Problems solved by technology

In addition, using "calibration coefficient" or univariate empirical formula to correct long-distance attenuation has low applicability for applications under different ambient temperatures and different lenses, and the calibration is complicated. For forest fire prevention, fire warning, etc., wide field of view / far There has been no better application solution for distance temperature measurement requirements

Abstract

The invention discloses an infrared temperature measurement method, device and equipment, and a storage medium. The method comprises the steps of acquiring a temperature actually tested by an infraredimaging system for a target; according to the environmental variable and a normalized spectral response function of the infrared imaging system, carrying out atmospheric attenuation correction on theacquired temperature to obtain first temperature data; establishing a function relationship between the output energy of the central point of the infrared imaging system and the imaging radius of thetarget, and obtaining a target proportion correction function; and according to the obtained target proportion function and the imaging radius of the target, performing target imaging proportion correction on the first temperature data to obtain second temperature data. By means of the method, the complexity of a traditional single-waveband calibration temperature measurement scheme can be solved, meanwhile, the temperature measurement accuracy of middle and long distance targets is improved, a high-temperature target can be monitored in time, and preventive temperature measurement and inspection functions such as forest fire prevention and fire early warning are achieved.

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 is widely used in infrared detection, infrared remote sensing, military target measurement, industrial monitoring, forest fire prevention and other fields. Due to the complexity of the 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.), resulting in , it has been difficult to have a better temperature measurement application scheme and algorithm. [0003] At present, for infrared imaging systems, the traditional single-band calibration temperature measurement scheme ...
