Abstract

The invention discloses a sound source positioning method and system. Through the arrangement of a sound intensity sensor group in advance, specific sound sources are arranged in various testing directions with fixed intervals by taking the sound intensity sensor group as the center in sequence, and direction feature data corresponding to the specific sound sources in the various testing directions is collected; sound intensity feature data corresponding to the specific sound sources at different distances is collected to establish the attenuation characteristic of sound intensity and transmission distance; sound intensity data corresponding to a sound source to be tested is collected, the sound intensity data and the direction feature data corresponding to the testing directions are respectively subjected to correlation analysis, and the testing direction corresponding to the maximum value of correlation results is determined as the direction of the sound source to be tested; according to the sound intensity data and the attenuation characteristic, the distance between the sound source to be tested and the sound intensity sensor group is determined. The sound source positioning is realized by adoption of methods of feature matching of the sound source direction and the attenuation characteristic of the sound source distance, the implementation difficulty of sound source positioning is reduced, and meanwhile the positioning accuracy and the stability are improved.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a sound source localization method and system. Background technique [0002] Sound is a way of information interaction. Since sound can spread freely and fast in the medium, sound has been widely used in the field of information interaction. In recent years, with the development of science and technology, intelligent equipment has gradually entered our lives. Most of the information interaction between intelligent devices and people still relies on the mobile platform to exchange information with smart devices through the network. However, this method has gradually highlighted its disadvantages. On the one hand, mobile phones and smart devices must be configured to the network; on the other hand, mobile phone platforms need to be used to control them manually. These disadvantages greatly reduce the user experience. Gradually, people hope that smart devices can a...
