Correction apparatus, correction system, correction method, and non-transitory computer-readable medium

A correction method implemented by a computer, comprising:

• acquiring a body surface temperature of a first person who has stayed outdoors for a predetermined time or longer from a video image captured by a thermal camera and calculating, on the basis of a result of measurement of a body temperature of the first person, a correction value to be used for correcting a body surface temperature;
• and
• acquiring a body surface temperature of a second person different from the first person from a video image captured by the thermal camera and correcting a body surface temperature of the second person on the basis of the correction value,
• wherein the correction method further comprises:
• generating a correction table showing a correspondence relationship between a correction value for the body surface temperature of the first person and attributes of the first person.

A non-transitory computer-readable medium storing a correction program for causing a computer to further perform processing of:

• acquiring a body surface temperature of a first person who has stayed outdoors for a predetermined time or longer from a video image captured by a thermal camera and calculating, on the basis of a result of measurement of a body temperature of the first person, a correction value to be used for correcting a body surface temperature;
• and
• acquiring a body surface temperature of a second person different from the first person from a video image captured by the thermal camera and correcting a body surface temperature of the second person on the basis of the correction value,
• wherein the correction program causes a computer to further perform processing of:
• generating a correction table showing a correspondence relationship between a correction value for the body surface temperature of the first person and attributes of the first person.
