Abstract
(EN)
This acoustic recognition device (100) comprises: at least two microphones (1); an orientation detection unit (4) which detects the orientation of the microphone (1); a self-position estimation unit (52) which estimates a position of the microphone (1) on the basis of the orientation of the microphone (1) and a signal of sound detected by the microphone (1); a sound source estimation unit (53) which estimates a direction of a sound source (200), on the basis of the orientation of the microphone (1) and the signal of the sound detected by the microphone (1); and a sound environment mapping unit (54) which creates a sound environment map in which at least the position of the sound source (200) is displayed, on the basis of the position of the microphone (1) estimated by the self-position estimation unit (52) and the direction of the sound source (200) estimated by the sound source estimation unit (53).
(FR)
L'invention concerne un dispositif de reconnaissance acoustique (100) comprenant : au moins deux microphones (1) ; une unité de détection d'orientation (4) qui détecte l'orientation du microphone (1) ; une unité d'estimation d'auto-position (52) qui estime une position du microphone (1) sur la base de l'orientation du microphone (1) et d'un signal de son détecté par le microphone (1) ; une unité d'estimation de source sonore (53) qui estime une direction d'une source sonore (200), sur la base de l'orientation du microphone (1) et du signal du son détecté par le microphone (1) ; et une unité de cartographie d'environnement sonore (54) qui crée une carte d'environnement sonore dans laquelle au moins la position de la source sonore (200) est affichée, sur la base de la position du microphone (1) estimée par l'unité d'estimation d'auto-position (52) et de la direction de la source sonore (200) estimée par l'unité d'estimation de source sonore (53).
(JA)
音響認識装置(100)は、少なくとも2本のマイク(1)と、マイク(1)の姿勢を検出する姿勢検出部(4)と、マイク(1)の姿勢とマイク(1)によって検出された音の信号とに基づいて、マイク(1)の位置を推定する自己位置推定部(52)と、マイク(1)の姿勢とマイク(1)によって検出された音の信号とに基づいて、音源(200)の方向を推定する音源推定部(53)と、自己位置推定部(52)によって推定されたマイク(1)の位置と、音源推定部(53)によって推定された音源(200)の方向とに基づいて、少なくとも音源(200)の位置が表示されたマップである、音環境マップを作成する音環境マッピング部(54)と、を備える。
