Claims17
A face recognition body temperature measuring apparatus comprising:
- a communication module configured to receive a video image and a thermal image obtained by simultaneously imaging at least one target object from a camera module;
- a memory configured to store a body temperature measurement program for measuring a body temperature by using the video image and the thermal image;
- and
- a processor configured to execute the body temperature measurement program stored in the memory,
- wherein the processor sets a face area by detecting a face of the target object in the video image, sets, in the thermal image, a temperature measurement area corresponding to the face area in the video image, calculates a greatest infrared intensity value which is a greatest value of infrared intensity values in the temperature measurement area, calculates an infrared intensity value of a temperature measurement target by adding, to the greatest infrared intensity value, a first correction value calculated based on infrared intensity values of a specific object that varies according to a measurement distance, a second correction value calculated based on infrared intensity values of a specific object that varies according to an external temperature, and a third correction value calculated based on infrared intensity values of a specific object that varies according to a change rate of the external temperature, and calculates a body temperature of the at least target object by using a difference between the infrared intensity value of the temperature measurement target and an infrared reference value preset by the face recognition body temperature measuring apparatus.
