Abstract
Official abstract text for this publication.
The present invention pertains to a method for estimating a sound source position in a space with high accuracy using a microphone installed on a robot moving in the space. A mobile robot includes a self-position estimation unit configure to estimate the self-position of the mobile robot, a sound source information obtaining unit configured to obtain direction information of an observed sound source, and a sound source position estimation unit configured to estimate the position of the sound source based on the estimated self-position and the direction information of the sound source.
First claim
Opening claim text (preview).
What is claimed is: 1 . A mobile robot comprising: a self-position estimation unit configured to estimate a self-position of the mobile robot; a sound source information obtaining unit configured to obtain direction information of an observed sound source; and a sound source position estimation unit configured to estimate a position of the sound source from the estimated self-position and the direction information of the sound source. 2 . The mobile r…
