Description

technical field [0001] The invention relates to the field of computer technology, in particular to a long-distance human face temperature measurement system based on infrared imaging, an implementation method, computer equipment and a storage medium. Background technique [0002] Temperature measurement on the human body surface is one of the main means to deal with epidemic infectious diseases at present. However, in the existing technology, the traditional non-contact temperature measurement of the human body is mostly carried out by hand-held infrared temperature measuring instruments, the temperature measurement distance is controlled within 3-5cm, each measurement takes 3-5 seconds, and can only People carry out, and the detection efficiency is low. In addition, considering the cost factor, single-point temperature measurement is often used, and the accuracy of the temperature measurement results cannot be well guaranteed. Therefore, in response to emergencies, tradit...

However, in the existing technology, the traditional non-contact temperature measurement of the human body is mostly carried out by hand-held infrared temperature measuring instruments, the temperature measurement distance is controlled within 3-5cm, each measurement takes 3-5 seconds, and can only People conduct, detection efficiency is low

In addition, considering the cost factor, single-point temperature measurement is often used, and the accuracy of the temperature measurement results cannot be well guaranteed.

Therefore, in response to emergencies, traditional temperature measurement methods cannot achieve large-scale, rapid, long-distance and high-precision human body temperature measurement
