Titel
Reflector localization based on multiple reflection points
Abstract
Reflector localization has been the subject of growing research interest in recent years. This paper outlines an approach that performs reflector localization based on loudspeaker and microphone positions and their images. The positions of the latter are computed using pre-grouped sets of times of arrival (TOAs) estimated from room impulse responses. First, the TOA sets are used to estimate the microphone positions. Second, these are used with knowledge of the array geometry to determine the locations of reflection points on the available reflectors. Finally, the reflection points are used to obtain the reflector locations. It is shown that the proposed approach facilitates solving the reflector localization problem in ill-conditioned setups.
