Correction method for infrared-measurement human body temperature

Abstract

The invention relates to a correction method for the infrared-measurement human body temperature. The method comprises the steps that a limited area of basic crowd temperature collection is automatically learned, based on visitor human face temperature data collected in the limited area, the visitor human face temperature data is analyzed, whether or not the working time of one day needs to be divided into different time periods is judged, and if yes, the basic crowd temperatures in different time periods are calculated; one time period with the highest basic crowd temperature is determined, human face temperature data in other time periods is adjusted, so that the basic crowd temperatures in other time periods are identical to that in the time period with the highest temperature, after the human face temperature data is adjusted, all human face temperature data is sorted, and a main temperature distribution range and a temperature alarm value are calculated; according to the obtainedmain temperature distribution range and temperature alarm value, the collected temperature is corrected. The method adapts to body temperature change of the human body in the morning, afternoon and evening of one day under different regional climates and weather changes; the degree of dependence on experience of workers is lowered.

Description

technical field [0001] The invention relates to the field of infrared temperature measurement, in particular to a correction method for infrared measurement of human body temperature. Background technique [0002] The existing technology does not consider the influence of environmental factors such as temperature and humidity caused by regional climate and seasonal changes on the body surface temperature of the human body, and uniformly uses the same body surface temperature to compensate the same temperature value for temperature correction. The operator needs to adjust the size of the compensation parameters according to the actual situation, which requires a high level of experience for the staff. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a correction method for infrared measurement of human body temperature, which can adapt to different regional climates, weather changes, body temperature changes i...
