摘要:为了能利用单一传感器在跌倒撞击前实时检测出跌倒即将发生,结合支持向量机(SVM)和阈值法设计了一种自适应跌倒前实时检测方法.实验结果表明,该方法能在跌倒撞击前实时检测出跌倒即将发生,且比人工阈值法和SVM方法有更长的间隔时间,比SVM方法有更高的召回率和特异度.

关键词: 跌倒前检测, 撞击, 自适应, 实时, 支持向量机

Abstract: To detect falls before falling and to provide basis for fall prevention, this study proposes a self adaptive pre-fall detection method that combines SVM and threshold method. Experiment results show that this method has a longer interval time than the artifical threshold and SVM, and has higher recall rate and specificity than SVM. The self-adaptive pre-fall detection method can detect the fall before the fall impact.

Key words: pre-fall detection, impact, self-adaptive, real-time, SVM
