MICROPHONE ARRAY POSITION CALIBRATION

Automatic Position Calibration of Multiple Microphones Vikas C. Raykar and Ramani Duraiswami, In Proceedings of International Conference on Acoustics, Speech and Signal Processing (ICASSP 2004),  Montreal, Canada, May 2004, vol. IV, pp. 69-72   [ Slides ]

In ad-hoc deployed microphone arrays it is rather tedious and very often not accurate to get the microphone positions manually using a tape or laser devices. Also the geometry of the array may change over time frequently either accidently or due to re-deployment. So automatic position calibration of multiple microphones is very essential. In this paper we propose a method to automatically determine the three dimensional positions of multiple microphones.
