Problems solved by technology

[0005] The present invention provides a method and system for processing plantar pressure based on periodic modal information to solve the problems in the prior art in the above-mentioned background technology. Because the existing plantar pressure analysis mostly deals with the static state generated by multiple fitting and superimposition Pressure distribution diagram or pressure center transfer diagram, this detection method leads to serious over-interpretation of data, and related data analysis methods and methods change with equipment suppliers

Embodiment

[0079] This embodiment: as figure 1 As shown, the method for processing plantar pressure based on periodic modal information includes collecting the raw data S101 of the gait of the cyclic modal through multiple sets of sensors, and passing the preprocessed raw data of the gait of the cyclic modal through the stability Determine the evaluation value S102 of stability and symmetry with the symmetry processing method, gather multiple sets of evaluation values ​​of stability and symmetry to form evaluation information S103, and comprehensively judge the change analysis of stability and symmetry in the process of human walking through the evaluation information Difference S104 between different foot pressure data.

[0080] Since the original data of the gait of the periodic mode is collected by multiple sets of sensors, the evaluation value of stability and symmetry is determined by the stability and symmetry processing method of the raw data of the preprocessed gait of the period...

Abstract

The invention belongs to the technical field of gait analysis, and in particular relates to a method for processing plantar pressure based on periodical modal information. At the same time, the invention also provides a system for processing plantar pressure based on periodical modal information. The original data of the gait of the state is determined by the stability and symmetry processing method to determine the evaluation value of stability and symmetry, and multiple groups of stability and symmetry evaluation values ​​are assembled to form evaluation information. The present invention solves the existing problems in the prior art due to Most of the existing plantar pressure analysis is to deal with the static pressure distribution map or the pressure center transfer map generated by multiple fitting and superimposition. This detection method leads to serious over-interpretation of the data, and the relevant data analysis methods and methods change with the equipment provider. The problem has the beneficial technical effect of avoiding serious over-interpretation of data, preventing relevant data analysis methods and means from changing with equipment providers, high precision of data processing, and good intuitiveness.

Description

technical field [0001] The invention belongs to the technical field of gait analysis, and in particular relates to a method for processing plantar pressure based on periodical modal information. At the same time, the invention also provides a system for processing plantar pressure based on periodical modal information. Background technique [0002] Gait analysis (gait analysis) is a technology that obtains and analyzes gait parameters by observing or collecting the posture of the human body during walking. Common gait parameters include spatial parameters (stride length, step length, step width, etc.), Time parameters (standing / swing period, single step time, stride frequency, etc.), and the symmetry of the left and right feet of these parameters, the stability of long-term data, etc. Plantar pressure is the reaction force of the ground on the sole of the foot in the vertical direction under the action of its own gravity when the human body is standing still or walking dynam...
