Systems and methods for talker tracking and camera positioning in the presence of acoustic reflections

A system comprising:

• at least one microphone disposed in an environment and configured to determine sound location information for an audio source detected by the at least one microphone;
• a camera disposed in the environment and comprising an image capturing component;
• and
• one or more processors communicatively coupled to each of the at least one microphone and the camera, the one or more processors configured to:
• receive the sound location information from the at least one microphone;
• determine, based on the sound location information, a first set of coordinates representing an estimated talker location for the audio source;
• determine, based on the sound location information and a height measurement of the environment, a second set of coordinates representing a corrected talker location for the audio source;
• calculate a weighted height coordinate based on a first height coordinate of the first set of coordinates, a second height coordinate of the second set of coordinates, and stored height coordinates obtained for previously detected audio sources;
• and
• transmit, to the camera, a third set of coordinates comprising the weighted height coordinate and representing a final talker location for the audio source,
• wherein responsive to receiving the third set of coordinates, the camera is configured to point the image capturing component towards the final talker location.

A non-transitory computer-readable storage medium comprising instructions that, when executed by one or more processors in communication with each of at least one microphone, and a camera, cause the one or more processors to perform the following:

• receive sound location information for an audio source detected by the at least one microphone;
• determine, based on the sound location information, a first set of coordinates representing an estimated talker location for the audio source;
• determine, based on the sound location information and a height measurement of the environment, a second set of coordinates representing a corrected talker location for the audio source;
• calculate a weighted height coordinate based on a first height coordinate of the first set of coordinates, a second height coordinate of the second set of coordinates, and stored height coordinates obtained for previously detected audio sources;
• and
• transmit, to the camera, a third set of coordinates comprising the weighted height coordinate and representing a final talker location for the audio source, wherein receipt of the third set of coordinates causes the camera to point an image capturing component of the camera towards the final talker location.
