Gait Recognition Based on Inertial Sensor

Abstract

As a new biometric technology,gait recognition has become a research hotspot of biometric technology due to its advantages of non-contact,non-interference,long-distance and difficult to camouflage.In addition,in recent years,due to the maturity of MEMS inertial sensor technology and its wide application in portable devices,gait recognition based on inertial sensors has attracted more and more attention from researchers.This paper collects and sorts out the research methods and research status of gait recognition using inertial sensors at home and abroad,and reviews the relevant technologies in this field.According to the sequence of recognition processing,the paper reviews the relevant technologies and research status of data acquisition,data preprocessing,data segmentation,feature selection and combination,and intelligent recognition in each stage.At the same time,the main public gait databases are given for the convenience of interested readers.Finally,on this basis,the technical difficulties of gait-based recognition are discussed,and the future development directions are prospected.
