Title: AUDIO SIGNAL, IMAGE PROCESSING METHOD, DEVICE, AND SYSTEM
Abstract:
The present invention provides an audio signal, image processing method, device, and system. The image processing method comprises: computing, according to a first preconfigured algorithm, and based on audio signals acquired by a plurality of microphones, a first predicted location of an object to be detected; filtering, according to a second preconfigured algorithm, location history of the object to be detected, and computing, according to the filtered location history, a second predicted location of the object to be detected; performing correction according to timing continuity of the audio signal, and the first predicted location and the second predicted location, so as to obtain a current location of the object to be detected. The embodiment resolves a problem of being unable to display in real time a location of a speaker and track and acquire multimedia information of the speaker in a remote video conference system, owing to the lack of a technology of tracking a speaker location, and achieves the effect of real-time acquisition of a speaker location, speaker tracking, and multimedia information acquisition.
