Only the Temperature Reading from the Inner Corner of the Eye (Periorbital Area) Is Meaningful as a Reference<\/span><\/strong>
Since the outbreak of COVID-19 in early 2020, temperature screening has become an important first line of checks, using devices such as handheld forehead thermometers, ear thermometers, and infrared temperature sensors. According to ISO\/TR 13154:2017, the most reliable place to measure human body temperature is actually the \u201cinner canthus\u201d (inner corner of the eye) region, because this area sits above the carotid artery, making its temperature more stable and reliable than other areas of the body. Other areas can show elevated or reduced surface temperature due to sweating or other external environmental factors. \u200bBelow is an actual measurement taken with a thermal camera. The left image shows a person with a normal body temperature, with the thermal camera reading 36.5\u00b0C, while the right image shows a person with a fever, where the temperature around the eye socket is clearly higher than the surrounding areas. <\/span><\/span><\/p>

To make temperature measurement more accurate, it's also important to avoid \u201ccovering the measurement area\u201d
Anyone who has traveled abroad knows that automated border control requires removing glasses, hats, and other coverings to ensure accurate recognition. The same applies to temperature detection, since these items interfere with measurement accuracy. Below are test results from a thermal camera showing how various coverings affect thermal temperature readings.<\/span><\/p>

(Figure 1) Wearing sunglasses, the eye area is almost completely covered.
(Figure 2) When wearing a mask, the warmth from exhaled breath is reflected back onto the face, causing the detected reading to be higher.
(Figure 3) A hat covering the head prevents the eye area from being measured.<\/span><\/p>

In response to the global pandemic, traditional thermal cameras have also jumped on the smart video recognition trend, adding features like mask detection and facial recognition. While pairing these features with thermal imaging can speed up recognition and reduce the influence of other hot objects in the environment, the detected temperature is still only a reference. The equipment is just an aid \u2014 it's recommended that on-site staff still perform a secondary, more precise measurement based on the initial reading, to be absolutely sure.<\/span><\/h3>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t
