Patent attributes
Robotics visual and auditory system is provided which is made capable of accurately conducting the sound source localization of a target by associating a visual and an auditory information with respect to a target. It is provided with an audition module (20), a face module (30), a stereo module (37), a motor control module (40), an association module (50) for generating streams by associating events from said each module (20, 30, 37, and 40), and an attention control module (57) for conducting attention control based on the streams generated by the association module (50), and said association module (50) generates an auditory stream (55) and a visual stream (56) from a auditory event (28) from the auditory module (20), a face event (39) from the face module (30), a stereo event (39a) from the stereo module (37), and a motor event (48) from the motor control module (40), and an association stream (57) which associates said streams, as well as said audition module (20) collects sub-bands having the interaural phase difference (IPD) or the interaural intensity difference (IID) within the preset range by an active direction pass filter (23a) having a pass range which, according to auditory characteristics, becomes minimum in the frontal direction, and larger as the angle becomes wider to the left and right, based on an accurate sound source directional information from the association module (50), and conducts sound source separation by restructuring the wave shape of the sound source.
