Abstract

Paper presents the audiovisual recording system, which has been implemented in the SPIIRAS smart room and provides conduct of e-learning meetings. The techniques of video tracking and sound source localization are implemented for recording AVI files of speaker messages in the room. Video processing of streams from five cameras serves for registration participants in fixed chair positions, tracking main speaker and recording view to the audience. During the experiments AVI files with speaker’s messages were recorded in a discussion work mode. After manual checking it was detected that 90% of files are files with speaker’s speech and 10% of files are false files with noises. The verification of the system was accomplished on the functional level and also the estimations of detection quality of participants, and camera pointing on speaker and speaker message had acceptable rate.
