摘要
采用基于时延估计(Time Delay Estimation,TDE)的声源定位技术,估计出目标声源到达不同麦克风阵元间的时间差,并结合平面五元十字阵的几何定位模型算法确定了声源位置。针对目前基于传声器阵列声源定位系统定位精度有待进一步提高的问题,提出一种新的定位算法,利用组合传声器阵列阵元相互之间几何位置关系,即通过多个传声器,多方向估计,多个阵列之间综合考虑,确定具有较高精度的声源位置。
Based on time delay estimation（TDE） sound source localization technology is adopted, it can be estimated the target source to the time difference between the different microphone arrays, and the location of the sound source is determined by the geometric; localization model of the five-element planar crisscross array. A new localization algorithm was put forward aiming at the current sound source localization based on microphone array system needs to be further improved positioning acxmracy problem, using combination microphone array element between the geometric relation, namely through a plurality of microphones, multi-direction estimation, multiple array between comprehensive consideration, to determine with high precision the location of the sound source .
