Abstract

The invention relates to the technical field of sound source positioning, and discloses a positioning error correction method and device based on microphone arrays, terminal equipment and a storage medium, and the method comprises the steps: obtaining current output signals of a plurality of microphone arrays; classifying the current output signals to obtain a classification result; acquiring a current position relation parameter between the microphone arrays; performing exterior point elimination on each category in the classification result to obtain an elimination result; and performing error correction on the current position relation parameter according to the elimination result. According to the invention, the problem that large errors occur in sound source positioning due to the fact that the current position relation parameters of the microphone arrays are not corrected is solved.

Description

technical field [0001] The present invention relates to the technical field of sound source localization, in particular to a microphone array-based positioning error correction method, device, terminal equipment and storage medium. Background technique [0002] In the technical field of sound source localization, multiple microphone arrays are commonly used to localize multiple sound sources. During the localization process, each microphone array will collect the output signals of multiple sound sources, and then perform sound source localization according to the output signals corresponding to the same sound source. However, when the position of a certain microphone array is moved or the swing direction is changed, if the positional relationship parameters of the microphone array are not corrected, large errors in sound source localization will occur. Contents of the invention [0003] The purpose of the embodiment of the present invention is to propose a positioning err...
