AUTO-CALIBRATION OF RELATIVE POSITIONS OF MULTIPLE SPEAKER TRACKING SYSTEMS

A system that automatically calibrates multiple speaker tracking systems with respect to one another based on detection of an active speaker at a collaboration endpoint is presented herein. The system collects a first data point set of an active speaker at the collaboration endpoint using at least a first camera and a first microphone array. The system then receives a plurality of second data point sets from one or more secondary speaker tracking systems located at the collaboration endpoint. Once enough data points have been collected, a reference coordinate system is determined using the first data point set and the one or more second data point sets. Finally, after a reference coordinate system has been determined, the system generates the locations of the one or more secondary speaker tracking systems with respect to the first speaker tracking system.
