Document Type and Number:
Japanese Patent JP7304603
Kind Code:
B2
Abstract:
A human detection system (10) includes: an extractor (11) that extracts, at predetermined time intervals, a heat source region equivalent to a human body from heat source regions in a room detected by a heat source detector (20); and a human detector (12) that detects, at the predetermined time intervals, a heat source region of a human body in the room, and the human detector (12) calculates a first heat source region by deleting an overlapping region of the latest human body-equivalent heat source region and the preceding human body-equivalent heat source region from the latest human body-equivalent heat source region, the latest human body-equivalent heat source region being a heat source region equivalent to a human body that is currently extracted by the extractor (11), the preceding human body-equivalent heat source region being a heat source region equivalent to a human body that is previously extracted by the extractor (11), calculates a second heat source region by adding the first heat source region calculated and a human body heat source region being a heat source region of a human body that is previously detected by the human detector (12), calculates a third heat source region being an overlapping region of the latest human body-equivalent heat source region and the second heat source region calculated, and detects the third heat source region calculated as the heat source region of a human body in the room.
