摘要
从系统的角度对真实声场环境下基于到达时间差的声源定位算法进行了研究,搭建了基于麦克风阵列的声源定位系统,将LabVIEW应用于声源定位软件的开发,方便地完成信号的采集与处理,运用广义互相关函数法进行时延估计,结合平面四元十字阵模型建立方程组实现定位。该系统人机界面友好,具有较强的数据分析和处理能力,能及时跟踪声源的位置变化。
Acoustic source localization algorithm based on time difference of arrivals（TDoA） in the real acoustic field environment is studied from the systematic point of view.Acoustic source localization system based on microphone array is constructed.LabVIEW is applied to develop the corresponding software,which makes the signal acquisition and processing convenient.Generalized mutual correlation function is used to estimate the time delay of arrival,and four-element planar crossing array model is also utilized to set up equation set and implement localization.The system possesses strong ability of data analyzing and processing with friendly GUI,timely tracking the changing location of the acoustic source.
