Document Type and Number:
Japanese Patent JP6504539
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a sound collection system and a sound collection setting method that can properly form directivity at a predetermined imaging position and clearly output sounds at the predetermined imaging position even when the positional relationship between a camera and a microphone array is unknown.SOLUTION: When a microphone array device MA is secured from the rear side in a shop 10 where camera devices C1 to C4 are installed, in preset processing, sound sources are disposed at preset positions P1 to Pn as the imaging centers of the camera devices C1 to Cn, and sounds are produced. When the microphone array device MA collects sounds of a predetermined sound volume or more output from the sound sources and transmit the audio data thereof to an audio processing device 50, a sound source direction detector 52 makes a display 58 display sound source marks SD to SD4 representing the orientation directions (horizontal angle θ and vertical angle φ), thereby promoting a user to select an orientation direction and input camera information. The sound processing device 50 transmits the input camera information and the orientation direction to the microphone array device MA. The microphone array MA stores them as a preset information table 90 in the storage part 24.SELECTED DRAWING: Figure 7
