Claim 4:
5. The method according to claim 1, wherein the determining head rotation information of the current participant in a specified direction based on the two-dimensional positional information and the marking information of all facial structure points comprises: in the facial area of the video image, using each two-dimensional positional information as vertex position information to obtain facial mesh information, according to a connection relationship rule of the marking information; and inputting reference mesh information and the facial mesh information corresponding to the current participant into a trained neural network model to obtain the head rotation information, wherein the reference mesh information is obtained based on the two-dimensional positional information and the marking information of the facial structure points in a reference image of the current participant, and the facial structure points in the video image and the facial structure points in the reference image have a corresponding relationship with respect to the facial position of the current participant.
