Abstract

The invention provides a sound source positioning method and device and electronic equipment, and relates to the field of target positioning. The sound source positioning method comprises the following steps: firstly, determining a first transmission time when a user voice is transmitted to each fixed microphone and a second transmission time when a first voice signal is transmitted to a sound console; then, respectively determining a first distance between the target microphone and each fixed microphone and a second distance between the target microphone and the sound console according to the first transmission time and the second transmission time; and finally, according to the position coordinates of each fixed microphone and the sound console, the first distance and the second distance, determining the position coordinate of the target microphone, and further adjusting the shooting angle of the camera. Accurate positioning of the mobile spokesman with an unfixed position in a large conference scene is realized, the flexibility and accuracy of spokesman positioning are improved, and the conference effect is improved.

Description

【Technical field】 [0001] The present application relates to the technical field of target positioning, and in particular to a sound source localization method, device and electronic equipment. 【Background technique】 [0002] In a video conferencing scenario, in order to provide a good conference effect, when a speaker speaks, it is necessary to point a camera at the speaker to take pictures of the speaker. [0003] At present, the methods for aiming the camera at the speaker mainly include: Method 1, using a camera, setting multiple shooting angles for the camera in advance, and each shooting angle corresponds to a position of the speaker. When a speaker is speaking, use the shooting angle corresponding to the position of the speaker to shoot. Method 2: Use multiple cameras, set a shooting angle for each camera in advance, and the shooting angle of each camera corresponds to a speaker position. When a speaker speaks, the camera corresponding to the speaker's position is us...
