Title:
INFRARED TEMPERATURE MEASUREMENT METHOD, APPARATUS, DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/110283
Kind Code:
A1
Abstract:
Provided are an infrared temperature measurement method, apparatus, device, and storage medium: acquiring a temperature actually measured by an infrared imaging system in respect of a target; according to environment variables and a normalized spectral response function of the infrared imaging system, performing atmospheric attenuation correction on the acquired temperature to obtain first temperature data; establishing a functional relationship between an output energy at the center of the infrared imaging system and the imaging radius of the target to obtain a target proportion correction function; 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, it is possible to resolve the complexity of a conventional single-band calibrated temperature measurement solution, while also improving the accuracy of temperature measurement of medium- and long-range targets, and to achieve timely monitoring of high-temperature targets and perform forest fire prevention, fire warning, and other preventive temperature measurement and testing functions.
