Infrared temperature measurement thermal imaging device and real-time calibration temperature measurement method thereof

The invention discloses an infrared temperature measurement thermal imaging device and a real-time calibration temperature measurement method thereof. The infrared temperature measurement thermal imaging device comprises a reference constant temperature unit with fixed emissivity, an optical lens, an infrared radiation receiving unit and an information processing unit. The optical lens transmits infrared radiation emitted by the measured target and the reference constant temperature unit to the infrared radiation receiving unit at the rear part. The infrared radiation receiving unit processesthe infrared radiation into an analog signal. The information processing unit processes the received analog signal into a digital signal to obtain a noise reduction digital signal value, and outputs atemperature value corresponding to the measured target according to a pre-established mapping relationship between the noise reduction digital signal value and the temperature value. Therefore, the structure of the infrared t
