Abstract

The invention discloses a picture tracking method and device for a video conference. The method comprises the following steps: firstly, acquiring image information and to-be-positioned sound information of a video conference; performing image processing on the image information of the video conference to obtain position distribution data of participants; performing sound positioning processing onthe to-be-positioned sound information to obtain position information of sound; determining position information of a person matched with the to-be-positioned sound information according to the position information of the sound and the position distribution data of the participants; and generating a close-up image corresponding to the position information of the person. According to the technicalscheme, the accuracy of outputting the close-up picture by a close-up lens and the output speed of the close-up picture can be improved, so that the communication efficiency of a video conference is improved.

Description

technical field [0001] The invention relates to the technical field of video conferencing, in particular to a method and device for tracking images of a video conference. Background technique [0002] When using a video conferencing terminal for a multi-person video conference, it is often necessary to output a close-up shot of a certain speaker, so as to improve the communication efficiency of the video conference. [0003] There are two existing video close-up output methods. One is to realize the output of close-up shots through a camera with multiple preset positions. The specific steps are as follows: first, configure a certain number of preset positions for the camera; secondly, , when the lecturer switches, the moderator or conference assistant manually adjusts the camera to its adjacent preset position; finally, fine-tunes the camera so that the camera is aimed at the lecturer, thereby outputting a close-up shot. However, this method requires manual adjustment, whic...
