The Valencian company Sothis has launched a pioneering system for measuring body temperature through the eyes that, in real time and without the need for contact, helps identify people with fever when entering facilities. The measurements are carried out in less than a second per person, avoiding queues and contacts, which "makes it an effective prevention system" against COVID-19 to control access to industries, offices, shops or facilities with large flows of people.
The solution, called Thermal Vision System , combines thermal imaging cameras with the company's own software that incorporates Artificial Intelligence to perform the measurement in the subject's tear duct, according to sources from this company, specialized in integrated information technology solutions, industrial management. and business management.
Unlike other technologies, it avoids confusion from external agents , such as overheating of the face caused by the mask and, at the same time, thanks to the vision camera, it can be used to control capacity, access and other applications. According to Email Data Joaquín Guerra , general director of the Industrial Control and Consulting Business Unit of Sothis, in some circumstances the measurements would be incorrect if the entire face were taken as a reference, such as if the cheeks tend to get hotter due to the use of the mask, generating false positives.
For this reason, the solution created by Sothis takes the eye socket as a reference and not the entire facial area, and the precision range of this system has a maximum variation of 0.3 degrees. When the person passes in front of the system, the measurement is carried out and depending on the body temperature detected, the security protocol established by the person in charge of the building continues.
Whether the person can pass if no fever is detected, or if a high temperature has been detected, the message displayed on the screen is customizable for each client, as it is self-developed software. The prototype of Sothis' Thermal Vision System has already been installed in Valencia , through an agreement with Marina de Empresas, and the entrances to the building have become the first to incorporate this technology.
