Title (EN) SOUND SOURCE POSITION ESTIMATING DEVICE AND WEARABLE DEVICE
(FR) DISPOSITIF D'ESTIMATION DE POSITION DE SOURCE SONORE ET DISPOSITIF VESTIMENTAIRE
(JA) 音源位置推定装置及びウェアラブルデバイス
Abstract:
(EN) [Problem] To enable, even when displacement in wearing of a wearable device has occurred, estimation of the position of a sound source resulting from the displacement. [Solution] The sound source position estimating device according to the present disclosure is provided with: a spectrum acquiring unit that acquires, on the basis of a sound obtained by a plurality of microphones provided to a ring-shaped wearable device, the frequency spectrum of a sound source; a distance calculating unit that calculates the respective distances from the plurality of microphones to the sound source on the basis of the frequency spectrum; and a sound source position calculating unit that approximates the ring-shaped wearable device to a circle, assumes that the sound source is positioned on a cylindrical surface including the ring-shaped wearable device, obtains the point of intersection between the cylindrical surface and a spherical surface, diameters of which are the respective distances, and thereby, calculates the position of the sound source.
(FR) Le problème décrit par la présente invention est de permettre, même lorsqu'un déplacement s'est produit dans le port d'un dispositif vestimentaire, l'estimation de la position d'une source sonore résultant du déplacement. La solution de la présente invention concerne un dispositif d'estimation de position de source sonore comprenant : une unité d'acquisition de spectre qui acquiert, sur la base d'un son obtenu par une pluralité de microphones disposés sur un dispositif vestimentaire en forme d'anneau, le spectre fréquentiel d'une source sonore ; une unité de calcul de distance qui calcule les distances respectives de la pluralité de microphones à la source sonore sur la base du spectre fréquentiel ; et une unité de calcul de position de source sonore qui assimile le dispositif vestimentaire en forme d'anneau à un cercle, suppose que la source sonore est positionnée sur une surface cylindrique comprenant le dispositif vestimentaire en forme d'anneau, obtient le point d'intersection entre la surface cylindrique et une surface sphérique, dont les diamètres sont les distances respectives, et calcule ainsi la position de la source sonore.
(JA) 【課題】ウェアラブルデバイスに装着ずれが発生した場合であっても、装着ずれに起因する音源の位置を推定できるようにする。 【解決手段】本開示に係る音源位置推定装置は、リング状のウェアラブルデバイスに設けられた複数のマイクロフォンで得られる音声に基づいて、音源の周波数スペクトルを取得するスペクトル取得部と、前記周波数スペクトルに基づいて複数の前記マイクロフォンから前記音源までのそれぞれの距離を演算する距離演算部と、前記リング状のウェアラブルデバイスを円に近似して、前記リング状のウェアラブルデバイスを含む円柱面に前記音源が位置するものとして、前記それぞれの距離を半径とする球面と前記円柱面との交点を求めることで前記音源の位置を演算する音源位置演算部と、を備える。
