一种基于麦克风阵列的声源定位算法研究
Research on Acoustic Source Localization Algorithm Using Microphone Array
摘要
Abstract
The acoustic source is widely used in audio and video conference system and gunshot localization system. In this article, a novel acoustic source localization algorithm for microphone array based on minimum entropy and stochastic region contraction (ME) is proposed. The algorithm show that the acoustic source can be developed to estimate time delay between microphones on a basis of minimum entropy and localize the acoustic source in search space by using discrete grid search algorithm. Experimental results show that the proposed algorithm is much more robust than GCOPHAT in noise and reverberation environment.关键词
