成果介绍

本发明涉及基于地面振动信号的人体摔倒检测方法，三个地震检波器采集地面振动信号；对采集的振动信号进行滤波降噪、端点切段处理、对齐处理；然后对信号进行叠加、信号特征提取；将提取到的特征信号组成训练集用于训练隐马尔可夫模型；以实际使用时的地面振动信号作为测试数据，以处理训练数据的方法处理测试数据；基于隐马尔可夫模型计算摔倒的概率，并结合EoA定位算法对短暂时间段内进行坐标跟踪，若目标移动范围小于阈值，则二次确认为摔倒，否则不为摔倒。还涉及人体摔倒检测系统。本发明通过隐马尔可夫模型计算振动信号为摔倒的概率再结合定位算法EoA进行二次确认，对摔倒的识别准确且误报率低，不需穿戴设备，保护隐私隐患，提升了用户体验。
