Abstract

Embodiments of the present invention provide a method and device for tracking a conference speaker, the method is applied to a conference speech terminal, the conference speech terminal includes a ring microphone array and a pan-tilt camera, and the ring microphone array includes multiple groups of microphones; In the embodiment of the present invention, the sound source signal of the conference speaker is collected through the multiple groups of microphones; the strength of the sound source signal of the multiple groups of microphones is compared to determine the target microphone with the strongest sound source signal; query the target The position of the microphone in the ring microphone array; according to the position, adjust the shooting direction of the pan-tilt camera to shoot the conference speaker at which the target microphone is aimed, which can quickly, accurately and automatically track the conference speech It overcomes the need for frequent manual switching and focusing when switching conference speakers in the prior art, and the manual adjustment is not timely and accurate enough; the embodiment of the present invention has higher tracking accuracy.

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 ...
