Title:
PERSON-DETECTING SYSTEM, DETECTION METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2022/176732
Kind Code:
A1
Abstract:
A person-detecting system (10) comprises: an extraction unit (11) that, at each occurrence of a prescribed time, extracts a human body-equivalent heat source region from heat source regions inside of a room as detected by a heat source-detecting unit (20); and a person-detecting unit (12) that, at each occurrence of a prescribed time, detects a heat source region of a human body inside of the room. The person-detecting unit (12): calculates a first heat source region in which an overlapping region has been deleted from a latest human body-equivalent heat source region, the overlapping region being where the latest human body-equivalent heat source region, which is the most recently-extracted human body-equivalent heat source region that was extracted by the extraction unit (11), overlaps a previous human body-equivalent heat source region, which is the human body-equivalent heat source region that was extracted by the extraction unit (11) the previous time; calculates a second heat source region in which the calculated first heat source region and a human body heat source region, that is the heat source region of a human body that was detected by the person-detecting unit (12) the previous time, have been added together; calculates a third heat source region which is an overlapping region where the latest human body-equivalent heat source region overlaps the calculated second heat source region; and detects the calculated third heat source region as a heat source region of a human body inside of the room.
