computer technology, and more particularly to a human face tracking method, device, electronic device, 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 identification technology identified based on human face feature information. On the basis of face recognition, you can track your face tracking, that is, a face tracking. [0003] At present, the timing three-dimensional face scan technology can be used to efficiently capture the face geometric information, and in order to establish the timing correlation of the facial geometry, it is necessary to apply a special facial markup in the face of the collector, and then multi-angle. The labeled point PS (Photoshop, an image processing application) in the texture map (Photoshop, an image processing application) scanned out of the face ...
