Problems solved by technology

[0002] Body temperature measurement is a commonly used inspection method for clinical disease prevention and diagnosis. Currently, commonly used body temperature measurement technologies mainly include using thermometers to measure body temperature and infrared face temperature measurement. Traditional mercury thermometers require a long time to measure body temperature, and electronic thermometers also require close proximity. The body temperature can only be measured close to each target object, which is not suitable for epidemic prevention and control in public places; while the existing medium and long-distance infrared face temperature measurement technology, the general temperature measurement distance is 1 to 5 meters, which can be used in public places. Non-cooperative face temperature measurement in places, but due to its complex application environment and low degree of personnel cooperation, the body temperature accuracy measured by the existing infrared face temperature measurement technology is often affected by various occlusions of the face, so that in practice The temperature measurement accuracy in the application scenario has a large fluctuation
Therefore, the existing infrared face temperature measurement technology still has the problem of low temperature measurement accuracy.
