Abstract

A calibration method, device for infrared temperature measurement, an electronic apparatus and a storage medium are provided. The method includes: obtaining a monitoring temperature and an actual temperature of a black body, wherein the monitoring temperature of the black body is monitored by an infrared thermal imager, and the black body is an object having a thermal conductivity greater than a first threshold and being uniformly heated; calculating a difference between the monitoring temperature and the actual temperature; and calibrating the infrared thermal imager with the difference. In the embodiment of the present application, the cost of the black body is reduced and the stability of a measurement result is improved, thereby improving using effect of the calibration method for the infrared temperature measurement.

Claims (13)

1. A calibration method for infrared temperature measurement, comprising:

obtaining a monitoring temperature and an actual temperature of a black body, wherein the monitoring temperature of the black body is monitored by an infrared thermal imager, and the black body has a thermal conductivity greater than a first threshold and is uniformly heated, wherein a material of the black body comprises a metal;

calculating a difference between the monitoring temperature and the actual temperature; and

calibrating the infrared thermal imager with the difference; wherein the difference is used for real-time compensation for the monitoring temperature of an object/a human body to ensure data of the monitoring temperature of the object/the human body obtained each time is calibrated with reference to data of the black body.

2. The calibration method according to claim 1 , wherein a surface of the black body is an object having an emissivity greater than a second threshold and a thermal conductivity coefficient greater than a third threshold.

3. The calibration method according to claim 1 , wherein the metal comprises aluminum or red copper.

4. The calibration method according to claim 2 , wherein the metal comprises aluminum or red copper.

5. The calibration method according to claim 1 , wherein a surface of the black body comprises a graphene coating or an adhesive tape.

6. The calibration method according to claim 2 , wherein a surface of the black body comprises a graphene coating or an adhesive tape.

7. The calibration method according to claim 1 , wherein the actual temperature of the black body is measured by a temperature sensor provided into the black body.

8. The calibration method according to claim 2 , wherein the actual temperature of the black body is measured by a temperature sensor provided into the black body.

9. The calibration method according to claim 1 , wherein the black body is heated by a constant voltage power supply and a heating wire.

10. A non-transitory computer-readable storage medium, in which instructions of a computer are stored, wherein the instructions are configured to enable the computer to implement the method according to claim 1 .
