Embodiment Construction

[0059] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that when an element is said to be "fixed" to another element, it may be directly on the other element, or there may be one or more intervening elements therebetween. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or one or more intervening elements may be present therebetween. The terms "vertical", "horizontal", "left", "right", "inner", "outer" and similar expressions are used in this specification for the purpose of description only.

[0060] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the technical field of the invention. The terms used in the description of the...

Abstract

The embodiments of the invention relate to the technical field of step length measurement, and disclose a step length measuring method, device and system and a nonvolatile computer storage medium. Thestep length measuring method comprises the steps that in each gait cycle, swing angles of a thigh and a shank in each foot in the sagittal plane of human body motion are obtained; relative change angles of two feet in each gait cycle are obtained; the respective length of the thighs and the shanks are determined; and the swing angles of the thigh and the shank in each foot in the sagittal plane of human body motion, the respective length of the thighs and the shanks and the relative change angles are treated through a step length measurement model, and the step length is obtained. Therefore,on the one hand, even if a deviation exists between a coordinate system of an installation sensor and a human anatomy coordinate system, the accurate step length can further be obtained through the method; and on the other hand, when the step length is measured, the method does not need to preset the calibration action, and the problem that step length measurement is tedious is avoided.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of step length measurement, and in particular to a step length measurement method, equipment, system, and non-volatile computer storage medium. Background technique [0002] The measurement of step length has important reference value for the diagnosis and prevention of some diseases, especially in Parkinson's syndrome. [0003] Generally, various sensors are installed on the subject in the traditional technology, and the sensor can collect the angular velocity of the thigh or calf of the subject when walking, and calculate the step length according to the angular velocity. [0004] In the process of implementing the present invention, the inventors found at least the following problems in the traditional technology: the step length measurement is inaccurate due to the deviation between the coordinate system where the sensor is installed and the anatomical coordinate system of the human...
