Abstract

The invention provides a sound source localization method, device, equipment and storage medium, belonging to the technical field of audio and video signal processing. The sound source localization method, device, equipment and storage medium provided by the present invention, after initially determining the location of the current speaking object according to the received voice signal, can be based on the object's appearance or feature extracted from the image collected by the image collector Action information to further determine the exact location of the current speaking object, realize precise positioning, improve the accuracy of positioning, so that the speaking object can be placed in the middle of the playback screen more accurately, so that the audience can watch the speaking object more clearly.

Description

technical field [0001] The present invention relates to the technical field of audio and video signal processing, in particular to a sound source localization method, device, equipment and storage medium. Background technique [0002] At present, sound source localization technology is widely used in monitoring and identification systems, video conferencing systems, multimedia systems, and robots in security departments. For example, in a video conferencing system, the position of the speaking object can be determined through the sound source localization technology, so as to control the camera to turn to the speaking object, track the speaking object, and display the speaking video of the speaking object in real time. [0003] The basic flow of the existing sound source localization is generally as follows: first, a certain receiver is used to detect and collect sound signals, and preprocessing is performed on the collected sound signals to improve the quality of the sound ...
