| 摘 要： | 构建了一个基于四个声音传感器的信号时延采集系统,根据采集系统得到的三个时间差和传感器的响应顺序,提出了一种基于蒙特卡罗法实时空间的三维声源定位算法.该算法通过三维声音定位的非线性方程,构建一个三维模函数,通过寻找空间全局收敛点,并根据公差容限进行变步长搜索,准确快速地计算出声源的位置.

| Abstract: | A time-delay of arrival collection system is built based on the four microphone array. Real-time space 3D acoustic localization based on Monte Carlo algorithm is presented. It can quickly calculate the sound source position by using three time-delay of arrival to the microphone array. A 3D modular function is built based on the nonlinear function of acoustic localization. The sound position can be localized quickly and accurately by seeking the global convergence and altering the step length according to the tolerance of accuracy. |
