基于能量衰减的增量式声源跟踪算法研究

声源定位属于典型的被动定位,基于声源定位与跟踪在实际中具有广泛的应用。文中利用声音随距离的能量衰减模型,提出了最小二乘的增量式声源跟踪算法形式,并在二维空间分别给出了声源的定位,位置式及增量式声源跟踪算法的实验结果。位置式及增量式声源跟踪算法是跟踪算法的两种表现形式,实际中可根据跟踪算法的复杂度和具体的控制对象进行选择。由于只需计算声源移动增量,与传统的位置式算法相比,增量式声源位置跟踪算法具有控制器调整方便、容错性强等特点。

Research on Incremental Tracking Algorithm of Sound Source Based on Energy Attenuation

Sound source localization is typical passive method and has widely used in application. In this paper,using the energy attenuation model of sound to distance,propose the algorithm of incremental form of the sound source tracking with the least square,and give the positioning of the sound source in two- dimensional space,and the experimental results of sound source algorithm with the positioning and increment. The positioning and incremental sound source tracking algorithm are two forms of tracking algorithm,which can be selected according to the actual tracking complexity and specific control objects. Because of only calculating the increment of the moving source,compared with the conventional position- type algorithm,the incremental tracking algorithm has the characteristics that controller is easy to adjust,the fault- tolerant performance is well.
