Public safety video surveillance has played an important role in the battle against Corona virus disease 2019. Aimed at the characteristics of high population density, large flow of people, and the easy spread of Corona virus disease 2019 in China, an intelligent temperature detection and health big data management system combining visible and infrared dual-spectral imaging monitoring is established to achieve contactless rapid temperature detection and face recognition while wearing a mask, and to quickly complete the registration of personal information. The system has been deployed in multiple places, and has passed the verification of effectiveness and reliability. The measurement speed is fast and the response time is within 30 ms. The measurement accuracy is high and the measurement temperature error is within ±0.3℃. The measurement range is wide and the monitoring distance is 0.1-10 m. The face capture rate is over 99%, and the recognition rate is over 95%. The health big data management system can monitor and track back-to-back personnel movements in real time, perform statistical analysis on personnel information and epidemic development big data in multiple dimensions, conduct epidemic development trends modeling and prediction, improve epidemic prevention and control strategies based on the analysis results, and carry out accurate and efficient epidemic prevention and control.
