Abstract

The invention provides a method, a device and a system for positioning a sound source. The method comprises the following steps: acquiring the signal of each microphone in a microphone array, wherein the microphone array is used to collect the sound of a sound source; acquiring controllable power responses of multiple microphone pairs composed of the microphones according to the framing of the signals; acquiring the sum of the controllable power responses of the multiple microphone pairs, and determining the direction angles of the sound source and the microphone array according to the maximum value of the sum of the controllable power responses; and determining the relative position relationship between the microphone array and the sound source according to the direction angles. The problem that the existing controllable power response technology is of low resolution and high computation burden is solved. The real-time performance, stability and accuracy of sound source positioning are improved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a sound source localization method, device and system. Background technique [0002] During the video conference, it is necessary to focus on shooting the speaker to obtain important information such as his body language and facial expression. When the speaker is not within the camera range, the traditional method is to manually use the remote control to control the rotation of the camera so that the speaker is within the camera range; especially when the speaker changes frequently, this manual method is very inconvenient, and Important information will be lost due to delayed operation. The camera that automatically tracks the speaker can make up for the above shortcomings and bring a better experience to both participants. [0003] Cameras that track speakers use sound localization technology. Calculating the direction of sound source by using microphone array is the basic ...
