Abstract

With the help of thermal imaging sensors and AI-based software, people with fever can be recognized contactlessly and in real time. The aim of this technology is to recognize changes in body temperature as a sign of infection, in order to treat infections early and to break the chain of infection. The infrared thermography (IRT) access system from the Berlin company G2K evaluates the thermal signatures of the arriving people using a thermal imaging camera and a black body (black body radiator), which as an IR reference radiator resembles an idealized physical body that absorbs all incident electromagnetic radiation. During the application observation period, 1,832 people were detected and measured without contact. 1,261 people (68.8%) were admitted to the emergency room. 257 patients (20.4%) showed signs of infectious disease using IRT and IR control temperature measurements, of which 12 patients (4.7%) suffered from coronavirus infections. 245 patients suffered from bacterial and / or viral diseases with an increase in body temperature> 37.3 ° C. The measuring accuracy checked in the emergency room was 98.6% and therefore has a deviation of 1.4% from the infrared temperature measurement in the ear.
