摘要
常见的声源定位测量方法都极大依赖于测量数据的精确度,当存在误差时会导致求解的方程无解。新的声源定位方式即线—面定位,引入空间直角坐标系,利用曲面与直线的交点来确定声源位置,减少了时延测量次数,能够有效避免由于测量误差的影响导致无法求解声源位置的情况。控制立体声阵列的形状,可以提高测量精度,对噪声以及声源信号进行优化处理等。利用此模型能在误差存在的条件下实施一定范围内有效的声源定位。
Common methods for sound source localization heavily rely on the accuracy of measurement data.When errors are present,they can lead to unsolvable equations.A new sound source localization method,known as line-surface localization,utilizes a three-dimensional coordinate system to determine the position of the sound source by finding the intersection between surfaces and lines.This approach reduces the number of time delay measurements required and effectively avoids issues related to the inability to solve for the sound source position due to measurement errors.Additionally,controlling the shape of the stereo sound array can enhance measurement accuracy and optimize the processing of noise and sound source signals.With this model,effective sound source localization can still be achieved within a certain range,even in the presence of errors.
