Embodiment Construction

[0042] The sound source localization method and device disclosed in the embodiments of the present application can be applied to scenarios including microphone arrays and cameras, such as whistle-blowing snapshots, speaker-person and human-face snapshots, and the like. The purpose is to determine the final position information of the sound source by fusing the position information of the sound source determined by the microphone array and the position information of the target determined by the camera, so as to improve the accuracy of sound source localization. The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making c...

Abstract

The invention provides a sound source locating method and device. The method includes the steps of determining first position information of a target relative to a camera according to a target image,obtaining second position information determined according to sound signals, and determining position information of a sound source according to the first position information and the second positioninformation, wherein the difference value of the collecting time of the sound signals and the collecting time of the image is not larger than a preset first threshold. It can be seen that when the position information of the target is determined through the position information determined according to the image and the position information determined according to an audio, compared with the mode of locating the position of the sound source only through a microphone array, the locating result has higher accuracy.

Description

technical field [0001] The present application relates to the technical field of target tracking, in particular to a sound source localization method and device, and a target capture system. Background technique [0002] Sound source localization is a technique to determine the position of sound-emitting objects (ie, sound sources) based on sound signals. Sound source localization technology can be used to meet various needs, such as whistle capture, target tracking, etc. [0003] At present, the sound source localization by using a microphone array is the most common sound source localization method, but the accuracy of this sound source localization method needs to be improved. Contents of the invention [0004] The present application provides a sound source localization method and device, and a target capture system, aiming at solving the problem of how to improve the accuracy of sound source localization results. [0005] In order to achieve the above object, the ap...
