Abstract

The embodiment of the invention relates to the technical field of gait analysis, and discloses a method for estimating stride length and stride frequency and a device as well as a gait detector; wherein the method comprises the following steps: first gait information and second gait information are received; a first original stride frequency and a first original stride length are determined according to the first gait information; a second original stride frequency and a second original stride length are determined according to the second gait information; data of the first original stride frequency and the second original stride frequency are fused for obtaining a final stride frequency; and data of the first original stride length and the second original stride length are fused for obtaining a final stride length. This method can effectively reduce errors and improve the accuracy in calculating the stride length and the stride frequency during the human walking process.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of gait analysis, in particular to a method and device for estimating step length and stride frequency, and a gait detector. Background technique [0002] Walking is one of the basic activities of human beings. Human gait refers to all the movements, postures and behavior characteristics of the human body during walking. It has significant significance for the detection and analysis of human gait in various fields, such as sports , biometrics, rehabilitation therapy, and health diagnosis. For example, in sports, gait analysis can be used to identify the standardization of athletes' movements, thereby helping athletes correct their movements and improve their personal level; in terms of biometrics, gait analysis can identify people's identities through the way people walk ; In terms of rehabilitation treatment, gait analysis can be used to monitor the recovery of the lower limb motor ab...
