Patent ID: 7586513

Claim:
A method of localizing a position of an audio source relative to a camera, comprising steps of: determining a position of the audio source relative to at least one of a microphone and array of microphone elements; geometrically deriving, by a control unit, a second distance and direction between the camera and one of the at least one of the microphone and array of microphone elements; and geometrically deriving, by the control unit through a mathematical analysis, a first distance and direction between the camera and the audio source, for a system wherein a distance between the at least one of the microphone and array of microphone elements and the camera is greater than a distance between the audio source and the at least one of the microphone and array of microphone elements, from the position of the audio source relative to one of the at least one the microphone and array of microphone elements and said second distance and direction, wherein said step of geometrically deriving said second distance or direction between the camera and one of the at least one of the microphone and array of microphone elements, further comprises: transmitting a sound signal generated by a machine from a known or detectable position relative to the camera; respectively receiving the sound signal in at least two of the microphones and arrays of microphone elements; and processing the received sound signals for calculating said second distance or direction between the camera and one of the at least one of the microphone and array of microphone elements, wherein the at least one of the microphone and array of microphone elements is remote from the camera.
