Abstract

The present application discloses an infrared temperature measurement method, device, equipment, and storage medium. The method includes: obtaining the actual temperature measured by the infrared imaging system for the target; according to the environmental variables and the normalized spectral response function of the infrared imaging system, Atmospheric attenuation correction is performed on the obtained temperature to obtain the first temperature data; the functional relationship between the output energy of the central point of the infrared imaging system and the imaging radius of the target is established to obtain the target proportion correction function; according to the acquired target proportion function and the target The imaging radius of the first temperature data is corrected for the target imaging ratio to obtain the second temperature data. Through this method, the complexity of the traditional single-band calibration temperature measurement scheme can be solved, and at the same time, the accuracy of temperature measurement for medium and long-distance targets can be improved, and timely monitoring of high-temperature targets can be achieved, and preventive temperature measurement such as forest fire prevention and fire early warning can be realized. Check function.

Description

technical field [0001] The invention relates to the technical field of infrared temperature measurement, in particular to an infrared temperature measurement method, device, equipment and storage medium. Background technique [0002] Infrared imaging temperature measurement technology has a wide range of applications in infrared detection, infrared remote sensing, military target measurement, industrial monitoring, forest fire prevention and other fields. Due to the complex principle of infrared temperature measurement, there are a large number of factors that affect the accuracy of temperature measurement (including lens parameters, environmental variables, distance coefficients, target emissivity, output drift of the infrared detector itself, etc.), especially in the field of long-distance temperature measurement. , it has been difficult to have a better temperature measurement application scheme and algorithm. [0003] At present, for infrared imaging systems, the tradit...
