An infrared temperature measurement method, device and equipment

Abstract

The invention discloses an infrared temperature measurement method, by obtaining the first grayscale parameter, the second grayscale parameter and the target grayscale parameter; obtaining the first temperature parameter and the second temperature parameter; using the first grayscale parameter, The second grayscale parameter, the first temperature parameter, and the second temperature parameter obtain the response rate of the infrared sensor; through the response rate, the first grayscale parameter, and the target grayscale parameter, A relative temperature difference is obtained; the target temperature value to be measured is obtained through the relative temperature difference and the first temperature parameter. By obtaining the temperature value of two constant temperature reference components and the output gray value of infrared rays, the present invention avoids the problem of waiting for a long time after starting up until the system temperature is stable and achieves thermal equilibrium with the external environment, and realizes fast and accurate detection under different ambient temperatures Infrared temperature measurement. The present invention also provides an infrared temperature measuring device and equipment with the above-mentioned 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...
