Research progress of elderly fall detection systems and its detection methods
Accidental falls are the main cause of injuries and deaths of the elderly.Therefore,researches on fall intelligent detection systems increase unceasingly.Fall detection systems are classified into four categories:wearable,indoor non-image,indoor image,and hybrid systems.Technical feature of each category is explained and various sensors used in fall detection systems are summarized.In addition,main process and content of fall detection are introduced.The main methods for fall determination,threshold analytical method and machine learning are stated.Finally,the shortcomings of the fall detection system are analyzed.In the future,with continuous improvement,fall detection systems will have broad application prospects.
