Infrared human body temperature measurement correction method

Abstract

The invention discloses an infrared human body temperature measurement correction method. The method comprises the steps of automatically detecting the environment temperature, dividing the external environment temperature into N intervals, and repeatedly testing the surface temperature of the human body in each interval, verifying the real surface temperature by using a calibration black body, and finding out the relationship between the environment temperature and the surface temperature of the human body, so that the body surface temperature measured at each environment temperature is corrected into a real temperature value to reduce the influence of the environment temperature on the surface temperature of the human body. The method can be suitable for influences of external temperature changes in different regions, different seasons and different weathers on the body temperature of the human body, dependence on experience of workers is reduced, rapid screening of heating groups isfacilitated, and the application environment range is wider.

Description

technical field [0001] The invention relates to the technical field of infrared human body temperature measurement, in particular to an infrared human body temperature measurement correction method. Background technique [0002] In recent years, various epidemic viruses have emerged one after another, and how to prevent and control the spread of these diseases has become a common issue discussed by the whole world. Now the outbreak of the new coronavirus requires us to do a good job in prevention and control. These types of viruses all have a common feature, that is, most of them have symptoms such as body temperature, fever and high fever during the onset, so temperature measurement of mobile populations is particularly important. Especially some public places with a large flow of people, such as stations, docks, schools, office halls, factories, large supermarkets, etc., require a large number of body temperature tests. At present, the method of measuring forehead temper...

AI Technical Summary

Problems solved by technology

At present, the method of measuring forehead temperature with infrared thermometer is relatively popular, but there are disadvantages such as slow detection speed, close distance between staff and testing personnel, easy to cause cross-infection, and high protection requirements for staff.

The infrared thermal imaging sensor can realize fast non-contact human body temperature detection, and correct the temperature of the base layer of the body, but the temperature environment of the base layer of the body is somewhat different from the actual temperature environment, resulting in a certain error in the measurement results
