Description of the invention: [Technical field to which the invention belongs] In particular, it refers to a fever screening method using a screening method such as image processing technology combined with infrared temperature measurement technology [previous technology] There are many types of thermometers. It roughly includes: mercury type, electronic type, ear thermometer and forehead thermometer, and even infrared thermal imager. Different types of i 10 and 15 have different measurement methods and recognition degrees. Mercury type and = type thermometers are contact thermometers. When using it, you must be in close contact with the human body to measure the correct body temperature. The measurement sites mainly include anal temperature, abdominal temperature, and mouth temperature. The direct contact measurement temperature is more accurate, but the response of the sensing element takes a long time and cannot be used as Fast fever screening station use. Ear thermometers and forehead thermometers or infrared thermographs are non-connected measurements, mainly using infrared sensors to sense the body surface temperature. The measurement time is short, but the body surface temperature varies with the air environment. Changes, so the measured value should be corrected. Although the ear thermometer is more accurate, it takes time to change the earmuffs and read the temperature, and the potential danger of close contact is eliminated. 'Earphone consumables are also a waste, and the helmet method is susceptible to fork infection. In some large places, some advanced places have started to use more advanced infrared imaging cameras to measure body temperature in order to facilitate the screening of fever. However, the cost of infrared imaging cameras has been increasing. Million,. ^ ^ Day 1 ^ $ 目 田 叩 贞 'When measuring body temperature with an infrared meter, because the temperature of the entire image is observed, not only the surface temperature of the human skin, so' when the subject When entering the room from outside 20 1240070, hair, masks, and even dark clothes absorb more heat due to sunlight, and also emit more heat indoors, resulting in the subject being dissipated by other non-human body heat dissipation problems. The instrument was misjudged as a fever, and you need to cooperate with someone to monitor the fever position. [Summary of the Invention] 15 Therefore, an object of the present invention is to provide a fever screening method that is low in cost and can reduce misjudgement of fever. Therefore, a method for screening for fever according to the present invention includes: a) detecting a subject to generate a start-up instruction; transmitting the start-up instruction to a central processing unit and starting an image unit to capture the results The subject's image, c) processing the aforementioned image to generate a tracking instruction; d) sending the tracking instruction to a turn around a few days earlier so that an infrared temperature detection turns the tracked subject early; -The primary measurement unit detects the distance between the subject and the infrared temperature detection and generates a measurement instruction; and f) transmits the measurement instruction to the body temperature of the infrared temperature detection unit.
