Abstract
A dynamically adjustable framed view of occupants in a room is captured through an automatic framing system. The system employs a camera system, including a pan/tilt/zoom (PTZ) camera and one or more depth cameras, to automatically locate occupants in a room and adjust the PTZ camera's pan, tilt, and zoom settings to focus in on the occupants and center them in the main video frame. The depth cameras may distinguish between occupants and inanimate objects and adaptively determine the location of the occupants in the room. The PTZ camera may be calibrated with the depth cameras in order to use the location information determined by the depth cameras to automatically center the occupants in the main video frame for a framed view. Additionally, the system may track position changes in the room and may dynamically adjust and update the framed view when changes occur.
