摘 要: | 为减轻中青年赡养老年人的压力,借助Android手机普遍性的优点,提出一种基于Android手机的老年人跌倒检测算法。该系统基于人体不同行为下的加速度和身体所处高度值的变化特征,通过数据采集、数据滤波、数据特征提取等过程,并在现有方法的基础上,引入对失重数据的统计分析,实现对跌倒行为与其他日常行为的区分;在系统检测出老人跌倒时,将老人位置等信息以求救的形式通知监护人。实验表明,设计的基于Android手机的老年人跌倒检测方法在满足一定条件的环境中具有较高的准确率。 |

Abstract: | In order to reduce the pressure of young people to support the elderly, this paper takes the advantages of the universality of Android mobile phones to design a fall detection algorithm for elderly people. The system is based on the change of acceleration and height value of the body. Through the process of data acquisition, data filtering, data feature extraction and so on, and on the basis of the existing methods, the statistical analysis of weightlessness data is introduced to distinguish the falling behavior from other behaviors. When the falling behavior is detected, the system will send the location and other information of the elderly to guardians in the form of notices. Experiments show that the Android mobile phones-based system of fall detection for the elderly have high accuracy rate in the environment of a certain condition. |
