Abstract

The invention relates to a high-precision infrared thermal-imaging temperature measurement method and a high-precision infrared thermal-imaging temperature measurement system. The method includes: acquiring a gray image of a detected area by an infrared focal plane array and an optical mechanism; acquiring a temperature of a reference object and a gray value of a reference object gray image area in the gray image; acquiring a gray value of a to-be-measured object gray image area in the gray image to acquire a first temperature of a to-be-measured object; subtracting the gray value of the to-be-measured object from the gray value of the reference object to obtain a gray difference, and obtaining a temperature difference according to the gray difference and the change relationship between the first temperature and the image gray value; obtaining the temperature of the to-be-measured object by the temperature of the reference object and the temperature difference. The high-precision infrared thermal-imaging temperature measurement method and the high-precision infrared thermal-imaging temperature measurement system achieve high-precision infrared thermal-imaging temperature measurement based on the detector operating temperature and a relative measurement method, thereby being high in temperature measurement precision, small in temperature measurement precision fluctuation and high in stability.

Description

Technical field [0001] The invention relates to an infrared thermal image temperature measurement method and system, in particular to a high-precision infrared thermal image temperature measurement method and system based on the working temperature and relative measurement of a detector. Background technique [0002] With the development of electronic technology, infrared imaging and infrared temperature measurement are more and more widely used in many areas of people's production and life. The existing infrared thermal imaging temperature measurement technology is affected by the temperature change of the infrared thermal imaging device itself and the optical mechanism, resulting in low temperature measurement accuracy, large temperature measurement accuracy fluctuations, and poor stability. Especially when high-precision temperature measurement is performed on the human body, the temperature measurement accuracy often cannot meet the requirements of use, resulting in false ala...
