基于表情识别技术的独居老人智能监护系统

Intelligent Monitoring System for the Elderly Living Alone Based on Facial Expression Recognition Technology

摘要: 本文简要介绍了基于表情识别技术的独居老人监护系统。该监护系统主要由摄像头、电脑两部分组成，它的开发思路是用摄像头捕获画面；用电脑控制整个系统和操作流程，旨在通过表情实时测量老人日常精神状态。本项目开发的独居老人监护系统是能够通过面部特征点变化判断其是否需要医护人员帮助的智能监护系统。测试结果表明，该系统能准确识别被监护者表情变化并立即发出报警信号，解决了老人痛苦或失去意识时的急切的监护需求，甚至还因及时预警从而增加了抢救时间，为老人提供了多重安全防护。

Abstract: This paper briefly introduces a monitoring system for the elderly living alone based on facial expression recognition technology. The monitoring system is mainly composed of a camera and a computer. Its development idea is to use the camera to capture the picture; use the computer to control the entire system and operation process, aiming to measure the daily mental state of the elderly in real time through facial expressions. The monitoring system for the elderly living alone developed in this project is an intelligent monitoring system that can judge whether they need the help of medical staff through changes in facial feature points. The test results show that the system can accurately identify the change of the person’s expression and send an alarm signal immediately, which solves the urgent monitoring needs of the elderly when they are in pain or lose consciousness, and even increases the rescue time due to timely early warning, providing multiple Security.
