Abstract

Abstract: In recent years, the health problems of the elderly have been paid more and more attention. Fall is one of the main reasons that affect the health and safety of the elderly. The research interest has always been high, and high-quality fall detection algorithms have emerged one after another. This article summarizes the research significance of fall detection and existing popular research methods, and then summarizes fall detection algorithms based on a threshold, machine learning, and deep learning from the perspective of a single algorithm and hybrid algorithm. Then it introduces the detection methods of each algorithm, judgment methods, overall performance, and the advantages and disadvantages of various single algorithms, and focuses on the prominent role and application of convolutional neural networks in the field of falls from the three dimensions of time, space, and spacetime. At the same time, the data set used by the fall detection algorithm and its characteristics are introduced, so that researchers can understand the latest research progress of fall detection in terms of threshold, machine learning, and deep learning. Finally, the challenges and future development of the fall detection algorithm have prospected.
