Abstract: A temperature calibration method of an infrared thermal image camera and a calibration method of a temperature sensing system of an infrared thermal image camera are provided. The temperature calibration method of the infrared thermal image camera includes: providing a temperature sensing system to measure an object under test, so as to obtain an uncalibrated temperature; and calibrating the uncalibrated temperature to obtain a calibrated temperature, according to the uncalibrated temperature and a temperature calibration function. The temperature calibration function is obtained through a regression analysis.
