Chinese artificial intelligence (AI) start-up Face has developed a temperature screening tool that can help monitor human body temperature in crowded places and identify individuals who might have a fever using facial recognition technology. The system is on a trial-run in some subway stations and government offices in Beijing's Haidian district amid the novel coronavirus outbreak, the company said in a statement sent to the Global Times Wednesday. The AI system includes an infrared camera, which enables temperature screening from a distance of over three meters with an identification error within 0.3-degree centigrade, as well as an intelligence terminal. Once it detects suspected febrile person, it raises an automatic alarm and quickly reports the position of the individual based on the company's self-developed person re-identification facial recognition technology. The system's alarming bandwidth could report 15 persons per second, according to the statement.
