MULTI-SOUND SOURCE LOCATION TRACKING DEVICE AND A LOCATION TRACKING METHOD THEREOF FOR ESTIMATING A DIRECTION OF MULTI-SOUND SOURCE USING A MICROPHONE ARRAY

摘要

PURPOSE: A multi-sound source location tracking device and a location tracking method thereof are provided to rapidly and accurately track a location of multi-sound source after collecting sound source candidates by iterating a work searching for a sound candidate by predetermined frame of a signal of microphone.;CONSTITUTION: A multi-sound source location tracking device includes a microphone array(10) consisting of a plurality of microphones receiving a sound signal, a sound source tracking unit(20) estimating a location of actual sound sources using the verified result through beamforming after extracting sound source candidates, a sound source candidate extraction unit(30) extracting a plurality of sound source candidates and a sound source candidate verification unit(40) verifying sound source candidates of which signal intensity is greater than a predetermined value.;COPYRIGHT KIPO 2013;[Reference numerals] (20) Sound source tracking unit; (30) Sound source candidate extraction unit; (40) Sound source candidate verification unit
