Title:
MONITORING SYSTEM AND MONITORING METHOD
Document Type and Number:
Japanese Patent JP2017028529
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To enable a user to easily visually recognize and identify a cause of a suspicious abnormal sound generated in an imaging target area even when the suspicious abnormal sound occurs in a place where the imaging target area is dim or at night.SOLUTION: In a monitoring control system 10, a camera device CA images a monitoring area 5, and a microphone array device MA collects sounds in the monitoring area 5. A sound source detector 34 in a directivity control device 30 detects the sound source direction of sounds collected by the microphone array device MA. When the sound pressure p of the sounds collected by the microphone array device MA exceeds a sound source detection threshold value, a luminaire 50 illuminates the monitoring area 5 on the assumption that abnormal sounds or alarm sounds are generated in the monitoring area 5. An output controller 35 of the directivity control device 30 generates a sound source direction image indicating the sound source direction of the abnormal sound or the warning sound, superimposes the sound source direction image on image data captured after the camera device CA switches the sound source direction to the imaging direction, and displays them on a monitoring monitor 36.SELECTED DRAWING: Figure 1
