Title:
SOUND SOURCE LOCATION ESTIMATION DEVICE AND ROBOT COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2020/022555
Kind Code:
A1
Abstract:
A sound source location estimation device, according to one embodiment of the present invention, comprises a first array unit and a second array unit. The first array unit detects a sound from an arbitrary sound source, and comprises: a first center unit; and a plurality of receiving units each arranged at the same distance from the first center unit. The second array unit detects the sound of the sound source, and comprises: a second center unit; and a plurality of receiving units each arranged at the same distance from the second center unit. The first array unit and the second array unit are spaced apart by a predetermined distance so that the first center unit and the second center unit face each other. The sound source location estimation device, according to the present invention, calculates the azimuth angle and elevation angle of the sound source by using a signal of the sound detected by the plurality of receiving units, and estimates the location of the sound source by means of the azimuth angle and elevation angle.
