Externally mounted temperature calibration device for thermal imaging cameras and temperature measurement system using it

摘要

The present invention corrects the temperature of a thermal imaging camera by using an externally mounted temperature calibration device including a temperature measuring substrate having a temperature sensor, wherein the temperature measuring substrate of the externally mounted temperature calibrating device is displayed on the screen of the thermal imaging camera. The temperature of the measurement target measured by the thermal imaging camera is measured using the temperature of the temperature measurement substrate measured by the temperature sensor and the temperature measurement substrate measured by the thermal imaging camera. It relates to an externally mounted temperature calibrator and a temperature measurement system using the same, capable of maintaining a constant temperature measurement result regardless of the environmental temperature in which the thermal imaging camera is used by correcting it. The present invention is provided with a thermal imaging camera for measuring the temperature of the target object, the thermal imaging camera unit; An externally mounted temperature calibrating device located outside the thermal imaging camera unit, including a temperature measuring substrate configured to be photographed together with the thermal imaging camera, the externally mounted temperature calibrating device is configured to include a heat It is characterized in that it is fixed and mounted on one side of the image camera unit. A temperature sensor is mounted on the surface facing the thermal imaging camera and the opposite side of the substrate for temperature measurement. For temperature measurement by the thermal imaging camera, from the image of the temperature measurement substrate photographed together when the target is photographed. The calculation processing unit detects the temperature of the substrate, and using the difference between the temperature of the substrate for temperature measurement by the thermal imaging camera and the temperature of the substrate for temperature measurement detected by the temperature sensor, the measurement target photographed by the thermal imaging camera The calculation processing unit corrects the thermal image including the object.
