Infrared temperature measurement method, device and equipment

Abstract

The invention discloses an infrared temperature measurement method. The method comprises the steps of acquiring a first gray scale parameter, a second gray scale parameter and a target gray scale parameter; acquiring a first temperature parameter and a second temperature parameter; utilizing the first gray scale parameter, the second gray scale parameter, the first temperature parameter and the second temperature parameter to obtain responsivity of an infrared sensor; obtaining a relative temperature difference value through the responsivity, the first gray scale parameter and the target grayscale parameter; and obtaining a to-be-measured target temperature value through the relative temperature difference value and the first temperature parameter. The method is advantaged in that by obtaining the temperature values of the two constant-temperature reference assemblies and an output gray value of the infrared rays, a problem that long-time waiting needs to be carried out after startuptill the system temperature is stable and heat balance with the external environment is achieved is avoided, and rapid and accurate infrared temperature measurement at different environment temperatures is achieved. The invention further provides an infrared temperature measuring device and equipment with the advantages.

Description

technical field [0001] The invention relates to the field of infrared temperature measurement, in particular to an infrared temperature measurement method, device and equipment. Background technique [0002] Any object with a temperature above absolute zero (-273.15°C) is constantly emitting infrared radiation (thermal radiation). Infrared radiation is a kind of electromagnetic wave with a wavelength range of 0.7 μm to 1000 μm, which is invisible to the human eye, and the wavelength of external radiation is different at different temperatures. After the infrared temperature measurement thermal imaging system captures infrared radiation, it converts it into an electrical signal, which is processed by an algorithm and finally outputs temperature information. Calculate according to the corresponding changes to obtain the corresponding temperature information. [0003] However, due to the fact that the infrared temperature measurement and thermal imaging system is easily affec...
