Abstract

This paper considers the problem of constructing 2-D room shape. A mobile device with co-located microphone and loudspeaker is used and the distances between consecutive measurement points are assumed to be known. The uniqueness of the mapping between the first-order echoes and the room geometry is guaranteed for any convex polygons. A practical algorithm for room reconstruction in the presence of noise and higher order echoes is proposed. Experimental results are provided to demonstrate the effectiveness of our approach.
