Localization algorithm for conferencing |
摘要 |
A conferencing device and method of talker localization for steering a plurality of sensors arranged in sectors around a housing to a current active direction beam. A beamformer is implemented for determining a loudest sector based on signals from the sensors. In the event the loudest sector persists for a first duration then forming signal beams from sensor signals in the loudest sector and a plurality of adjacent sectors over a further duration to create respective signal beam envelopes. Then selecting a highest energy of the beam envelopes to be a loudest non-active beam and comparing the loudest non-active beam to the current active direction beam. If the highest energy one of the beams is greater than the energy of the current active direction beam by a threshold, then selecting the highest energy one of the beams to be the current active direction beam and directing the sensors thereto. |
