Human body balance measurement method and system based on three-dimensional space motion capture

Abstract

The invention relates to a human body balance measurement method and system based on three-dimensional space motion capture. The method comprises the following steps: collecting actions of a tester to obtain three-dimensional coordinate data of human skeleton points; calculating a balance parameter of each action according to the three-dimensional coordinate data of the human skeleton points; according to the balance parameter, obtaining a balance score through a balance capability calculation formula; and determining the balance ability of the tester according to the balance score. Wherein the actions of the testee are standardized actions and comprise repeated sitting-down and standing-up, series standing, semi-series standing and standing-up walking tests. The invention provides a set of standardized balance test actions and quantitative balance parameters, provides a scientific, objective and standard balance capability calculation formula, quantifies the balance capability, corresponds to the balance capability level, does not need to wear any sensing equipment, enables a tester to execute the test actions in a completely natural state as much as possible, and improves the test efficiency. And balance capability parameter evaluation can be rapidly and conveniently carried out.

Description

technical field [0001] The invention belongs to the technical fields of information technology and balance measurement, relates to the measurement of the balance ability of the human body, and in particular relates to a method and system for measuring the balance of a human body based on three-dimensional space motion capture. Background technique [0002] At present, there are mainly two types of balance measurement methods. One is through the balance scale (Tinetti balance and gait scale). This method mainly relies on subjective judgment. Whether it is stable during the action process or whether the left and right feet are symmetrical during the walking process, there is a non-standard measurement process, and the subjectivity of the judgment results will affect the final measurement conclusion; the other is to use wearable sensors (pressure sensors, etc.), such methods Pre-measurement preparation is cumbersome, requiring sensors to be worn, calibration, or the measurement...

AI Technical Summary

Problems solved by technology

[0004] The existing balance measurement methods have problems such as non-standard measurement process, highly subjective judgment results, cumbersome preparations before measurement, need to wear sensors, calibration, or the measurement environment has many restrictions and high requirements, which affect the normal performance of the testers, resulting in the measurement The results do not reflect the true level of the tester
