分布式麦克风阵列的声源定位

声定位探测技术的无源被动特性,使其在定位技术研究领域内独树一帜,时延估计和定位算法是支持这一技术的核心。DUET时延估计算法简单,通过对接收到的信息分段帧移加窗处理,能够有效识别有用语音信息,时延估计精度较高,在高噪声的环境中非常适用;球面定位算法是基于时延估计提出的,对麦克风的排列形式不固定,适用于任意排布的麦克风阵列,并且在时延估计精度较高的情况下,能够很准确地对声源目标进行定位。

Sound Source Localization Distributed Microphone Array

Passive features of Acoustic positioning detection technology make it unique in the field of positioning technology,TDE and positioning algorithm is the core to support this technology. DUET delay estimation algorithm is simple,with segmenting information received via the docking frame shift windowing,it can effectively identify useful speech information,high delay estimation accuracy is corporately accurate which is suited in high-noise environments ideally;spherical delay estimation algorithm is put forward based on TDE ,the arrangement of the microphone is not fixed in the form of its requirements,and therefore is applicable to any arrangement of the microphone array,and in the case of high precision delay estimation,it can accurately position the sound source target.
