Temperature calibration method for a temperature measuring device

A temperature calibration method, comprising:

• providing a temperature measuring device, wherein the temperature measuring device includes a first non-contacting temperature sensing module having a first temperature-measuring viewing angle, and a second non-contacting temperature sensing module having a second temperature-measuring viewing angle;
• measuring a predetermined heating temperature that is generated by a black substance by the second non-contacting temperature sensing module at the second temperature-measuring viewing angle so as to obtain black body temperature information of the black substance;
• and
• calibrating the first non-contacting temperature sensing module according to the black body temperature information that is obtained by the second non-contacting temperature sensing module.

A temperature calibration method, comprising:

• providing a temperature measuring device, wherein the temperature measuring device includes a movable shutter module, and a first non-contacting temperature sensing module having a first temperature-measuring viewing angle, the movable shutter module includes an electric control driver, a movable shutter structure connected to the electric control driver, and an electric control heater disposed on the movable shutter structure, and the movable shutter structure includes a black substance for generating a predetermined heating temperature from being heated by the electric control heater;
• moving the movable shutter structure to a first position by driving of the electric control driver, so as to completely block the first temperature-measuring viewing angle of the first non-contacting temperature sensing module by the black substance of the movable shutter structure;
• measuring the predetermined heating temperature that is generated by the black substance of the movable shutter structure by the first non-contacting temperature sensing module at the first temperature-measuring viewing angle so as to obtain black body temperature information of the black substance;
• and
• calibrating the first non-contacting temperature sensing module according to the black body temperature information that is obtained by the first non-contacting temperature sensing module.
