| Abstract;Due to the limitation of display size or resolution of traditional TV conference systems, we can not see detailed expression on speaker's face shown on a TV screen, or can not even see who is speaking from the remote site. Last year, we developed a TV conference system where a speaker was automatically identified and his/her face was zoomed in on the TV screen, so that remote participants could better read speaker's facial expression. Speakers were identified with a microphone array, and speakers' images were extracted from two fixed DV cameras. When using the system, however, system administrators had to manually perform a burdensome camera calibration task prior to the conferences. In the task, image positions on the two DV cameras and angles from the microphone array must be precisely corresponded. In this paper, we propose a camera calibration mechanism using omnidirectional cameras. After introducing the mechanism, one person can easily and accurately perform the calibration task that formerly required more than two people. (author abst.) |
