An accurate temperature measurement structure of a wide temperature range includes: a lens set; an optical base, having a neutral density slot and being fixed with the lens set by a first screw; a mask shutter assembly, fixed with the optical base by a second screw; and a temperature sensing unit, for sensing a target object temperature so as to obtain a measured temperature value, the temperature sensing unit performing a temperature normalization correction when the accurate temperature measurement structure of the wide temperature range is in a power-on stage to obtain a signal strength value, setting a plurality of signal conditions according to the signal strength value to obtain a dynamic linearity strength value and accordingly determining an extreme value region, so as to determine whether to add a neutral density filter to the neutral density slot.

Accurate temperature measurement structure of wide temperature range and method thereof

A temperature measurement calibration method without interference of a shutter of a thermal imaging module comprises steps: at a temperature of a core chip of a thermal imaging module, obtaining a response value generated by measuring a blackbody temperature after the shutter is started at a frame time; performing a linear regression analysis of the response value to obtain a correction response value equation; inputting the response value into the correction response value equation; and obtaining a correction response value of measuring the blackbody temperature.
