IR-based Detection of Elevated Body Temperature for Coronavirus, SARS, Ebola

Use Infrared Cameras to Identify Elevated Body Temperature

Major travel hubs like airports, seaports, railway stations and long-distance bus stations are one of the points on which the security measures of public authorities are aimed when infectious diseases such as

  • Coronavirus (2019-nCoV, COVID-19, SARS-CoV-2)
  • Severe Acute Respiratory Syndrome (SARS)
  • Ebola Virus Disease (EVD)
  • Middle East Respiratory Syndrome Coronavirus (MERS-CoV)

cause global problems. From there, diseases can be effectively prevented from spreading further.

InfraTec infrared cameras can be used for a corresponding scanning of elevated body temperature for passengers. Certainly, thermographic cameras can neither detect the virus itself nor a person carrying the virus! However, these cameras enable the precise non-reactive, contactless and planar recording of surface temperatures while using the technical temperature measurement technology known as thermography. Hence, they are highly suitable for the quick and easy detection of elevated body temperatures, which can be an indication of a possible virus infection of people subjected to screening.

The body temperature preferably is detected at the inner angle of the eye with the infrared camera. Slightest differences and thus abnormal body temperatures can be displayed and will result in alarms. Performing such health screenings, e.g. via implementing temperature checkpoints, enable the acquisition of important information as a basis for decision-making for subsequent medical examinations of the selected people and thus serve to secure public areas.

Such indications must, of course, always be followed by other examination methods that allow a reliable positive or negative statement about the disease and to initiate appropriate actions!

Infrared Cameras are not medical diagnostic instruments for fever detection but technical measuring devices for scanning of people

The term "detecting a fever" in the sense of a (medical) fever diagnosis is actually not permitted as a designation for the above-mentioned thermographic recording of elevated body temperatures with thermal cameras under strict observation: One reason is that fever is a complex medical phenomenon. The other reason is that, from a purely formal point of view, the cameras used are "only" technical measuring devices and not medical diagnostic instruments.

Achieve Reliable Measurement Results for Detection of Elevated Body Temperature

The thermographic temperature measurement for detection of elevated body temperature puts high demands on suitable thermal cameras: In addition to a high thermal resolution, which can make even the smallest temperature differences visible, there must be very good stability and measuring accuracy in order to be able to reliably distinguish a person with an elevated body temperature from a person without these symptoms using critical temperature thresholds and alarm values.

Another very important criterion is the required high geometric resolution, which is expressed in the number of so-called infrared (IR) pixels. This is necessary because the area that has been proven in several studies to be suitable for reliably detecting elevated body temperature at the inner eyelid angle has only a small surface area, but must be sharply mapped for error-free temperature measurement.

The measurement itself takes less than a second and is usually carried out in access areas, for example at the entry control at airports, where the people who are to be screened are already lined up. Largely determined by the wide-ranging requirements of the users, the evaluation of the measured data can range from simple manual use to select people with elevated body temperature for further examinations to automatic detection and storage.

Comfortable Software Package THERMAL-CHECK

Besides the infrared camera, application-specific software also plays an important role. The THERMAL-CHECK software of InfraTec offers all the functionality needed for the detection of elevated body temperature in various scenarios and is still intuitively usable. It reliably determines the small area of the human face where reliable body temperature determination is possible.

  • Automatic optical and optionally acoustic alarm
  • Algorithm-based measurement accuracy of to ± 0.3 K
  • Convenient camera remote control
  • Individual configurations of alarms and external information displays or monitors
  • “Anonymous mode“ selectable for data protection
