Thermal Imaging for Detecting Elevated Body Temperature

The world has become a lot smaller and much more accessible. This was possible due to transportation technologies such as aviation, which are becoming more affordable. With new airline routes becoming more accessible, people now travel the world frequently. However, this can pose risks to countries, and their people as travelers can introduce new illnesses and viruses into other countries. 

 

Considering the present day scenario of COVID-19, this situation has become more serious. Such viruses cause a high body temperature or, sometimes, an indicator of serious illnesses such as SARS, Ebola, and recent COVID-19.

Thermal temperature detection can often be set up at border crossings such as airports, seaports, and public areas to prevent the spread of such lethal-contagious diseases.

 

What is Thermal Imaging?

 

It is a process that creates an image using Infrared Radiation. Every living emits some form of Infrared Radiation, including humans and animals. Infrared radiation is directly affected by temperature—the higher the temperature, the more Infrared is issued, and vice-versa. In a thermal camera, a microbolometer as the detector generates a thermal image by applying a color palette to the different intensities of infrared radiation.

 

Why is Thermal Imaging used for Body Temperature Detection?

 

For several reasons, thermal imaging is used for fever screening and detection. Often, fever screening is set up at border points such as airports, seaports, and public places, which are busy areas with much human traffic at a time. Thermal imaging cameras can solve this problem as they can be set-up to scan a large number of people at one time.

With all fever virus screening cameras in the UK, the incubation period of the virus will affect the temperatures recorded on the human face. Any abnormal face temperature noted within the thermal screening process.

 

As with all fever screening, the incubation period of the virus will affect the temperatures recorded on the human face. In case any abnormal face temperature noted within the thermal screening process, then the person should be checked later by medical professionals and further corrective action taken if required.
