BODY TEMPERATURE ESTIMATING DEVICE AND BODY TEMPERATURE ESTIMATING METHOD
A body temperature estimating device includes a visible light transmissive member, a wearing member, a sensor, and a processing unit. The visible light transmissive member transmits visible light and reflects infrared light. The wearing member is worn by a wearer. The wearing member holds the visible light transmissive member so as to be disposed in front of eyes of the wearer. The sensor detects infrared light emitted from the wearer of the wearing member and reflected by the visible light transmissive member. The processing unit estimates a body temperature of the wearer on the basis of the infrared light detected by the sensor.
1 . A body temperature estimating device comprising:
a visible light transmissive member that transmits visible light and reflects infrared light;
a wearing member that is worn by a wearer and holds the visible light transmissive member so as to be disposed in front of eyes of the wearer;
a sensor that detects infrared light emitted from the wearer and reflected by the visible light transmissive member; and
a processor that estimates a body temperature of the wearer on a basis of the infrared light detected by the sensor.
2 . The body temperature estimating device according to claim 1 , wherein
the visible light transmissive member is an eyeglass lens, and
the wearing member is an eyeglass frame.
3 . The body temperature estimating device according to claim 2 , wherein
the sensor is disposed on a temple of the eyeglass frame.
4 . The body temperature estimating device according to claim 1 , wherein
the visible light transmissive member is a shield that covers at least a part of a face of the wearer, and
the wearing member is a frame worn on a head of the wearer.
5 . The body temperature estimating device according to claim 4 , wherein
the sensor is disposed on the frame.
6 . The body temperature estimating device according to claim 1 , wherein
the visible light transmissive member is subjected to dielectric multilayer film coating.
7 . A body temperature estimating method comprising:
detecting infrared light emitted from a wearer wearing a wearing member, the wearing member holding a visible light transmissive member, that transmits visible light, so as to be disposed in front of eyes of the wearer, and reflected by the visible light transmissive member; and
estimating a body temperature of the wearer.
