Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a non-contact type body temperature measuring apparatus for measuring body temperature information using a thermal image sensor,

The present invention relates to a technical idea for measuring body temperature information using a thermal image sensor, and more particularly, to a non-contact type body temperature measuring apparatus for analyzing a thermal image acquired through a thermal image sensor and measuring body temperature information of the measurement object, And to a method of operation.

Generally, a clinical thermometer can be classified into a contact type thermometer and a non-contact type thermometer.

In order to measure the body temperature, the contact type thermometer can directly measure the body temperature of the person to be measured by using the thermal conduction of the body temperature.

On the other hand, the non-contact type thermometer can measure the body temperature of the person to be measured by measuring infrared rays emitted from the body of the person to be measured.

The contact type thermometer should be contacted to the anal or underarm of the person to be measured and the body temperature of the person to be measured should be measured. However, the contact-type thermometer may cause problems such as inconvenience that continuous contact is required to the measurement target site for a predetermined time, and infection due to contact.

On the other hand, the non-contact type thermometer measures the body temperature of the measurement subject by measuring infrared rays emitted from the temporal artery of the eardrum or forehead of the measurement subject.

Non-contact thermometers have the advantages of shorter measurement times compared to contact thermometers, but in the case of measurements through the eardrum, body temperature can be measured incorrectly depending on the shape of the ear or ear canal. In addition, there is a disadvantage that the non-contact type thermometer must accurately determine the temporal artery in the measurement through the temporal artery.

In addition, the contact type thermometer and the non-contact type thermometer can measure the body temperature only when the measurer intends to measure the body temperature of the person to be measured.

Therefore, the contact type thermometer and the non-contact type thermometer have a disadvantage in that it is impossible to continuously measure the body temperature of the measurement subject and can not perform functions such as predicting the disease or checking the health state using the thermo-mechanical bio-signal data.

Therefore, a body temperature measuring device which is hygienic and can relieve inconvenience of the measurement subject and can perform disease prediction or health condition check based on continuous measurement is developed by complementing the disadvantages of the contact type thermometer and the non-contact type thermometer according to the prior art There is a need to be.
