Abstract

The invention discloses a facial pose estimation method and device, and the method comprises the steps: obtaining a plurality of key points of a human face in a to-be-detected image; determining two-dimensional and three-dimensional coordinates corresponding to the plurality of key points; determining a weak perspective projection matrix according to the two-dimensional and three-dimensional coordinates; and determining the facial pose estimation result of the human face according to the weak perspective projection matrix. The method and device can simplify a calculation process of determining a perspective projection matrix in the related technology into a calculation process of determining the weak perspective projection matrix, thereby determining the facial pose estimation result according to the weak perspective projection matrix, and speeding up the calculation.

Description

technical field [0001] The present disclosure relates to the communication field, and in particular, to a method and device for estimating a human face pose. Background technique [0002] At present, face pose estimation plays an important role in the fields of face recognition and human-computer interaction. Face pose estimation is to estimate the pose of the face in the 2D image in the 3D space. However, in the related art, when performing face pose estimation, the calculation process involved is cumbersome and the calculation speed is slow. Contents of the invention [0003] In view of this, the present disclosure provides a face pose estimation method and device to solve the problems of cumbersome calculation process and slow calculation speed in face pose estimation in the related art. [0004] According to a first aspect of an embodiment of the present disclosure, a method for estimating a face pose is provided, the method comprising: [0005] Obtain multiple key ...
