Abstract:In order to meet the needs of real-time and multi-dimensional monitoring of human health information and improve the work efficiency of guardians, a health monitoring system for human physiological parameters and expression recognition is designed. Through sensors, cameras and other equipment, human physiological indicators and video data are collected in real time. The core control layer and server perform centralized analysis and processing, and the monitoring results are displayed through the PC interface. It helps guardians pay real-time attention to the physical condition and emotional changes of the ward and take timely intervention measures. The experimental results show that the average error of the system in monitoring human blood oxygen saturation is within 0.6%; the average error in monitoring human heart rate is within 0.3 bpm; the average error in monitoring human body temperature is within 0.13°C; the accuracy of facial expression recognition is 96.62%, it has the ability to monitor multi-dimensional health information of the human body, can solve the problem of real-time monitoring of human physiological parameters and emotional changes, and effectively improve the work efficiency of monitoring personnel.
