Title:
DEVICE FOR IMPROVING TEMPERATURE ACCURACY OF THERMAL IMAGING CAMERA FOR DETECTING HUMAN BODY
Document Type and Number:
WIPO Patent Application WO/2022/005121
Kind Code:
A1
Abstract:
The present invention relates to a device for improving the temperature accuracy of a thermal imaging camera for detecting a human body, and provides a device for improving the temperature accuracy of a thermal imaging camera for detecting a human body, the device being capable of obtaining an accurate temperature value of a subject by converting the temperature value by using a deviation between a temperature data value of the subject, which is emitted from the subject and input to a temperature controller via a thermal image sensor, and a temperature data value input to the temperature controller via the thermal image sensor from a temperature adjusting device that is set to an arbitrary temperature within a human body temperature range. The technical configuration of the device for improving the temperature accuracy comprises: the thermal image sensor which detects an infrared ray image emitted from the subject and input through a lens, and then outputs the infrared ray image as an electrical signal; a temperature adjusting unit which is arranged on one side of the front surface of the lens and generates heat to a set temperature within the human body temperature range; and the temperature controller which measures the current temperature by using a deviation between the temperature data value of the subject input to the thermal image sensor and the set temperature data value of the temperature controller input to the thermal image sensor.
