Title (EN) METHOD AND APPARATUS FOR LOCATING MOVING SOUND SOURCE
(FR) PROCÉDÉ ET APPAREIL DE LOCALISATION DE SOURCE SONORE MOBILE
(ZH) 一种运动声源的定位方法和定位装置
Abstract:
(EN) A method and an apparatus for locating a moving sound source. The method for locating a moving sound source comprises: arranging at least four microphones as a microphone array (S102); collecting the sound pressure signal of a moving sound source using the microphone array, establishing a sound source searching plane (S104); obtaining an estimated position of the moving sound source by means of the sound source locating method using the time difference of arrival (TDOA) on the basis of a searching point on the sound source searching plane, calculating the deviation value between the estimated position of the moving sound source and the corresponding searching point (S106); obtaining the position of the corresponding searching point when the deviation value is at the minimum, using the position of the searching point as the position of the moving sound source (S108).
(FR) La présente invention concerne un procédé et un appareil de localisation d’une source sonore mobile. Le procédé de localisation d’une source sonore mobile comprend : l’agencement d’au moins quatre microphones sous la forme d’un réseau de microphones (S102) ; la collecte du signal de pression sonore d’une source sonore mobile au moyen du réseau de microphones, l’établissement d’un plan de recherche de source sonore (S104) ; l’obtention d’une position estimée de la source sonore mobile au moyen du procédé de localisation de source sonore au moyen de la différence de temps d’arrivée (TDOA) sur la base d’un point de recherche sur le plan de recherche de source sonore, le calcul de la valeur d’écart entre la position estimée de la source sonore mobile et le point de recherche correspondant (S106) ; l’obtention de la position du point de recherche correspondant lorsque la valeur d’écart est au minimum, au moyen de la position du point de recherche en tant que position de la source sonore mobile (S108).
(ZH) 一种运动声源的定位方法和定位装置,其中,该运动声源的定位方法包括:将至少四个传声器布置成传声器阵列(S102);用传声器阵列采集运动声源的声压信号,并建立声源搜索面(S104);基于声源搜索面上的搜索点,利用声达时间差的声源定位方法得出运动声源的估计位置,并计算运动声源的估计位置与对应的搜索点之间的偏差值(S106);得出偏差值最小时所对应的搜索点的位置,将该搜索点的位置作为运动声源的位置(S108)。
