Infrared camera calibration can be performed by the operator using common household items.

Infrared camera calibration can be performed by the operator using common household items.

• A. Yes
• B. No
• C. Only with official manuals
• D. Only when brand new

Answer: (B)

Calibration of an infrared camera is a precise radiometric process that ties pixel values to actual temperatures using known, stable references. You need a calibrated temperature source, like a blackbody radiator or certified targets with known emissivity, and controlled conditions (temperature, distance, ambient reflections) to create an accurate mapping from radiance to temperature. Common household items don’t provide a reliable, traceable temperature reference; their emissivity varies widely, their temperatures aren’t known or stable, and they reflect heat from the surroundings. Using them would introduce unpredictable errors and undermine the camera’s accuracy. You can still perform basic visual checks or rough assessments with familiar objects, but proper calibration requires appropriate calibration equipment and following the manufacturer’s procedures.
