The AI temperature monitoring system was put into use at the Qinghe High-Speed Railway Station in Beijing to measure the temperature of commuters. The station is along the Beijing-Zhangjiakou high-speed railway. When passengers exit the station, this system can scan their faces and detect the body temperature. Passengers whose temperature is found higher than the set value will be taken aside for manual retesting. This device can monitor 50 people on the screen at a time and results are unaffected even if someone is wearing a mask. Photos: Li Hao/GT
