Title:
ARTIFICIAL INTELLIGENCE METHOD AND APPARATUS FOR MONITORING SCENE RECOGNITION ACOUSTIC CONDITION HAVING HIGH SIGNAL-TO-NOISE RATIO
Document Type and Number:
WIPO Patent Application WO/2023/287149
Kind Code:
A1
Abstract:
The present invention relates to a high-performance artificial intelligence method for monitoring a scene recognition acoustic condition having a high signal-to-noise ratio, comprising: a visual image acquisition step (S10) in which an image generating unit (10) generates a visual image for a scene by capturing the scene with an optical camera; a part objective recognition step (S20) in which an AI part image recognizing unit (30) recognizes a part objective in the visual image by using an artificial intelligence means; an acoustic signal regeneration step (S30) for regenerating, from acoustic signals acquired for the scene with an acoustic sensor array (15), an acoustic signal of an area where the part objective is located by using a beam forming technique; a step (S40) for repeating the visual image acquisition step (S10), the part objective recognition step (S20), and the acoustic signal regeneration step (S30) at different times; and an acoustic condition monitoring step (S50) in which a condition monitoring unit (60) monitors an acoustic condition of the part objective by comparing and analyzing regenerated acoustic signals that are generated and stored in different time periods for a specific (one or same) part objective, the identity of which is recognized.
