ERROR CORRECTION UNIT AND OBJECT TEMPERATURE DETECTION DEVICE
Disclosed is an error correction unit enabling constant accurate measurement of a moving object by correcting an error attributable to a change in sensitivity of a thermal image sensor, a change in distance between a thermal image sensor and an object, or an ambient environment. Further disclosed is an object temperature detection device equipped with the same. The error correction unit includes a first arm member rotatably coupled to a thermal imaging camera unit, a heating element holder rotatably coupled to the first arm member, the heating element fixed to the heating element holder, and a temperature sensor configured to measure a temperature of the heating element. The heating element is positioned within an angle of view of the thermal imaging camera unit through rotational motion of the first arm member and the heating element holder.
