Abstract

The invention discloses an infrared thermal imager device, which comprises an infrared lens, a lens bracket and an infrared detector chip, and is characterized in that the infrared lens sleeves the front end of the lens bracket, and a frame body at the rear end of the lens bracket covers the infrared detector chip; a diaphragm blade in the middle of the infrared lens or a non-light-transmission area of a lens support is coated with a black high-emissivity material, and the requirement that the infrared imaging height of the infrared lens shielded by the black high-emissivity material is smaller than 1/2 of the diagonal length of an infrared detector chip is met;and the part shielded by the black high-emissivity material is imaged on the dark corner of the infrared detector chip. The infrared thermal imager device is simple in structure, small in size and capable of achieving real-time temperature adjustment, the temperature real-time correction method is easy and convenient to operate and high in operability, and the temperature of the thermal infrared imager can be adjusted in real time.

Description

technical field [0001] The invention relates to the field of infrared detection, in particular to an infrared thermal imager device and a temperature real-time calibration method thereof. Background technique [0002] At present, the current infrared imager is calibrated with an external blackbody radiation source or temperature sensor. The space and time difference between the calibration position and frequency and the actual person or object leads to a large cumulative temperature error; and real-time calibration can accurately obtain the measured temperature. The actual temperature of the person or object. [0003] In the prior art, there is a real-time calibration device for an infrared thermal imager, which includes an infrared thermal imager, a temperature sensor, a calibration panel, a sensor data line and an embedded module; The embedded module, the embedded module and the temperature sensor are respectively supported and set in the working environment through brack...
