Self-discovery method and apparatus |
摘要 |
A method of self-discovery and self-calibration is provided for allowing arbitrary placement of audio and video components in a multimedia conferencing system. In particular, one or more markers are provided on the audio components (e.g. microphone arrays, etc.) that are detectable by the video components (e.g. cameras). A unique signature (e.g. flashing sequence, colour, etc.) characterizes each marker so that its exact location relative to the camera may be calculated. A self-calibration operation is then performed to relate, regulate and standardize dimensions and locations in the conferencing environment to the video system. <IMAGE> |
