Abstract

The embodiment of the invention provides a conference speaker tracking method and device, the method is applied to a conference speaking terminal, the conference speaking terminal comprises an annularmicrophone array and a holder camera, and the annular microphone array comprises a plurality of groups of microphones. According to the embodiment of the invention, sound source signals of conferencespeakers are acquired through the plurality of groups of microphones; the sound source signal intensities of the plurality of groups of microphones are compared, and a target microphone with the strongest sound source signal is determined; the position of the target microphone is inquired in the annular microphone array; according to the position, the shooting direction of the pan-tilt camera isadjusted to shoot the conference speaker aligned with the target microphone, the conference speaker can be quickly, accurately and automatically tracked, and the problems that in the prior art, when the conference speaker is switched, frequent manual switching and focusing are needed, and manual adjustment is not timely and accurate are solved. The embodiment of the invention has relatively high tracking precision.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a method and device for tracking conference speakers, and a computer-readable storage medium. Background technique [0002] In a round table conference, each member needs to make a speech frequently. In a video conference, it is necessary to constantly change the speaking members that the microphone and camera are aimed at. However, frequent manual switching and focus adjustment in the prior art are It is very inconvenient, and the manual adjustment is not timely and accurate enough. How to quickly complete the speaker camera tracking while ensuring the accuracy is a problem that needs to be solved at present. Contents of the invention [0003] In view of the above problems, embodiments of the present invention are proposed to provide a conference speaker tracking method, a conference speaker tracking device, and a computer-readable storage device that overcome ...
